a type of mechanical weathering which occurs when rocks grind away at each other when they collide.
What is abrasion
100
the number one erosional agent in earth science.
What is water
100
the levels or layers of soil
What is horizons
100
List 3 out of the 5 factors that affect the formation of soil.
What is parent material, biota, climate, topography, time
100
most of the B horizon consists of this
What is clay particles
200
a type of chemical weathering which often results in rusting. Rust results because iron becomes exposed to water and oxygen in the air.
What is oxidation
200
a type of mechanical weathering that occurs because of the repeated freezing and thawing of water/ice.
What is ice wedging/frost wedging.
200
the living and organic components in a certain environment
What is biota
200
a reason that soil is so important on Earth
What is soil is necessary for life and plant growth on Earth
200
the process that causes river gravel to have rounded edges
What is abrasion
300
a type of weathering which occurs because of the physical interactions of rock in its environment. The rock is not transformed into a different substance.
What is mechanical weathering
300
a place or climate where the most weathering would occur. (Think regional)
What is warm, wet climate.
300
the rate that some is broken down into soil
What is decomposition
300
an example of organic matter that can be found in soil
What is wastes from animals, decaying plants and animals, insects, anything containing carbon.
300
the type of climate that has teh fastest rate of weathering
What is warm, wet climate
400
a type of weathering that causes rocks or parts of rock into a different substance.
What is chemical weathering
400
besides streams; the other natural elements that can cause abrasion
What is glaciation, wind and waves
400
also known as rusting, iron is particularly affected by this process.
What is oxidation
400
an inorganic substance that can be found in soils
What is rock fragments, gravel, cobbles, silt, sand, clay, water, air
400
the process of drought, land overuse, and abuse can cause this.
What is desertification
500
a type of mechanical weathering that results in the cracking, fragmentation, and fracture of rock because of plant growth.
What is root pry
500
the reason that water causes the most weathering. What water does to substances or most substances.
What is dissolve minerals.
Water dissolves most substances in natural.
500
the term that describes the general shape of the land
What is topography
500
the spaces in soil that provide pockets of air for living organisms living in the soil.
What is a pore
500
parent material in soil would most likely be found in this horizon.
