What effect does acid rain have on sea life?
The acids pollute the water causing sea animals to die.
100
What is the last horizon called?
Bedrock.
100
What effects mechanical weathering?
Temperatures.
100
How is soil formed?
From the weathering of rocks and minerals.
100
How are fold mountains formed?
by the uplift and folding of the tectonic plattes as they move towards eachother and collide.
200
What is acid rain?
Acid rain is wet precipitation combined with dry acid components.
200
What is a soil horizon?
A layer of soil hich is different in structure and composition from the other layers.
200
What is the most common type of mechanical weathering?
Constant freezing and thawing of water.
200
What are 2 things soil contains?
Possible answers: Rocks; minerals; dead, decaying plants and animals.
200
How are fault block mountains formed?
When tectonic plates push together and one goes up while the other goes underneath.
300
What effect does acid rain have on he air and us?
Acid rain pollutes the air causing us to have breathing problems such as asthma and lung cancer.
300
Why is horizon B considered subsoil?
It contains both rocks and soil.
300
What is mechanical weathering?
When rocks are broken down without any change in the chemical of nature of the rocks.
300
How long does the formation of soil take?
It can take 1,000 years or more
300
What is the most common type of mountains?
Fold mountains.
400
What can acid rain do to non-living things?
It can decay building materials and paint.
400
What does horizon A contain?
Plant roots, worms, fungi, and bacteria.
400
What is another type of mechanical weathering?
Salt wedging.
400
What are the inorganic matericals of the soil?
Rocks.
400
What is an example of fold mountains?
Himalayan Mountains in Asia.
500
What effect does acid rain have on the forests of the world?
The acid rain damages the waxy coating that protects the leaves which allows the acid to seep into the leaves.
500
What horizon C contain?
Weathered rock.
500
What is the most common type of mechanical weathering in deserts?
Abrasion
500
How can plants help the development of the soil?
Plants attract animals. When the animals die, their bodies decay. Decaying matter makes the soil thick and rich.

What is an example of a fault- block mountain range?
Sierra Nevada Mountains in California.
