Constructive
a gorge
mountains
A river Valley
A canyon
The process of moving sediment by wind, moving water, or ice
Erosion
Where would you most likely find a delta?
Near a river's mouth
When water drops off sediment in a river as it travels, does the river get deeper or more shallow?
More shallow
The breaking down of rock on Earth's surface into smaller pieces
An area of new land at the mouth of a river, formed by sediments carried by the river.
Delta
What is weathering?
The process of breaking down rock by natural means
Why do sand dunes most likely form by an ocean
Water and wind can both move sand. Sand dunes form where the wind is strong and the sand deposits are plentiful. That is why the beach is the perfect location for them!
Erosion ___________ it
Deposition ___________ it
Breaks
Takes
Drops
This term describes mountains, rivers, and other SURFACE FEATURES of the land
Landforms
Name 3 types of constructive forces
Fault, Earthquake, Volcano, Deposition, Wind (Sand Dunes)
What are 3 types of weathering?
Acid Rain, Ice expanding (cracking surfaces), tree roots growing and cracking roads, wind, water
How is moving water a destructive process?
Carries away broken rock/sediment. Can break down rocks into sediment.
What does a seismograph do?
Measures the earth's vibrations to gather information about earthquakes
The process by which weathered rock is picked up and moved to a new place
erosion
This constructive force moves sediment through water until it is deposited to create a new landform
What is deposition?
Name one way humans are a destructive force on nature?
Pollution, deforestation, over crowding, carbon footprint
What is one land form made from erosion from water.
canyons, valleys, mesa, banks of a river, delta
How do plants help prevent erosion?
Their roots help hold the soil in place, and also help protect the area from wind
When erosion takes place underground, the earth above it can collapse, causing a
Sinkhole
How are sand dunes formed
The wind blows the sand and can shape hills or mounds of sand called dunes
What are two things that can be both destructive and constructive depending on the situation?
Earthquakes and volcanoes
When fast moving water runs along the banks of a river, does the river get wider or narrower?
Wider
Explain how earthquakes and volcanoes can be both constructive and destructive forces
Accept reasonable answers
The sudden movement of rocks and soil down the side of a hill because of gravity and rain
Landslide
