A plant's roots grow into a sidewalk, causing the sidewalk to crack and break apart
Weathering
an earthquake breaks a large piece of rock off an embankment
Weathering
Water freezes in the cracks of a boulder, breaking the crack open even further
Weathering
a flood breaks off large rocks from the banks of a river
Weathering
Heavy rains move rocks and sediments from a hillside
Erosion
Limestone rock is chemically dissolved to form a cave.
Weathering
The roots from plants keep soil in place and help prevent it from washing away. (Which agent does it help prevent?)
erosion
a sandstorm creates sand dunes on the beach
Deposition
a landslide quickly moves loose dirt and plants down a mountainside or hillside
Erosion
Wind moves sand and sediments in a severe dust storm
Erosion
Sand fences help sand dunes grow bigger, helping to prevent erosion.
Deposition
when Mt. St. Helens erupted, the peak of the mountain broke off
Weathering
a glacier moves through a mountain range, moving large pieces of rock and carving out part of the mountain
Erosion
A glacier melts and drops off sediments as it moves along its path
Deposition
Explain how a Glacier is an example of ALL THREE!
weathering-original mountain is carved away, erosion-movement of rocks and boulders; deposition: the rocks end up in a new place
a slow-moving river drops off sediments at the mouth of a river, creating a delta
Deposition
Erupting volcanoes in the ocean create new islands when the lava cools
Deposition
Cooling lava from erupting volcanoes creates more land on the islands of Hawaii
Deposition
young rivers at the top of mountains carry rocks and sediment downstream
Erosion
water cuts through a mountain, forming a canyon
Weathering
crashing waves break off rocks on a cliff at Cape Cod
Weathering
slow-moving rivers drop off sediments, creating salt marches and swamps
Deposition
Waves drop sand, creating sandbars in the middle of the ocean
Deposition
a mudslide moves rocks, plants, and sediments from the top of a mountain. (Bonus if you can you explain how it could be all THREE?
Erosion
As a river slows down, it drops off rocks and sediments along the riverbank.
