Geosphere

Structure of Geosphere

100

Which part of the geosphere is the thickest?

mantle

200

Which layer of the geopshere is made of liquid iron a.) asthenosphere b.) mantle c.) inner core d.) outer core

Outer core

300

Convection currents help drive the process of plate tectonics. Which mechanical part of the geopshere do these currents occur at. a.) Outer core b.) Crust c.) Lithosphere d.) Asthenosphere

d.) Asthenosphere

400

The process of the rock cycle take place in which location? a.) deep inside the geopshere b.) in the atmosphere c.) on Earth's surface d.) both a and c

d.) Both A and C on the earth surface (lava cooling and deep inside)

500

What are the two types of crust that make up the earth's lithosphere? Which type is thinner/thicker? Which is more dense/less dense

Continental and Oceanic Crust. Oceanic crust is thinner but more dense while Continental is thicker but less dense.

Misc.

100

This term describes the mass per volume of a material. Also described as the number of molecules in a defined space or "compactedness".

Density

200

This term is defined as data or facts to prove a hypothesis or claim.

Evidence

300

This keeps the atmosphere intact. Without this the solar winds would blow it away.

the Earth's magnetic field

400

This is what creates earth's magnetic field

Convection in the outer core.

500

What are the four pieces of evidence that support that the Earth has layers.

1. Meteorites

2. Laboratory experiments

3. Seismic data

4. the Earth's magnetic field

Plate Tectonics

100

This is the type of boundary when two plates are moving away from each other.

Divergent boundaries

200

This type of boundary is formed when two plates collide.

Convergent

300

This is the type of boundary when plates move past each other. An example of this type of boundary is the San Andreas fault in California.

transform boundary

400

Name 3 things that are formed at a convergent, subduction, boundary.

Volcanoes, mountains, trenches

500

When looking at a divergent boundary, where is the newer rock and where is the older rock. 

newer at the boundary, older further out as the plates push outward.

Earthquakes and Volcanoes 1

100

What location does most volcanic and seismic (earthquake) activity occur in the world?

Ring of Fire

200

What type of crust is more dense?

oceanic

300

What is the range of intensity of an earthquake and what is it called?

1-10, ritcher scale

400

What is more dense older crust or younger crust (oceanic)

older

500

What type of rock is formed from compaction and cementation.

sedimentary

Earthquakes and Volcanoes 2

100

What is melted rock under the surface of the Earth called?

Magma

200

S-waves travel through:

Media, but not liquid

300

P waves travel through

All types of media

400

Melted rock that comes up to the surface is called

lava

500

This type of rock is formed through heat and pressure.
