4.

• causes the most erosion on earth.

weathering and earth’s surface

• tectonics builds mountains.
• weathering and erosion slowly mountains over time.
• the mountains were once as tall as the himalayas.

mechanical weathering (physical weathering)

• mechanical weathering breaks rocks into pieces.
• the rock’s does not change.

types of mechanical weathering
ice wedging

• water freezes in cracks, , and breaks rock apart.
• common in places that and thaw.

abrasion

• rocks into each other.
• makes rocks and rounded.

biological weathering

• plant grow into cracks.

Explanation:

This is a fill - in - the - blank worksheet about weathering and erosion, which belongs to the field of Geography (a subfield of Natural Science). To answer these blanks, we can use the following knowledge:

What Is Weathering?

• Weathering is the breakdown of rocks into smaller pieces (either physically or chemically) at or near the Earth's surface.

What Is Erosion?

• Erosion is the process that moves sediments from one place to another.
• The four forces of erosion are:

1. Water
2. Wind
3. Ice (Glaciers)
4. Gravity

• Water causes the most erosion on Earth.

Weathering and Earth's Surface

• Plate tectonics builds mountains.
• Weathering and erosion slowly wear down mountains over time.
• The Appalachian Mountains were once as tall as the Himalayas.

Mechanical Weathering (Physical Weathering)

• Mechanical weathering breaks rocks into smaller pieces.
• The rock’s chemical composition does not change.

Types of Mechanical Weathering

Ice Wedging

• Water freezes in cracks, expands, and breaks rock apart.
• Common in places that freeze and thaw.

Abrasion

• Rocks collide into each other.
• Makes rocks smooth and rounded.

Biological Weathering

• Plant roots grow into cracks.
