A deposit of sediment that builds up at a river’s mouth.
Delta
What caused this?
erosion by water
Beaches that have eroded are reclaimed through:
beach nourishment
What caused this?
weathering
An earthquake is caused by a __________ in the rock that makes up Earth’s crust.
break
The landform in the picture
sand dune
The breaking down of rock at or near the Earth’s
surface is called:
weathering
what controlling force process is being shown?
contour plowing
An earthquake happens along a _____
fault
Are earthquakes and volcanoes constructive processes
or destructive processes?
They are BOTH constructive and destructive!
Sand, soil, and rocks are all examples
of:
sediment
The movement of weathered rock from place to place
erosion
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
What is shown in the picture?
groin
What is the hot liquid inside of a volcano called?
What is it called when it reaches the Earth’s surface?
Magma
Lava
A landform created by glaciers
moraines
What pulls pieces of rock downhill to create a landslide?
gravity
Explain the purpose of the structure
Built to hold back floodwaters at times of heavy rainfall
What is the purpose of this structure?
This storm drain prevents streets from flooding when it rains.
Devices called ______________can detect vibrations during an earthquake.
seismographs
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.
What type of erosion caused this to happen?
erosion by water/waves
Explain the purpose of the structure
Seawalls absorb the pounding of waves and protects the coast behind it
Name the two methods that farmers use to prevent soil erosion
Contour Plowing and Terracing
Explain how earthquakes are constructive processes
Earthquakes are constructive processes because they can build land along fault lines or raise mountain ranges
