Weathering
The mechanical and chemical processes that change objects on 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 starting material of soil.
What is parent material?
Page 160
Characteristics used to describe something.
What are Properties?
Page 163
These five factors contribute to soil formation.
What are parent material, topography, climate, biota, and time?
Page 165
The physical processes that naturally break rocks into smaller pieces.
What is mechanical weathering?
Page 150
The remains of something that was once alive.
What is organic matter?
Page 158
The shape and steepness of the landscape.
What is topography?
Page 161
This property can be measured by feeling the soil.
What is texture?
Page 163
Inorganic matter is made up of this material.
What is weathered parent material?
Page 165
Is the change in a material that are part of a rock into new materials.
What is chemical weathering?
Page 152
Small holes and spaces.
What is pores?
Page 158
All of the organisms that live in a region.
What is a biota?
Page 161
This property can be determined by the density of the soil.
What is consistency?
Page 163
Organic matter is made up of this material.
What is decomposed matter that once was living?
Page 165
Combines the element with other elements or molecules.
What is oxidation
Page 153
The process of changing once living material into dark colored organic matter.
What is decomposition?
Page 159
Layers of soil formed from the movement of the products of weathering.
What is a Horizons?
Page 162
This property can be determined by how acidic the soil is.
What is pH?
Page 163
Soil contains these.
What is horizon layers?
Page 165
The amount of space on the outside of an object.
What is surface area?
Page 150
Describes materials that have never been alive.
What is inorganic?
Page 159
The horizon layer that is mostly parent material rock.
What is the C-horizon?
Page 162
These are the most important things a plant needs.
What is water, Sun, and nutrients?
Page 163
These horizon layers are made by.
What is the movement of weathered material?
