I'm struggling with this subject for my lc , I need it to get into trinity college. I'm worried.

# data[].attributes.body
from the powerpoint I am unsure on what erosion is as i dont get geography grinds

There are 5 processes. Hydraulic Action, Abrasion, Attrition, Compression and Solution.
Hydraulic Action is most effective during storms, exerting pressure up to 25 tonnes er square metre on the coastline.
Compressed Air has an explosive effect.

There are 5 processes of erosion:

Hydraulic Action, Abrasion/ Corrasion, Attrition, Compression/ Cavitation, Solution
2. compressed air is new to me
Hydraulic action refers to explosive power

PROCESSES
1. hydraulic action
2. abrasion
3. attrition
4. compression
5. solution

1. 5 processes of erosion. Hydraulic action, Abrasion, Attrition, Compression, Solution. 2. Key with Attrition - hurls against each other! 3. Compressed air is something new to me
Know more about. Compression and Solution. Ask about - how the 5 processes work together

1.Hydraulic action is most effective during storms, exerting pressure up to 25 tonnes per square metre on the coastline.

2.attrition is also referred to as the sandpapering effect.

3. coastal retreat, also known as headward erosion, is dominant at coastlines rather than vertical erosion

what would happen if rocks didn't have more

and are there any more process we don't know about

compressed air is new to me.

hydraulic action fractures rocks, There are 5 processes of erosion, Solution refers to the dissolving of rock by sea water, How rough can waves get on the coast, What is the hardest wave ever hitting Ireland.

3.
rock can be dissolved by water.
waves can hit the coastline at 25tonnes/ sqm.
compressed air has an explosive effect on the coastline.
