Investigation 1 Vocab
A v-shaped landform eroded by a river
Canyon
Moving or pushing sediments by water or wind
Erode
This type of weathering breaks down rocks without changing what the rock is made out of
Physical weathering
Erosion can occur by using these two natural forces
Water or wind
A person who studies the earth's surface is called a...
Geologist
A nature feature of earth’s surface
Landform
Separating rocks based on their shape and size
Sort
This type of weathering happens in really polluted places when nitrogen and sulfur dissolves in water
Acid Rain
Erosion pushes earth materials such as sand, rock, pebbles, clay, etc. Another word for earth materials is __________
Sediments
What are the three types of rocks we learned about in Earth History?
Shale, sandstone, and limestone
The mineral that is found in limestone and in chalk
Calcite
Grinding and bumping of rocks
Abrasion
Describe root wedging
When plants grow in between cracks of rocks to push them apart from each other
What type of sediments are deposited first in erosion?
The heaviest or biggest sediment
Why does limestone fizz when acid is placed on it?
Limestone contains the mineral calcite
The thickness of the different rocks or weathered materials stacked on top of each other
Layer
The process of breaking down of sediments or rocks
Weathering
Describe frost wedging
Water getting into cracks, which freezes and expands to break apart rocks
Why are smaller and lighter sediments deposited farther?
They are lighter and can be easily be pushed by wind or water
This is the vertical distance of a land’s surface compared to sea level
Elevation
Lining up rocks at the Grand Canyon. Also, to find a relationship between two or more things
Correlation
The pure substance(s) that rock is made out of
Mineral
This type of weather grinds and bumps rocks into one another
Abrasion
Why do we need a model for erosion
Erosion takes a long time, it's too big to see, too expensive, too far away, etc.
What are the two processes that helped create the Grand Canyon?
Erosion and weathering
