c. Equivalent to a law.
d. Equivalent to both a theory and a law.
2. The layer that encompasses an entire tectonic plate is called:
a. Asthenosphere
b. Crust
c. Mesosphere
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.
