Weathering Flashcards
What is denudation
It’s when rocks on the earths surface are constantly being worn down by a number of processes
What r 2 main processes in denudation
Weathering and erosion
What is weathering
Weathering is a process taht physically changes solid rock into smaller pieces or sediments
What r 3 types of weathering
Mechanical weathering chemical weathering and biological weathering
What is erosion
Erosion is the process that breaks down and moves the sediment away from the original positions
What is mechanical weathering
Mechanical weathering is teh physical breaking down of stocks into smaller pieces
What is free thaw action
Freeze thaw action is when water gathers I the cracks in rocks during the day and at night whe it drop below 0° the water freezes an becomes ice the ice expands and after repeated dresses and thawing the rock becomes scree
What is scree
Scree is the tiny rocks after repeated dmfreezing and thawing
What is chemical weathering
Chemical weathering is causes by chemical changes when rock is dissolved or decayed
What is an example of chemical weathering
Carbonayion
What is a least landscape
It is an area made up of limestone
What are clints
Clints are the slabs of rocks exposed to the surface
What r grikes
They are the deep grooves inbetweeners clints
What is a swallow hole
It is when a river enters a karat landscape and it can disappear underground throught grikes zthe grikes become enlarged and form big vertical holes known as swallow holes
What are stalactites
Stalactites are the carbonic acid drips through the roof and leaves tiny deposits of calcite the form stalactites
