Scientists observe soil to determine what plants will grow in an area. What do scientists mean when they talk about the texture of soil?
the weight of the soil
the temperature of the soil
the feel of the soil
the color of the soil
11.What is humus? What color is soil with lots of humus?
The organic material in soil; dark brown to black
Sand in the soil; dark brown to black
The organic material in soil; light tan

6.What is the difference between weathering and erosion? Give an example of each.
Weathering breaks down the rock (example: wind blowing sand). Erosion moves the broken pieces (example: a river wearing away pieces of rock).
