Weathering occurs due to these.
Water
Wind
Ice
a broad, C-shaped curve in a stream
Meander
the remains of something that was once alive
Organic Matter
This is a mixture of weathered rock, rock fragments, decayed organic matter, water, and air.

Examples of Erosion by Mass Wasting
landslide
rockslide
slump
creep
These erode Earth's surface as they slide over it

The 3 factors that affect weathering rates.
Environment
Type of Rock
Size and Number of Holes in Rock
The sources of acid forming chemicals that produce acid rain.
Volcanoes
Sulfur Oxide
Rushing water in stream erosion carves this shape valleys.
V
the grinding away of rock or other surfaces by erosion
Abrasion
the removal of weathered material from one location to another
Erosion
A rock’s surface area that is exposed to the environment determines this.
Rate of Weathering
Iron oxide is a common oxide of Earth Materials also called this.
Rust
This dissolves and washes away limestone in a cave eventually forming stalagmites and stalactites.
Acidic Groundwater
a large mass of ice that formed on land and moves across Earth’s surface
Glacier
