How does natural selection “drive” evolution?
yanalaym [24]

Because predators and prey must learn (or adapt) new ways of survival. Deer over time have learned to be much more sensitive to the surrounding environment, therefore, a deer's predator must also adapt/evolve and learn how to beat the deer at it's own game and catch it for food. Animals must evolve/adapt to any given environment. If humans lived in Antarctica for thousands of years, we would eventually be able to withstand the cold due to evolution. People who live in the Himalayas today actually breath normally at such high altitudes whereas if someone who lives at sea level went to where the Himalayan people lived, the result could potentiality be fatal because the body has not adapted/evolved at that point to withstand minimal oxygen.

Tectonic plates are pieces of the ________ that float on the more fluid ________ below. A. mantle; crust B. asthenosphere; litho
Soloha48 [4]

Answer:

The answer is E.) Lithosphere, Asthenosphere.

Explanation:

Tectonic plates belong to the layer called Lithosphere. The tectonic plates float on the Asthenosphere which is below the Lithosphere and more fluid than the crust.

From the Earth's surface to the its center we can say that the inside of the Earth is divided into four layers which, starting from the top , are:

i) the crust

ii) the mantle, (Lithosphere, Asthenosphere , Mesosphere)

iii) the outer core

iv) the inner core.

The tectonic plates are part of the Lithosphere and are constantly moving even though the crust is fairly solid. This is because the inner layers

( Asthenosphere , Mesosphere) are much are fluid and are constantly moving which tends to move the tectonic plates. When the tectonic plates collide they do so with tremendous force which leads to earthquakes and sometimes tsunamis as well resulting in a loss of life and property.
