200
contour plowing
200
An earthquake happens along a _____
fault
200
Are earthquakes and volcanoes constructive processes
or destructive processes?
They are BOTH constructive and destructive!
300
Sand, soil, and rocks are all examples
of:
sediment
300

erosion
300
What is the purpose of a groin?
a. To strengthen dams b. To stop beach erosion
c. To create new sediment on shorelines d. To break down headlands
b. To stop beach erosion
300
What is shown in the picture?
groin
300
What is the hot liquid inside of a volcano called?
What is it called when it reaches the Earth’s surface?
Magma
Lava
400
A landform created by glaciers
moraines
400
What pulls pieces of rock downhill to create a landslide?
gravity
400
Explain the purpose of the structure
Built to hold back floodwaters at times of heavy rainfall
400
What is the purpose of this structure?
This storm drain prevents streets from flooding when it rains.
400
Devices called ______________can detect vibrations during an earthquake.
seismographs
500
How is a glacier both constructive and destructive?
Glaciers destruct the Earth by carving into canyons. Glaciers construct the Earth by dropping off sediment in various places.
500
erosion by water/waves
500
Explain the purpose of the structure
Seawalls absorb the pounding of waves and protects the coast behind it
500
Name the two methods that farmers use to prevent soil erosion
Contour Plowing and Terracing
500
Explain how earthquakes are constructive processes
Earthquakes are constructive processes because they can build land along fault lines or raise mountain ranges
