The removal and Transport of weathered Materials by natural agent
What is erosion?
100
Process by which rocks are broken down due to exposure to processes occurring at the Earth's surface.
What is weathering?
100
This phenomenon leads to the formation of metamorphic rocks.
What is heat and pressure?
100
One of these 4 factors does NOT affect soil formation: 1. type of rock 2. time of exposure 3. surface area 4. animal intrusion.
What is animal intrusion?
100
This is the process when water and sediments flows over boulders, as shown in picture A in Ohiopyle State Park, Pennsylvania.
What is Hydraulic abrasion?
200
The five ways that erosion occurs on the Earth's surface.
What is running water, waves, wind, gravity and glaciers?
200
The 2 G's and 3 W's: the 5 causes of weathering on Earth.
What is gravity, glaciers, water, wind, waves?
200
Extrusive rocks are formed on this layer of the Earth.
What is Earth's surface?
200
The smallest of these 5 sediments: 1. sand 2. pebbles 3. clay 4. cobbles 5. boulders
What is clay?
200
Daily double! This type of process creates landforms that resemble arches, similar to the one shown in Picture B from Arches N.P.
What is wind abrasion?
300
Moving water is a natural cause of this.
What is soil erosion?
300
Rock is broken down into smaller pieces of the same material.
What is mechanical physical weathering?
300
Sedimentary rocks are often found in this type of formation.
What is layers?
300
Includes loose weathered rock, and organic material in which plant roots can grow.
What is soil?
300
This is how the Grand Canyon formed.
What is carved out by the Colorado River?
400
Glaciers account for about this percentage of the fresh water on Earth.
What is 75%?
400
The breakdown or decomposition of rock that occurs when minerals are changed into different substances.
What is chemical weathering?
400
This characteristic helps identify nonfoliated metamorphic rocks.
What is lack of distinct bands or layers?
400
This layer of soil has little or no humus.
What is the C horizon?
400
This type of weathering causes the formation shown in picture C, of Bryce Canyon, Utah.
What is chemical weathering?
500
Striations on rock is caused by this.
What is glacial movement?
500
Gradual peeling of layers due to uplift and frost action, typical of granite domes like those in Yosemite N.P.
What is exfoliation?
500
After transforming to sediment, the metamorphic rock transforms to sedimentary rock by this process.
What is cementation and compaction?
500
These sediments make up the C horizon.
What are boulders, cobbles and pebbles?
500
These can carve out mountains.
What are glaciers?
