d. Lithosphere

3. The outer layer of the Earth defined by its composition is called:

a. Crust

b. Mesosphere

c. Asthenosphere

4.The layer that sits directly under the lithosphere is called:

a.Crust

b. Mesosphere

c.Asthenosphere

5. The core of the Earth is composed primarily of:

a. Hydrogen

b. Oxygen

c. Silicon

d. Iron/Nickel

6. How does the mesosphere behave?

a. As a brittle solid

b. As a liquid

c. As a ductile solid

d. As a gas

7. The layers defined by their physical properties include all of the following except:

a. The mesosphere

b. The asthenosphere

c. The inner core

d. The Crust


Explanation / Answer

answer 1: a

see scientific method is an approach to understand how the phenomenon is going on , we investigate the phenomenon and modify the existing theories related to this phenomenon.

answer 2 d

lithosphere encompasses an entire tectonic plate. It is made up of crust and upper part of mantle.

answer 3 a

crust

answer 4 asthenosphere

answer 5: iron and nickel

see iron and nickel are densest metals because of high density they settle in the center of the earth i.e core.

answer 6: as ductile solid

answer 7: the crust its base on chemical properties rather than physical.
