Earth's Changing Surfaces Flashcards
Mechanical weathering
Rocks are broken apart by physical processes
Chemical weathering
Reactions dissolve the rock or change them into different materials
Erosion
The movement of sediment form one place to another
Four types of erosion
Glaciers
Gravity
Water
Wind
Deposition
Laying down of sediment that has been eroded
What are deltas and alluvial fans
Fan shaped deposits at the mouths
Meanders and oxbow lakes
Bends in a river
What are flood plains
Strip of both sides of the river that is made up of sediments
Wind blowing rocks together to form smaller rocks
Weathering
A mudslide flowing down a steep hill
Weathering
Floodwater pounding against the canyon wall and wearing it down
Weathering
Water getting into cracks, freezing and breaking the rocks apart
Weathering
Wind blowing sand from one location to another
Erosion
Brainwash him away soil from a hillside
Erosion
Glaciers scraping rocks across the earth surface
Erosion
Muddy water being carried away by fast-moving river
Erosion
Landforms Called deltas that form where rivers flow into other bodies of water such as a sea
Deposition
Layers of sediment forming at the bottom of the ocean
Deposition
Waves dropping sand on the beach
Deposition
Glaciers that drop rock sand and other debris’s forming landforms called moraines
Deposition
Two dimensional model of the earths surface
Topographic map
It connects points of egalitarian elevation
Contour line
The difference between high and low elevations
Relief
Difference in elevation between each line
Contour interval
