Tectonic plates are parts (pieces) of the outermost layer of Earth: the Crust. (the outermost part of the mantle is also often included in the plates). This means that the land in the middle of the plates is relatively stable while the borders of the plates can be in movement - after all this is where two pieces meet. Plate borders are where the vocanoes and Earthquakes often take place.
Answer:
Convection currents drive the movement of Earth's rigid tectonic plates in the planet's fluid molten mantle. In places where convection currents rise up towards the crust's surface, tectonic plates move away from each other in a process known as seafloor spreading.
Explanation:
Answer:
The emergence of a highly competitive species, Homo sapiens.
Explanation:
Neanderthals were the closest ancestors to the human being we know, however, the body structure of Neanderthals, the less developed brain and the adverse climate of the region where they lived made the emergence of Homo sapiens a great plot twist responsible for the end of Neanderthals .
This is because Homo sapiens had characteristics that made it a very competitive species. These characteristics were advantageous in relation to the characteristics of Neanderthals. Among these characteristics we can mention the production of keratin to strengthen the skin, and the efficient covering of hair and nails that protected against the cold.
