Constructive Processes
A deposit of sediment that builds up at a river's mouth.
What is a 'Delta'?
Erosion could not happen without this force.
What is "gravity"?
the process in which beaches that have eroded are reclaimed (rebuilt)
What is "Beach Nourishment" or "Sand Dredging"?
An earthquake is caused by a __________ in the rock that makes up Earth’s crust.
What is a "break"?
What are "convergent boundaries"?
A mound of sand piled up by the wind.
What is a "sand dune"?
The breaking down of rock at or near the Earth’s surface is called:
What is "Weathering"?
this is used to prevent flooding
What is a 'storm drain'?
Are earthquakes and volcanoes constructive processes or destructive processes?
They are BOTH constructive and destructive.
these types of boundaries move apart to form volcanoes
What are "divergent boundaries"?
Deposited material; a mixture of rocks and sand.
What is "sediment"?
The movement of weathered rock from place to place.
What is "Erosion"?
this is used to hold back floodwaters at times of heavy rainfall
What is a "dam"?
What is the hot liquid inside of a volcano called? What is it called when it reaches the Earth’s surface?
What is 'Magma'? What is 'Lava'?
these types of boundaries pass one another to create earthquakes
What are "transform boundaries"?
Name a landform that is created by glaciers; these are left behind ridged of sediment and rock
Moraine
gravity causes erosion by pulling rocks downhill
What is a "landslide"?
this structure absorbs the pounding of waves and protects the coast behind it
What is a 'Seawall"?
Devices called ______________ can detect vibrations during an earthquake.
What are "Seismographs"?
where are earthquake happens
What is a "Fault?"
Explain how a glacier is both a constructive and destructive process
Glaciers destruct the Earth by carving into canyons. Glaciers construct the Earth by dropping off sediment in various places.
name two landforms that are created due to erosion by water
What are "Channels and Valleys".
name the two ways farmers prevent soil erosion
What are "terracing" and "contour plowing"?
Explain how earthquakes are constructive processes
Earthquakes are constructive processes because they can build land along fault lines or raise mountain ranges.
Name the four layers of the Earth.
Crust, Mantle, Outer Core, Inner Core
