Geological Events (Unit 4) Review for Test

Which of the following shows where the asthenosphere, mantle, and core would be labeled on a model of Earth’s layers?

• 
• 
• 
• 

The picture shows a diagram of Earth’s layers. What is happening at point W?

• Energy from the Sun heats the crust, causing it to shift and pull the tectonic plates, which uses friction to heat the magma in the mantle.

• Energy from the Sun heats the crust, which conducts heat to the mantle, causing the magma to warm and sink toward the core, pulling the tectonic plates.

• Water in the mantle is being heated by the hot crust, which causes it to sink toward the core where it cools, the convection circuit pulling the tectonic plates.

• Magma in the mantle is being heated by the hot core, causing it to rise toward the crust, then sink as it cools, the convection circuit pulling the tectonic plates.

The picture shows a model of Earth’s layers. Which statement best describes layer 2?

• It is the liquid outer core made mostly of nickel and iron

• It is the upper mantle made mostly of solid rock

• It is the solid inner core where semi liquid magma flows

• It is the lithosphere where Earth’s heat is generated

Which letter represents the layer that is thin, rocky, and is the least dense of all Earth’s layers?

• Layer 5

• Layer 4

• Layer 3

• Layer 2

Which is layer 1?

• The outer core, which is a rigide, loose layer with low temperatures

• The crust, which is liquid and composed mainly of nickel and iron

• The inner core, which is a solid, dense layer made mostly of iron

• The lithosphere, where liquid magma convects in circular patterns.

Which statement describes layer 3 & 5?

• Layer 3 is the crust and Layer 5 is the mantle; both layers are cooler than Layer 1.

• Layer 3 is the mantle and Layer 5 is the crust; both layers are cooler than Layer 1.

• Layer 3 is the mantle and Layer 5 is the crust, both layers are hotter than Layer 1.

• Layer 3 is the crust and Layer 5 is the mantle; both layers are hotter than Layer 1

The picture shows a hard-boiled egg, where the shell is a model for the lithosphere of Earth. Which part of the egg represents where earthquakes would be most likely to occur?

• At the top, where the shell is the most vulnerable because of its point

• At the bottom, where the egg is widest, because this part of the shell is thickest

• Along the smoothest part, where the pieces cannot release stress when the shell is moved

• Along the cracks, where the pieces would rub and grind against each other when the shell is moved

Where does volcanic activity occur on the ocean floor?

• In the trenches when sediment moves

• On continental shelves

• along rift zones in mid-ocean ridges

• on continental slopes

Which explanation describes why seafloor spreading occurs?

• Lithospheric plates rub together under the ocean floor.

• Lithospheric plates move apart under the ocean floor.

• Lithospheric plates join together under the ocean floor.

• Lithospheric plates are formed under the ocean floor.
