What is soil made of? rock particles, minerals, air, water, and humus
What is a soil horizon? A soil horizon is a layer of soil that is different in color and texture from the layers above or below it.
What is Horizon A (Topsoil)? a crumbly, dark brown soil that is a mixture of humus, clay, and other minerals.
What is Horizon B (Subsoil)? clay and other particles washed down from horizon A but little humus.
What is Horizon C? contains partially weathered rock
What is Bedrock? the solid layer of rock beneath the soil.
What types of decomposers are in the soil? Protists, Earthworms, Fungi, and bacteria
What is weathering? Weathering is the process that breaks down rock and other material on Earth’s surface.
What is Erosion? Erosion is the movement of broken down rock particles by wind, water, or ice.
What are the two types of weathering? Mechanical and chemical weathering
What is Mechanical weathering? Mechanical weathering is when rock is broken down physically.
What are the types of mechanical weathering? Abrasion,Freezing and Thawing,Heating and Cooling,Animal Actions, and Plant Growth
What is chemical weathering? Chemical weathering is the process that breaks down rock through chemical changes.
What are the types of chemical weathering? The agents of chemical weathering are water, oxygen, carbon dioxide, living organisms, and acid rain.
What is the rate of weathering? The type of rock and the type of climate will determine how fast something weathers.
What else is important? If the rock has a lot of holes or openings (permeable) it will weather faster. Weathering will occur faster in hot and wet climates.
True or false? Two types of weathering are chemical and mechanical? True
What is permeable? If the rock has a lot of holes or openings (permeable) it will weather faster.
When will weathering happen faster? In hot and dry climates.
