Test Description: Physical and Chemical characteristics of soil layers. The factors that affect soil formation, including the action of living things.
Instructions: Answer all questions to get your test result.
1) Gopher tortoises live on dry land. They live in large holes that they dig in the soil. Which statement gives the best explanation of how this behavior aids in soil formation?
A
It does not aid in soil development.
B
t hardens the soil, allowing less water to reach the rocks underground.
C
It loosens and mixes the soil, increasing air in the soil and the ability to drain water.
2) Which of the following describes how microorganisms (bacteria) influence the characteristics of soil?
A
They add inorganic material to the soil by weathering rocks on Earth's surface.
B
They loosen and mix the soil by digging burrows underground.
C
They add organic material to the soil by breaking down the remains of plants and animals.
D
They add moisture to the soil by creating pores through which water can move.
3) What is soil?
A
a loose mixture of rock fragments/minerals, organic matter/material, water, and air that can support the growth of vegetation
B
weathered sediment broken down by atmospheric forces on Earth's surface
C
dark, organic material formed in soil from the decayed remains of plants and animals
D
spaces between soil particles through which water and air can move
4) What is humus?
A
a loose mixture of rock fragments/minerals, organic matter/material, water, and air that can support the growth of vegetation
B
dark, organic material formed in soil from the decayed remains of plants and animals
C
spaces between soil particles through which water and air can move
D
weathered sediment broken down by atmospheric forces on Earth's surface
5) What is pore space?
A
a loose mixture of rock fragments/minerals, organic matter/material, water, and air that can support the growth of vegetation
B
spaces between soil particles through which water and air can move
C
weathered sediment broken down by atmospheric forces on Earth's surface
D
dark, organic material formed in soil from the decayed remains of plants and animals
6) In which of the following locations is new soil likely to form at the slowest rate over time due to environmental conditions?
A
hillside
B
forest
7) Granite has only recently been exposed at a location on the Earth's surface. What will need to happen first in order for soil to eventually form in this location?
A
Erosion by wind and water must move pieces of granite to other locations.
B
The granite must be broken down into smaller pieces by weathering processes.
C
A thick layer of humus must form on top of the granite.
D
Microorganisms must begin to break down the remains of plants and animals.
8) What materials are necessary for soil to form?
A
organic matter
B
air and water
C
all of these
D
small rock fragments
9) What is the first stage in the development of soil?
A
Bedrock begins to disintegrate/break down.
B
Horizons begin to form.
C
Developed soil supports thick vegetation.
10) What is the second stage in the development of soil?
A
Developed soil supports thick vegetation.
B
Bedrock begins to disintegrate/break down.
C
Horizons begin to form.
