  • 4 Major Types Of Wind - 1,616 words
    4 Major Types of Wind subject = Science title = 4 Major Types of Wind Wind, Its So Much More I did my report on wind. As you may or may not know wind moves horizontally, and the wind that doesnt move horizontally moves vertically. That kind of wind is called a current. Many things may cause these rushes of moving air, one thing would be atmospheric pressure differences. The differences in the distribution of pressure and temperature is caused by the unequal distribution of heat. There are also the differences in the thermal properties of land and the ocean surfaces. When the temperatures of different regions become unequal, the warmer air will normally rise and move over the cold air because ...

  • Atmospheric Circulation And More - 688 words
    Atmospheric Circulation and More The global energy balance and atmospheric motion mainly determine the circulation of the earth's atmosphere. There is a hierarchy of motion in atmospheric circulation. Each control can be broken down into smaller controlling factors. The global energy balance is an equal balance of short-wave radiation coming into the atmosphere and long-wave radiation going out of the atmosphere. This is called thermal equilibrium. The earth is at thermal equilibrium; however, there can have a surplus or deficit of energy in parts of the heat budget. If you have a net radiation surplus warm air will rise, and a net radiation deficit will make the air cool an fall. Air gets h ...

  • Australia - 1,946 words
    Australia Australia The name of Australia comes from the Latin word Australis, which means southern. Since it lies entirely in the southern hemisphere, Australia is most commonly referred to as "down under". Australia, being a country, is also a continent. In land area its the sixth largest for a country and the smallest continent. Australia is a very dry, thinly populated country. Very few coastal areas receive enough rainfall to support a large population. The largest group of Australian people live in two large cities, Sydney and Melbourne. The vast interior is mainly desert or grassland and there are very few settlements. As a whole, the country has a density of six people per square mil ...

    Australia Australia is the only country that is also a continent. In area, Australia ranks as the sixth largest country and smallest continent. Australia is located between the South Pacific Ocean and the Indian Ocean. The part of the Indian Ocean that is south of Australia is called the Southern Ocean in the country. Australia is about 7,000 miles (11,000 kilometers) southwest of North America and about 2,000 miles (3,200 kilometers) southeast of mainland Asia. Australia is often referred to as being "down under" because it lies entirely within the Southern Hemisphere. The name Australia comes from the Latin word australis, which means southern. The official name of the country is the Commo ...

  • Cold Water Discovered In The Subtropical Atlantic Was Brought There By A Current Which Had Originated In The Polar Region Tem - 638 words
    Cold water discovered in the subtropical Atlantic was brought there by a current which had originated in the polar region; temperature measurements in the real ocean and computer models show there is a southward outflow of cold deep water from the Arctic throughout the Atlantic. This cold water is replaced by warm surface waters, which gradually give off their heat to the atmosphere as they flow northward towards Europe. This acts as a massive heating system for all the land downwind. The heat released by this system is enormous: it measures around 1015 W, equivalent to the output of a million large power stations. If we compare places in Europe with locations at similar latitudes on the Nor ...

  • Constellations - 601 words
    CONSTELLATIONS Constellations are groupings of the brighter visible stars in the night sky. Many of these groupings are based on imaginary figures that are seen on the inner surface of a huge sphere surrounding the earth. They divide the celestial sphere into 88 constellations, 47 of which date from ancient times and were listed by the astronomer Ptolemy. The boundaries are often complex. But all segments of the boundaries lie ease-west and north-south on the celestial sphere. Constellations are used today to show general directions in the sky. The constellations may be divided into three groups: (1) the equatorial constellations, which lie on each side of the celestial equator, the projecti ...

  • Earth Planet - 2,166 words
    Earth Planet The Earth, man's home, is a planet. The Earth has special characteristics, and these are important to man. It is the only planet known to have the right temperature and the right atmosphere to support the kind of environments and natural resources in which plants and man and other animals can survive. This fact is so important to man that he has developed a special science called ecology, which deals with the dependence of all living things will continue to survive on the planet. Many millions of kinds of plants and animals have developed on Earth. They range in size from microscopic plant and animals to giant trees and mammoth whales. Distinct types of plants or animals may be ...

  • Exploring Mars - 1,479 words
    Exploring Mars MARS SURFACE EXPLORATION One question that is being asked by people is, "Why go to Mars"? The reasons are very simple. People want to gain recognition of how they were the first people who went to Mars and opened up a whole new world and most importantly to move forward in economics. As humans waste the precious materials and resources found on this planet we have to consider going to other planets to explore for materials and energy resources. Mars would be the first area for industrial development and mining in the "new world". There are talks that by the end of this century that a manned mission to Mars should take place. We must start preparing ourselves properly in order ...

A professional astronaut would have the skills to easily spot a protected site that would be favourable to life. An example of this would be a spot sheltered by a rock. Equipment which is automatic that astronauts have is better for things like, repetitive measurements which would be stretched over long periods of time. Scientific research will be divided into two main categories. There would be a day to day exploration by the astronauts which would have more difficult tasks. They would also be resp ...

  • Hurricanes - 1,193 words
    Hurricanes Summer is over and fall has arrived- but many people to the south of us are observing another season- hurricane season. According to the Montshire Museum of Science, "hurricanes usually occur in the North Atlantic from June to November, with most of them in September." On average, between six to eight hurricanes form in the North Atlantic or North Pacific each year (Montshire). However, as many as 15 have occurred in the Atlantic in a single year. Hurricanes are powerful, whirling storms that measure several hundred miles in diameter. The winds near the center of a hurricane blow at speeds of 74 miles per hour or more (World Book, 400). Many hurricanes leave a trail of widespread ...

A hurricane is a powerful whirling storm of winds that measure 200-300 miles in diameter. Hurricanes are an area of low pressure that forms over the oceans in tropical regions in either the north Atlantic Ocean or eastern north Pacific Ocean. In the west Pacific Ocean hurricanes are called typhoons, and in the Indian Ocean they are called Cyclones. Hurricanes develop from easterly waves that over the oceans warm waters. These easterly waves are long narrow regions of low pressure ...

  • Jungle And The Rain Forest - 786 words
    Jungle and The Rain Forest Jungle and rain forest are terms that are often used synonymously but with little precision. The more meaningful and restrictive of these terms is rain forest, which refers to the climax or primary forest in regions with high rainfall (greater than 1.8 m/70 in per year), chiefly but not exclusively found in the tropics. Rain forests are significant for their valuable timber resources, and in the tropics they afford sites for commercial crops such as rubber, tea, coffee, bananas, and sugarcane. They also include some of the last remaining areas of the Earth that are both unexploited economically and inadequately known scientifically. The term jungle originally refer ...

  • Jupiter Moons - 1,332 words
    Jupiter Moons Jupiter, the largest of the Jovian planets, reigns supreme throughout the solar system. Named after the Roman god Jove, the ruler of Olympus; "Jupiter is the fifth planet from the sun and is also the largest planet in the Earth's solar system. It is 318 times moremassive than Earth and is two thirds of the planetary mass in the solar system. Jupiter's surface, unlike earth, is gaseous and not a solid. It is about 90% hydrogen and 10% helium with traces of methane, ammonia, water and rock. Jupiter's interior is very similar to the Sun's interior but with a far lower temperature."(Columbia) However, it is still unknown for certain, but Jupiter is believed to have a core of liquid ...

    Mars Mars is the fourth planet from the sun and orbits the sun at a distance of about 141 million mi. Mars is named for the Roman god of war because it appears fiery red in the earths night sky. Mars is a small planet that has about half the diameter of Earth and about one-tenth Earths mass. The force of gravity on the surface of Mars is about one-third of that on Earth. Mars has twice the diameter and twice the surface gravity of Earths moon. The surface area of Mars is almost exactly the same as the surface area of the dry land on Earth. The Martian day, or the time it takes Mars to rotate once on its axis, is about a half an hour longer than an Earth day. Its year, or the time it takes to ...

  • On The Beach - 1,256 words
    On The Beach On The Beach In the big city of Melbourne, Australia, material goods have become scarce. There are no cars, and very little of the luxuries that there once were. It takes hours to get simple necessities such as milk. All this is because of the nuclear war in the Northern Hemisphere. This nuclear war has wiped out every living thing, including all humans, throughout countries like China, Europe, and even the United States. It all began with a fight between Russia and China, who wanted to destroy each others land. They managed this with nuclear bombs, and without realizing the consequences, killed off their own people along with everybody else due to the radiation that was left be ...

  • Penguins - 1,512 words
    Penguins The signature Species of the Southern Hemisphere (Antarctica) - the mascot if you will - is the penguin. There are not one and no fewer than seventeen species of penguins. Penguins are flightless birds in which several factors are contributing to the reduction of the penguin population. These contributing factors are both man-made and naturally occurring. The origin of the word penguin has been the subject of debate for a long period of time. Researchers and historians theories range from reference to the amount of fat (penguigo in Spanish and pinguis in Latin) penguins possess to the claim that the word was derived from two Welsh words meaning white head. (Sparks and Soper, 1987) P ...

II Explanation 1 Physical characteristics A Most penguins have a white breast and a black back and head. Many species exhibit red, orange, or yellow patches on the head and neck. Because their short legs are placed far back on their bodies, penguins assume an upright posture. B Penguins are grouped into 18 species and 6 genera, most of which are found in Antarctica and on subantarctic islands. Others are native to the coasts of Australia, South Africa, and South America and to the Galapagos Islands. C The largest species are the king penguin, from 36 to ...
