  • Biology And Human Evolution - 1,381 words
    Biology And Human Evolution Human Biology and Evolution Humans are Alive The earliest human life form can be traced back more than 3.5 billion years ago. Humans are said to be descendants of a single celled ancestor. Although they are different in size and shape all basic functions are alike. The more complex the organization of the cell became the more successful and developed it became. As these single celled organisms developed they became known as pre-humans.

  • Principle Of Superposition - 1,192 words
    ... ent kinds of active plate boundaries. An example of the most well known and studied fault is the San Andreas Fault located of the coast of California. 11. The origin of volcanoes: Hot spots, can be found on plate boundaries or inside the plates. The hot spot is a place deep inside the Earth that begins to form molten lava from extreme heat conditions. It will quickly rise up, pushing and melting its way to the surface resulting in a volcano. Because of the constant moving of the plates, the volcano will be carried away from the hot spot and become dormant. This process will repeat itself, forming a never-ending row of volcanoes. 12. The crust, being the absolute outer layer of the Earth ...
