Unit Review: Earth's Structure, Plate Tectonics, Rock Cycle

Reorder

Arrange the following steps in the correct order to show how plate movements are linked to the formation of new rocks:

• The tectonic plates move apart from one another.

• Magma forms beneath the plates and rises up through the cracks.

• Lava flows onto Earth's surface.

• Lava cools and hardens to form igneous rock.

Multiple Choice

What process does the figure show occurring in the mantle?

• Hot rock expands, becomes less dense, and rises toward the surface of Earth

• Hot rock expands, becomes more dense, and rises toward the surface of Earth.

• Hot rock becomes less dense and moves towards the outer core.

• Hot rock becomes more dense and moves towards the lithosphere.

Multiple Choice

How does the motion of the liquid outer core affect the Earth?

• Creates earthquakes

• Generates Earth's magnetic field

• Causes volcanic eruptions

• Regulates climate

Multiple Choice

What is the role of the asthenosphere in relation to tectonic plates?

• It is a rigid layer

• It is a softer layer beneath the lithosphere

• It is made of tectonic plates

• It does not affect tectonic plates

Multiple Choice

Why are similar fossils found all over the world?

• The animals swam to new parts of the world before going extinct

• The land masses were once connected

• The organisms were transported to different areas of the world

• They are not similar fossils.

Multiple Choice

Sea-floor spreading explains how.....

• new crust is created at a divergent boundary

• volcanoes are formed on continents

• deep sea trenches are formed

Multiple Choice

What does the theory of plate tectonics explain?

• Earthquakes

• Weather patterns

• Ocean currents

• Solar system formation

Reorder

Step 1 and 5 are given to you...but you must order the middle steps correctly!

• STEP 1

  Heat from the outer core warms mantle rock!

• Plumes of mantle rock rise slowly towards the crust!

• The hot mantle rock slowly cools as it approaches the crust!

• The cooled rock sinks back down through the mantle!

• STEP 5

  The process begins again!

Multiple Choice

Which model is depicting a divergent boundary between two plates?

• top

• middle

• bottom

Multiple Choice

Oceanic and continental convergent plate boundaries form

• mountains and mountain ranges

• volcanoes and mountains

• deep-oceanic trenches and volcanoes

• island arcs, trenches, and mountains

Multiple Choice

Convergent boundaries are when plates move toward one another and collide. How are convergent boundaries involved in geological events such as volcanoes?

• When oceanic crust slide past each other without tearing or crushing each other, a volcano forms on the crust away from the plate boundary.

• When oceanic crust slide past each other without tearing or crushing each other, a volcano forms on the crust near the plate boundary.

• When oceanic crust move under a continental crust, a volcanic mountain range forms on the crusts near the plate boundary.

• When oceanic crust is forced over a continental crust, a volcanic mountain range forms on the crusts away from the plate boundary.

Multiple Choice

What are the features created by oceanic-oceanic convergent boundaries?

• Deep ocean trenches

• Mountain ranges

• Deserts

• Plateaus

Multiple Choice

What geologic feature/event would you most likely to find at a divergent boundary between two pieces of oceanic crust?

• Rift Valley

• Mid-Ocean Ridge

• Island Arc

• Flat land

Multiple Choice

What structure is the arrow pointing to?

• Subduction zone

• Stratovolcano

• Mid-ocean ridge

• Pangea

Multiple Choice

Associated with transform boundaries.

• Volcanoes
• mountains
• trenches
• earthquakes

Multiple Choice

Where are earthquakes MOST LIKELY to occur?

• close to the equator

• close to the center of tectonic plates

• at divergent or convergent plate boundaries

• at transform plate boundaries

Multiple Choice

What happens at convergent boundaries?

• Magma rises to fill gaps

• Subducting plates melt and create magma

• Plates move apart

• Hot spots form

Multiple Choice

What is the main reason the Ring of Fire has so many volcanoes?

• It is near the equator

• It is a popular tourist destination

• It is located along tectonic plate boundaries

• It has a lot of forests
