Geology Part 1 Review

1.What is the main method of heat transfer from the core to the crust of Earth?

• convection
• insulation
• conduction
• radiation

2.What is the densest part of Earth?

• crust
• mantle
• lithosphere
• core

3.The outer core of the earth is primarily made of

• primarily water
• unknown materials
• molten metal
• solid metal

4.If you were to travel from the surface to the center of Earth, the temperature would

• decrease dramatically
• increase dramatically
• stay about the same
• increase minimally

5.In the diagram of the ocean basin, where is the oldest oceanic crust found?

• A
• B
• C
• D

6.The movement of tectonic plates shown here is MOST LIKELY the cause of

• droughts
• tornadoes
• hurricanes
• earthquakes

7.The convection shown in the diagram is powered by heat from which part of the Earth?

• crust
• ocean
• sun
• core

8.Geologists trying to drill into the mantle would MOST LIKELY drill from a platform in the ocean, rather than on land, because the crust beneath the ocean is

• less dense
• older
• softer
• thinner

9.What type of plate boundary is shown in this illustration?

• convergent boundary
• mantle boundary
• transform boundary
• divergent boundary

10.How does the density of the Earth’s core compare to the other layers of the Earth?

• The core is only less dense than the crust.
• The core is the densest layer
• The core is only less dense than the mantle.
• The core is the least dense layer.
