WEATHERING AND SOIL FORMATION!
Chapter 10By: Paula Tatum
Weathering Weathering is the breakdown of rock into
smaller and smaller pieces.
Mechanical Weathering Mechanical Weathering is simply the
breakdown of rock into smaller pieces by physical means.
Chemical Weathering Chemaical weathering is the chemaical
breakdown of rocks and minerals into new substances.
Abrasion Abrasion is the action of rock and
sediment grinding against each other and wearing away exposed surfaces
Acid Precipitation Acid Precipitation is precipitation the
contains acid to air pollution.
Oxidation Oxidation is a chemaical reaction in
which an element such as iron, combines with oxygen to form an oxide.
Differential Weathering Differential Weathering is a process by
which softer, less weather-resistant rocks wear away, leaving harder, more weather-resistant rock behind.
Soil Soil is a loose mixture of small mineral
fragments and organic material.
Bedrock Bedrock is the layer of rock beneath soil.
Parent rock Parent rock is the rock that is the source
of soil.
Humus Humus is soils that contain very small
particles of decayed plant and animal material.
Topsoil Topsoil is the top layer of soil.
Leaching Leaching is the process by which
rainwater dissolves and carries away the minerals and nutrients in topsoil.
Soil conservation Soil conservation consists of the various
methods by which humans take care of the soil.
Erosion Erosion is the process by which wind and
water transport soil and sediment from one location to another.
Summary Weathering tells the erosion, soil
conservation, leaching, soil, abrasion, Acid precipitation, oxidation, topsoil, bedrock, parent rock, humus, then it is chemical weathering, mechanical weathering, and differential weathering. Weathering makes a different in our climate, and the world we live in today.
