Identify the Landform
What force made it?
Plate Tectonics
Potpourri
100
What can be caused when an earthquake occurs below the ocean?
A tsunami
100
The triangular shaped and often fertile area where a river flows into a larger body of water.
A Delta.
100
Which force carves away rocks at the beach?
Wave erosion
100
Which layer of the earth is broken up into tectonic "plates" or large pieces?
The Earth's crust
100
What is the name of a person who studies earthquakes? Name one tool that they may use to help them study.
Seismologists; Shake table, or seismograph
200
When water erodes soft rock under the ground and makes a cave, this can lead to the formation of a ______.
sinkhole
200
This landform is caused by wind moving sediments and usually occurs in very dry areas.
Sand Dunes
200
What constructive force and what destructive force is demonstrated by a flowing river?
Erosion is a destructive force and deposition is a constructive force.
200
What is happening to the plates when an earthquake occurs?
The plates catch against one another and then release quickly at a transform boundary.
200
Explain how a jetty can help protect a beach.
Jetties are built so that there is less beach erosion caused by waves.
300
Use the words volcano, lava, and magma in the same sentence. How do volcanoes create new mountains?
Sentences will vary. Volcanoes create new mountains when the lava hardens into new rock.
300
Name 2 landforms that can be created when tectonic plates move apart.
Volcanoes and trenches
300
What are the 3 forces that can make mountains rounded and smaller?
Glaciers, rain erosion, and snow erosion.
300
Name the three types of plate boundaries and use your hands to show how they move.
Divergent boundaries- move apart. Convergent boundaries- move together. Transform boundaries- slide against each other in opposite directions.
300
Choose ONE force and explain how it is both constructive and destructive.
Mrs. Harris will decide if you're right!
400
Explain the difference in WEATHERING and EROSION.
Weathering is when rocks are worn away, but erosion is moving sediment (or the pieces that are worn away) by water, wind, or ice.
400
Give one reason that some mountains are high, rocky, and jagged while others are smaller and rounded.
High and jagged mountains are typically not as OLD as small and rounded mountains. Smaller mountains have had more time to be eroded by rain, snow, and glaciers.
400
What is the difference between the effects that plants can have on rocks and soil?
Plant roots can be used to stop the erosion of soil because they hold the soil together. Plant roots can cause the erosion of rocks because the roots break up the rocks as they grow.
400
Name the type of plates that are typically thicker and slide OVER other plates.
Continental, or land, plates
400
Chains of mountains (formed from volcanoes) are typically found over __________.
Hot Spots
500
Explain the difference in a dam and a levee.
A dam is built across a river to control flooding. Levees are walls built on either side of a river to control the flow of the water and flooding.
500
Name 3 different types of volcanoes. HINT: We learned about them through our Volcano explorer activity online.
Stratovolcanoes, Cinder Cone, and Shield Volcanoes.
500
Explain 2 different ways that mountains can be made.
Volcanic eruption and convergent plate boundaries.
500
Name 4 different landforms that can be created by moving plates at plate boundaries.
Trenches, Mountains, Volcanoes, and Cliffs
500
Over many years, rivers become wider. Explain how this happens.
Rivers become wider because the water erodes the banks of the river over time.
