True or False: chemical weathering can change the physical shape of a rock.
True.
What 2 factors affect the rate of weathering?
Rock characteristics and climate.
What influences a water's ability to penetrate rock?
Physical characteristics of rock.
How two climate attributes affect the weathering of a rock?
Climate and rock characteristics.
What kind of climate is ideal for chemical weathering?
The climate that is best for weathering is cold and dank.
What is an important product of weathering?
An important act of product weather is soil.
True or False: All life depends on a roughly twelve elements that come from Earth's crust.
False
Define regolith.
Regolith is a layer of rock and mineral fragments produced by weathering.
What part of the regolith supports the growth of plants?
Soil is the part of regolith that supports weathering.
What are the 4 major components of soil?
Mineral matter, Broken down rock, Organic matter (Humus or decayed animals), and water. Page 133, Paragraph 3, Sentence 1.
Define mineral matter.Mineral matter is one of the four major components of soil. It also broken down rock.Define organic matter.Organic matter is humus, or decayed remains of organisms.What two ingredients are vital for all plant growth?Water and air are vital for plant growth.True or False: Most soils contain particles that are the same size.False.Soil composition consists of what four substances?Soil composition consists of parent material, time, climate, organisms, and slope.What strongly influences a soil's ability to support plant life?What strongly influences soil's ability to support plant life is the soils texture.What types of soil are usually best for plant growth?Loam soils are usually best for plant growthWhat 2 things does soil structure determine?Soil structure determines how easily a soil can be cultivated and how susceptible it is to erosion.What are the 5 most important factors in soil formation?The five most important factors in soil formation are parent material, time, climate, organisms, and slope.Explain how Parent Material impacts soil formation.Parent material impacts soil formation in two ways, it affects the rate of weathering and the rate of soil formation.Explain how Time impacts soil formation.Time impacts soil formation because the longer a soil has been forming the thicker it becomes.Explain how Climate Material impacts soil formation.Climate material impacts soil formation because variations in temperature and precipitation influence the rate, depth, and type of weathering.Explain how Organisms impacts soil formation.Organisms impact soil formation because plants are the main source of organic matter.Explain how Slope impacts soil formation.The direction of the slope affects soil formation because where the sun shines down on it. If the sun shines down on it more will grow which will change the soil formation.
