What is a rock?. A rock is a naturally occurring solid mixture of one or more minerals or organic matter.
The Nature of Soil Chapter 7, Section 2. The Formation of Soil What is Soil? Mixture of weathered rock, decayed organic matter, mineral fragments, water,
G2-2 Soil Formation and Composition EQ: How do you scientifically describe soil? How is soil formed?

Soils: One of Our Natural Resources!. Some call it dirt…..But it is Soil !!! Soil is made of loose, weathered rock and organic material.
WEATHERING AND EROSION Rock Cycle WEATHERING I. Weathering - The breakdown of rock due to exposure to the atmosphere, weather, plants, and animals.
Types of Weathering Chemical Mechanical Agents of Weathering Rainwater Oxygen Carbon dioxide Plant decay acids These are all examples of chemical erosion.
Science Terms. Topsoil The uppermost layer of soil Top Soil.
Soil. the top layer of the earths surface, consisting of rock and mineral particles mixed with organic matter.
Soil. organic the top layer of the earths surface, consisting of rock and mineral particles mixed with organic matter.
SOIL Soil provides support and nutrients for plant growth.
Earth Science- Environments Scientific Question of the Day.
Soil Characteristics. Soil a layer of natural materials on the earths surface containign both organic and inorganic materials and capable of supporting.
Rocks and Weathering EQ: What is chemical and mechanical weathering?
Weathering This week we write it down if its in ORANGE. Photo: Grand Canyon, National Park Service.
Soil The product of weathering of rocks Soil is made from rocks, minerals (mainly sand and clay), and organic material. Soil forms layers of different.
1. What is the process called in which rocks break down? 2. What do we use to determine the hardness of a mineral? 3. How are rocks categorized? 4. What.
