Wearhering And Erosion Flashcards
What is Denuatation
Denutation is the process of lowering Earths land surface through weathering and Erosion
What three categories is weathering grouped on
Chemical
Mechanical
Biological
Types of Mechanical weathering
Freeze - thaw action
Exfoliation
What is latitude
The distance from north to south from the equator
What is altitude
Height above sea level
Define weathering
Weathering it’s the breakdown of rocks, soil and materials to exposure to weather (rain frost ice snow and organisms).
Steps of freeze for action
One by day ; During the day order keeps joints cracks in the rock
Two by night: the temperature drops below freezing .0°C. The water freezes and expanse. This makes a crack bigger and put strain on the rock.
Tree: after repeated freezing and throwing of water over many years the rock split sharp, jagged pieces called scream right off they’re well down the mountain and collect in piles on the bottom of the slope

What is Limestone pavement
Limestone pavement is created when glaciers strip away soil, exposing limestone. Rainwater dissolves the rock, forming grooves called grime and flat slabs called Clints e.g the Bureen
3 advantages of tourism in the Burrwn
Economic : many direct and indirect jobs are formed near by due to the amount of tourists .
Social: out migration of locals is reduced as spin of jobs are created in arts, crafts and wellness industries .
Environmental strict planning laws within the Geo park prevent over and protect the natural beauty of the area.
three disadvantages of the Burren
Economic: some jobs are seasonal running from April to September with the most tourists visits.
Social: Houses have increased in price for holiday homes making locals have to move because they are too expensive.
Environmental: Traffic from Cars and buses at popular attractions like the cliffs of Moher is a major issue with Co2 emissions lowering air quality.
What happens when calcium bicarbonate evaporates
When calcium bicarbonate evaporates it turns into calcite.
What causes biological weathering
Lichen is an organism of a fungus and alga, it causes biological weathering, growing on rocks and producing chemicals that break down (dissolve) the earths surface.
Karts landscape
Karts is an area if exposed limestone formed by glacial ion. Its features are formed due to carbonation
