Inv 1.1
What particular place and landform are we focusing our Earth History study on
Grand Canyon
A carbonate material with the chemical formula CaCO3
calcite
The process of matching up rock layers from different locations
correlation
particles that are smooth and slick; smaller than sand and silt, it is difficult to see just one
clay
the settling of sediments
deposition
A natural feature of Earth's surface with a characteristic shape
Landform
the vertical distance of the land's surface above sea level
elevation
a thickness or bed of weathered rock material
layer
a solid earth material that is made of minerals
rock
The different rates at which layers or weathered earth materials are carried away by water, wind or ice
differential erosion
An object that orbits a planet or other planets, taking aerial images
Satellite
a sedimentary rock made mostly of calcite
limestone
a scientist who studies earth
geologist
rocks that are smaller than gravel but bigger than silt
sand
the carrying away of weathered earth materials by water, wind or ice
erosion
Who discovered the Grand Canyon
John Wesley Powell
a sedimentary rock made of sand particles stuck together
sandstone
a natural feature of earth's surface with a characteristic shape.
landform
rocks that are smaller than sand but bigger than clay
silt
a representation of something else
model
Name at least 10 landforms
alluvial fan, delta, meander, canyon, sand dune, canyon, mountain, floodplain, plain, beach
a sedimentary rock made of clay or silt
shale
Why do there appear to be stripes on the walls of the Grand Canyon
The stripes are actually edges of different types of rocks, stacked in layers on top of each other
a process by which particles are separated out from water, wind, or ice by size, shape or density
sorting
a material that is deposited by water, wind or ice
sediment
