Answer explanation

This question links to success criteria 2.5.1: I can identify and describe the three layers in Earth’s interior.

If you got it correct place a check mark in the question results section. If you got it incorrect place an X in that section. If this was a redemption question, cross out the one X and replace it with a check mark.

Which of the following best describes the crust?

• A hot liquid layer between 2,900 and 5,100km deep

• A hot layer of plastic solid that is involved in the creation of new crust.

• A thick solid rocky layer, older in the ocean than on the continents

• A thin, solid, rocky layer, denser and younger in the ocean than on the continents

2.5.2

Which of the following best describes the way seismic waves move through various materials

• Seismic waves always slow down over time

• Seismic Waves always speed up over time

• Seismic waves travel slower through hotter materials and faster through colder materials

• Seismic waves travel slower through colder materials and faster through hotter materials

Answer explanation

This question links to success criteria 2.5.2: I can use seismic wave data as evidence of different temperatures, pressures and compositions in each layer.

2.5.2

Which of the following is an accurate observation about the movement of seismic waves through the earth's mantle?

• The waves do not always travel the same speed through the mantle which means that parts of the mantle have different temperatures

• The waves do not always travel the same speed through the mantle because there are multiple types of waves in the mantle

• The waves do not travel the same speed through the mantle because the moon is moving

• The waves do travel the same speed through the mantle but there are additional layers we haven't discovered

Answer explanation

2.5.2

The different speeds of seismic waves throughout the layers of the earth is proof that

• We think there are layers because of errors in our data that we haven't been about to fix.

• Layers have different colors which affect the speed the waves travels.

• Layers have different average temperatures and composition which affects the speed the wave travels

• Layers have different depths and waves change speed as they travel further

Answer explanation

• 
• 
• 

Answer explanation

2.5.3

Which of the following best explains how the motion of the mantle leads to new crust?

• Cold spots in the mantle lead to sinking areas which pull crust down causing valleys which then need to be filled.

• Hot spots cause part of the mantle to rise and push apart old crust, creating new crust where the magma cools

• Cold spots cause part of the mantle to rise and push crust pieces together, leaving holes in which magma can cool and become new crust

• Hot spots in the mantle lead to slow moving areas which get covered up by cold spots, causing mountains.

2.5.3

What happens when the mantle pushes oceanic crust into the continental crust?

• Since the continental crust is more dense, it subducts. This crust is very dry which makes the area at this boundary a desert.

• Since the oceanic crust is more dense, it subducts. This brings sea-water into the mantle which causes the mantle to get colder and more solid.

• Since the continental crust is more dense, it subducts. This crust is very dry and gets hot as it moves so it melts into magma.

• Since the oceanic crust is more dense, it subducts. This brings sea-water into the mantle which causes a reaction and makes part of the rock melt into magma.

Answer explanation

This question links to success criteria 2.5.3: I can relate changes in the mantle to crustal plate motion and surface features on the crust.
