Mechanical weathering
What is another name for Mechanical weathering?
Physical weathering!!!!!
Is biological weathering chemical or physical?
Trick question! It can actually be involved with both chemical and physical weathering.
Carbonation can create....
CAVES!!
Ice wedging is the process that....
Ice wedging happens when water seeps into the cracks of rocks and freezes. The water freezes, and the cracks expand further into the rock and break the rock up more. The ice pushes against the side of the rock causing the crack to expand. This process can repeat multiple times.
Plant seeds fall into rocks, and eventually grow in the rock. Over time as the tree and the roots grow the roots will split apart the rock. This process is called.....
Root wedging!!!
Oxidation is a process where oxygen reacts with what inside the rocks?
Iron!
Abrasion is the process that.....
Abrasion happens when pebbles, sand, or other rocks scrape and rub up against other rock causing them to wear away.
What is an example of biological weathering involving animals?
An example of this could be when animals burrow and create holes by moving the rock and sediment away from its original spot.
This process occurs when rainwater mixes with sulfur dioxide, and nitrogen oxides. This causes the rainwater to be more acidic than usual, and this can react with minerals. What is this process called?
This process is when erosion puts pressure on rocks causing the rock to peel off in layers. For example, the rock layers peeling off the rock are like how onion layers peel off the onion. This mostly happens with granite. Another name for this is called pressure release. What is the name of this process?
Exfoliation!!!
What is the definition of a biological weathering in a physical sort of way?
Biological weathering happens when living organisms break down rock without changing the rocks chemical makeup.
What two types of rock react with acid rain the best?
Limestone and Marble!!!
Salt crystal growth happens when...
This process happens when salt water seeps into the pores of rocks and evaporates leaving salt crystals behind. Over time the salt crystal will eventually push apart the rock, as a result the rock will eventually be broken down into small pieces.
What is the definition of biological weathering involving chemical weathering?
Biological weathering happens when living organisms produce chemicals that can break down rocks, and this kind of biological weathering can change the rocks chemical makeup.
Hydrolosis is when what and minerals help create new minerals in rocks?
Water!
