Weathering
The form of physical weathering that occurs when water fills the cracks in a rock, then freezes and expands, making the cracks bigger until the rock eventually breaks
What is frost wedging?
This natural event happens when a large amount of soil is eroded all at once, sliding down a cliff or mountain.
What is a landslide?
Deposition is a factor in forming which type of rock?
What is sedimentary?
These are the three main types of soil.
What are sand, silt, and clay?
Land features such as the Grand Canyon are shaped by gradual wearing away due to this natural process.
What is (water) erosion?
The form of physical weathering that occurs when rock particles are worn away by something scraping against or hitting them.
What is abrasion?
These four elements of nature are responsible for erosion.
What are water, wind, ice, and gravity?
Deposition follows this process in the slow changes to Earth's surface.
What is erosion?
This is the component of soil that is made of the decomposing remains of formerly living organisms. It adds key nutrients to the soil to help with plant growth.
What is humus?
Land features such as the White Sands National Monument in New Mexico are shaped by gradual sediment buildup due to this natural process.
What is (wind) deposition?
The chemical that is made when carbon dioxide mixes with water, contributing to chemical weathering.
What is carbonic acid?
This landform is created by water erosion happening continuously over time, eventually cutting throught he surface of the Earth.
What is a canyon?
This landform is a result of the constructive process of deposition when sediment particles are deposited at the mouth of a river.
What is a delta?
The acronym CLORPT represents these five factors in soil dvelopment.
What are climate, organisms, relief, parent material, and time?
Land features such as the Cliff of Moher are shaped as waves break down the cliff face over time due to this natural process.
What is weathering?
The form of chemical weathering that occurs when oxygen reacts with the iron in the rocks.
What is oxidation?
This style of farming in which the land is cut into step-like platforms helps prevent erosion.
What is terracing?
This landform is a result of the constructive process of deposition when sediment particles are dropped by the wind in the same location, piling up.
What are sand dunes?
This is the topmost horizon of the layers of soil, where organic material is both living and decomposing.
What is the O Horizon?
Landforms such as the Nile Delta in the Mediterranean Sea are formed as sediment is repeatedly built up at the mouth of a river in this natural process.
What is deposition?
This type of living organism produces a weak acid that can eat away at rocks.
What is lichen or fungi?
This form of erosion occurs when humans cut down and remove large amounts of trees.
What is deforestation?
Deposition occurs when the environmental element carrying the sediment loses its __________
What is kinetic energy?
This term is another name for the C Horizon or Parent Material layer.
What is the regolith?
Land features such as Yosemite Valley are created as glaciers cut through Earth's surface in this natural process.
What is (glacial) erosion?
