WEDGL Vocab Set #1
Terms in this set (30)
The breaking down of rocks and other materials on the Earth's surface.
The type of weathering in which rock is physically broken into smaller pieces
the process by which rocks break down as a result of chemical reactions
Frost Action/Ice Wedging
A type of physical weathering resulting from water getting in the cracks of rocks, freezing and expanding therefore; causing the rock to break or crack even more.
plant and animal action
plants/roots will grow into cracks in rocks
causing them to split as they grow
The grinding away of rock by other rock particles carried in water, ice, or wind. Breaks off sharp edges and rounds out particles in water
The most chemical Weathering Happens in this environment
Warm & Moist
A chemical change in which a substance combines with oxygen, as when iron oxidizes, forming rust
a very weak acid formed in solution when carbon dioxide dissolves in water. Causes limestone to dissolve and creates caves
Rain containing acids that form in the atmosphere when industrial gas emissions (especially sulfur dioxide and nitrogen oxides) combine with water.
A mixture of mineral particles and organic material that covers the land, and in which terrestrial plants grow.
the process by which water on the ground surface enters the soil
water that fills the cracks and spaces in underground soil and rock layers
water that flows over the ground surface rather than soaking into the ground
the volume of open spaces in rock or soil
Ability of rock or soil to allow water to flow through it
capillarity (capillary action)
the rising of water against gravity, as when water rises above the water table in soil because of the attraction between the water and the soil. Happens most in soil with small particles
The ability to keep water in soil
Completely full of water
How much area is exposed on the surface of an object. The higher it is, the faster the weathering
Rich, dark organic layer of soil material formed by decay of matter, essential to soil's fertility
Soil that remains above its parent rock
Soil that has been moved away from its parent material by water, wind, or a glacier.
Not formed from living things or the remains of living things
The upper level of the saturated zone of groundwater
If the size of a particle increases and all particles are uniform, porosity
stays the same (less number of spaces, but bigger spaces)
Release of harmful materials into the environment
Impassable, not allowing passage through (such as by a liquid)
A material that contains less than the maximum amount of solution it can hold
the speed of an object in a particular direction
