Study Guide for Thursday's Test

Which layer of Earth does this describe? 

NOT MULTIPLE CHOICE

 1. This layer is the solid outer part of the Earth. 

2.  This layer is comprised of the crust and the upper mantle.

3.  This layer lies above the asthenosphere

4. This layer is made of rock that is cooler and stronger than the other layers.

• asthenosphere

• outer core

• lithosphere

• upper mantle

Which of these is the thickest layer of the Earth?

• crust

• mantle

• outer core

• inner core

What is layer C in the diagram of Earth?

• asthenosphere

• mantle

• outer core

• inner core

How are the crust and the inner core ALIKE?

• they are both solid

• they both have the same temperature

• they both have the same pressure

• they are both rocky

Look at the diagram. What will be the result of a continental-continental convergent boundary with a subsurface process such as this?

• The material of the asthenosphere merges with the 

  lithosphere,forming a fault line.

• When the plates collide, the lithosphere will crumble, 

  forming a deep rift in the ocean floor.

• The continental crust on both sides of the plates will squeeze together, forming a ridge.

• The continental crust will merge with the lithosphere at the area where the plates collide, becoming one layer.

How does the temperature of the Earth’s mantle compare to the other layers of the Earth?

• the mantle is hotter than the core

• the mantle is hotter than the crust

• the mantle is the same temperature as the core

• the mantle is the same temperature as the crust

An oceanographer is exploring seafloor spreading. She wants to learn more about how igneous rock is formed deep in the bottom of the ocean. Which type of plate boundary should the oceanographer study in order to understand seafloor spreading?

• an area where one plate slides underneath another plate

• an area where two plates pull away from each other

• an area where two plates collide, creating upthrust

• area where two plates slide past each other

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

• conduction

• convection

• insulation

• radiation

The dots on the map represent volcanoes and Earthquakes, or the Ring of Fire. What causes this change in the Earth’s surface?

• That part of the ocean has a 

  high rate of hurricanes and 

  typhoons.

• That part of the ocean is 

  directly above the boundaries 

  between tectonic plates.

• An increased number of tsunamis in the Pacific led to an increase in earthquakes.

• There is pressure on the seafloor due to the weight of water of the Pacific Ocean.

Scientists use models to investigate processes which happen too slowly, or quickly, or too small or large scale to be observed directly. 

Which of these statements describes a benefit of using a computer model to simulate interactions in Earth's layers?

• The model allows scientists to more reliably prevent the motion of tectonic plates. 

• The model allows scientists to more directly observe the motion of tectonic plates.

• The model allows scientists to more carefully change the motion of tectonic plates.

• The model allows scientists to more accurately predict the motion of tectonic plates.
