Weathering Erosion Dep Landforms Flashcards
Weathering
Breaking down of substances such as rock and minerals by physical chemical or biological processes
What are the three different types of weathering?
Physical or mechanical , chemical ,or biological
What is
PHYSICAL weathering???
Physical weathering is the direct contact with earths atmospheric conditions
Some examples of physical weathering
Wind,water,gravity,animals,plants roots,temperature change
What is chemical weathering?
Chemical weathering is the process by which rocks are Broken down by chemical reactions
What makes up oxidation?
Iron + oxygen + water
What is the product of oxidation??
Rust
What is biological weathering?
Breaking down from a living thing
Water is living
True or false
False
What is erosion
The movement of sediment from one location to another
What causes erosion
Water or wind or gravity
What Is deposition?
When particles carried by watered wind are dropped in another location
NO MORE WATER OR WIND
Canyons
Deep narrow valley with steep sides
Give 3 examples of deposition
- deltas
- Sand dunes
- Shells at a beach
Deltas
Landform that’s created from deposition of sediment at the mouth of a river
Give different kinds of deltas
River Dominate Delta
Tide dominate
Wave dominate
What is wave dominate deltas
Looks like a flattened triangle. The lines running across the delta are ridges that formed as the delta built up
What is a river dominate
Is something called a “bird foot “
Long narrow mounds of sediment called levees build up along the sides of the narrow distributary channels
Tide dominate
Have long and narrow offshore bars or islands at the mouth of the river such as in western Papua New Guinea
Caves
Large under ground chamber, typically of natural origin in a hillside or cliff
Sand Dunes
Landform created from the deposition of sand in large hill-like structures that are constantly changing
