2. In your own words, describe an earthquake.

3.What is the least dense and most dense layer of Earth, and why?

4. What are the 2 types of crust of Earth?

5.What are the 2 types of earthquake waves? Which waves are fastest?

6. What is an indirect observation?

7. What are the four layers of the mantle?

8. Why is the outer core liquid but the inner core solid?

Answer 1

1)The earth is made up of three different layers: the crust, the mantle and the core.

2) I think an earthquake is when the tectonic plates form together and progress movement which cause floor shakiness and everything falls.

3) Earth's interior layers are ordered by density. The densest layer is the solid metal inner core, the mantle is of intermediate density, and the least dense layer is the lithosphere, particularly the continental lithosphere.

4) Earth's crust is divided into two types: oceanic crust and continental crust.

5)Surface waves travel along the surface. There are two types of body waves: P-waves travel fastest and through solids, liquids, and gases; S-waves only travel through solids. Surface waves are the slowest, but they do the most damage in an earthquake.

6)Indirect observation involves the analysis of textual material generated either indirectly from transcriptions of audio recordings of verbal behavior in natural settings or directly from narratives.

7)The mantle is divided into several layers: the upper mantle, the transition zone, the lower mantle, and D” , the strange region where the mantle meets the outer core.

8)The outer core is not under enough pressure to be solid, so it is liquid even though it has a composition similar to the inner core. Sulfur and oxygen could be present in the outer core.
