Name three ways that weathering breaks a large rock?

Question

how dose wind, water, and frocen water break a large rock?

Answer 1

Water - Through Hydraulic Action. This is when water (generally from powerful waves) rushes into cracks in the rockface rapidly. This traps a layer of air at the bottom of the crack, compressing it and weakening the rock. When the wave retreats, the trapped air is suddenly released with explosive force. The explosive release of highly pressurized air cracks away fragments at the rockface and widens the crack itself.

Frozen Water - By freeze-thaw when water seeps intoa  crack in a rock. It then freezes and expands to around 9-10%. The ice melts and this process repeats until the rock breaks off.

Wind - Blows sand size particles which chip away at the rock over time. Very slowly.

Answer 2

Please learn to spell first.

Answer 3

There are more then 3 ways that weathering breaks rocks.

1. Salt crystallization in cracks and along crystal boundaries

2. Formation of water ice in cracks

3. Formation of clay minerals inside the mineral biotite that causes it to expand, breaking rock. Common in granite

4. Extreme heating and cooling (can cause rocks in deserts to explode! but rare)

5. Natural and human Acid rain

6. Pressure release - the expansion of rocks there were originally deep underground

7. Lightning strikes (surprisingly common on mountains tops)

Answer 4

particles blown in the wind will weather a rock

water will erode it

frozen water in cracks etc can cause it to crack ( water expands when it freezes)
