Effects of Weathering
The mechanical and chemical processes that change the objects on the Earth's surface over time.
What is Weathering?
Page 149
A mixture of weathered rock, rock fragments, decayed organic matter, water, and air.
What is soil?
Page 158
The five factors of soil formation include______,_____,______,____,_____.
What are parent material, climate, topography, biota, and time?
Page 160
______ helps estimate the amount of sand, silt, and clay in a soil.
What can be estimated by feeling the soil?
Page 163
The layers of soil formed from the movement of the products of weathering.
What are soil horizons?
Page 162
The type of weathering that physically changes the rock. (such as breaking it into pieces)
What is mechanical weathering?
Page 150
The small holes in the soil that enable water to flow through.
Whaqt are pores?
Page 158
This is made up of the rock or sediment that weathers of forms the soil.
What is parent material made up of?
Page 160
Four of the nine properties of soil are _____,_____,_____,and_____.
What are Color, texture, Structure, Consistency, Inflitration, Soil moisture, pH, Fertility, and Temperature?
Page 163
The three horizons common to most soils are _____,_____,and_____.
What are A-horizon, B-horizon, and C-horizon?
Page 162
The type of weathering that changes the chemical composition of a rock.
What is chemical Weathering?
Page 152
Overtime, roots die, and leaves and twigs fall to the ground and cause this to form.
How does organic matter form?
Page 159
They help speed up the process of soil formation.
What does biota do?
Page 161
Thsi describes how fast water inters soil.
What is Inflitration?
Page 163
The top organic layer of the soil.
What is the O-horizon?
Page 162
Ice Wedging, Abrasion, Plants, and Animals.
What are the four causes of Mechanical Weathering?
Page 151
This is known as the active skin of the earth.
What is the soil known as?
Page 158
This determines what happens to water that reaches the soil surface.
What is topography?
Page 161
Most soils have a _____ of 5.5 and 8.2.
What is pH?
Page 163
The unweathered bedrock layer of the soil.
What is the R-horizon?
Page 162
A common oxide of Earth's materials.
What is Iron oxide?
Page 153
Mechanical and Chemical weathering of rocks form this in the soil.
What is inorganic matter?
Page 159
Thease include the amount of presipitaion and the daily average annual temperatures.
What are some measures of climate?
Page 160
Thease soils are acicid and have fine ash particles.
What are the soils formed near volcanoes like?
