Earth's Layers & Plate Movement

Earth's Layers & Plate Movement

Multiple Choice

Which description is evidence for the theory of plate tectonics but does not suggest that the continents were once connected?

• matching rock layers on separate continents

• similar land features on separated, present-day continents

• the interlocking of present-day coastlines, such as Africa and South America

• thin layer of sediment covering the ocean floor, indicating that it was relatively young

Multiple Choice

Which processes are best explained by the theory of plate tectonics?

• life cycles of plants

• food chains and webs

• changes in air pressure

• earthquakes and volcanic eruptions

Multiple Choice

What is formed where 2 CONTINENTAL PLATES COLLIDE?

• ocean basin

• earthquakes

• mountains

• volcano

Multiple Choice

What is formed where these plates are spreading apart?

• new ocean floor

• earthquakes

• volcanoes

• mountains

Multiple Choice

What causes the majority of earthquakes to happen?

• rocks moving downward

• rocks along transform boundaries moving suddenly

• convection currents

• rocks moving miles away from a divergent boundary

Multiple Choice

Which of the following would be the best description of a divergent boundary?

• When two plates push together, colliding on impact.

• A denser plate subducts under a less dense one.

• A space is created between two plates as they move apart.

• When oceanic plates collide, one subducts under the other to form a deep valley.

Multiple Choice

Which of the following is the best description of a convergent boundary?

• Boundaries form where plates move away about convection currents

• Plates move apart, becoming stretched and thin

• A space is created between two plates as they move apart

• When two oceanic plates converge and collide, the denser plate will subduct beneath the less dense one.

Multiple Choice

This layer of Earth is solid Iron and Nickel

• Outer Core

• Mantle

• Inner Core

• Crust

Multiple Choice

Earth's plates are...

• constantly moving and changing the face of the earth

• Never moves

• Moves seldom and very fast

• Moves when it feels like it

Multiple Choice

Name the boundary

• convergent boundary
• divergent boundary
• transform boundary
• sergent boundary

Multiple Choice

Name the boundary

• convergent boundary
• divergent boundary
• transform boundary
• sergent boundary

Multiple Choice

In some places on Earth, large tectonic plates are moving toward each other and collide with great force. One such place is where the Indian plate and the Eurasian plate meet.

What would you expect to occur where these two tectonic plates collide?

• Only volcanoes

• Only earthquakes

• A rift valley and volcanoes

• Mountains and earthquakes

Multiple Choice

The Atlantic Ocean is growing in size by about one centimeter per year. How does an ocean become larger?

• Oceanic plates are moving apart.

• The density of the oceanic plates is decreasing.

• Increased air temperatures are increasing evaporation.

• Trenches are formed by oceanic plates sliding under continental plates.

Multiple Choice

Which layer of the Earth has convection currents that cause tectonic plates to move?

• Crust
• Mantle
• Outer Core
• Inner Core

Multiple Choice

What happens to temperature as you move down through the layers?

• it remains the same

• it increases then decreases

• it increases

• it decreases

Multiple Choice

Which layer of the earth has the lowest temperature?

• Crust
• Mantle
• Outer Core
• Inner Core

Multiple Choice

Which layer of the earth is between the core and the crust?

• Crust
• Mantle
• Outer Core
• Inner Core

Multiple Choice

What is the correct order of Earth's layer starting from the surface?

• Crust, mantle, outer core, inner core

• outer core, inner core, crust, mantle

• crust, outer core, inner core, mantle

• mantle, outer core, inner core, crust

Multiple Choice

Why is the inner core made of solid metal?

• Because it is so hot it turns from liquid to solid
• Because of the weight of the crust
• Because of it's temperature
• Because of the pressure of the other layers beating down on it

Multiple Choice

What are the two types of crust?

• Continental and Landforms
• Oceanic and Mountains
• Mountains and Landforms
• Oceanic and Continental
