Weathering & Erosion 2.1.3

How do rocks become sediments?

• melting

• weathering

• cooling

• pressure

Erosion is...

• materials begin moved across the Earth's surface by water and wind
• materials deposited into a new location as sediment
• rocks and other materials being broken down both physically and chemically

When rock goes through weathering and erosion what forms?

• Sediment

• Magma

• Lava

• Boulders

What is the moving of sediment by wind, water, or gravity?

• Mechanical weathering

• Chemical weathering

• Erosion

• Compaction

These rocks were made smooth by wind blowing smaller rock particles across their surface.  This is an example of:

• ice wedging
• chemical weathering
• acid rain
• abrasion

These rocks were broken apart from the continuous freeze/thaw of water in the cracks of the rocks. This is an example of:

• ice wedging
• acid rain
• permeability
• abrasion

This rock may chemically weather easily because is has many spaces or holes in it that allow water to seep through it, meaning it is:

• permeable
• abrasive
• erosion
• unchangable

Weeds growing into the cracks in a sidewalk and the sidewalk begins to crumble is an example of:

• mechanical weathering
• chemical weathering

Deposition is a process that ______________.

• Dissolves sediment
• Removes sediment from landforms
• breaks down rock to form sediment
• drops sediment to form landforms

The process that breaks down rocks and other materials on Earth's surface is called

• Weathering
• Erosion
