What are the six steps of the rock cycle?

The Six Rock Cycle Steps

  • Weathering & Erosion. Igneous, sedimentary, and metamorphic rocks on the surface of the earth are constantly being broken down by wind and water.
  • Transportation.
  • Deposition.
  • Compaction & Cementation.
  • Metamorphism.
  • Rock Melting.

How are erosion and weathering related to sedimentary rocks?

Organic weathering happens when plants break up rocks with their growing roots or plant acids help dissolve rock. Once the rock has been weakened and broken up by weathering it is ready for erosion. Erosion happens when rocks and sediments are picked up and moved to another place by ice, water, wind or gravity.

Which is the natural process of breaking down rocks?

Breaking down rocks o build houses. Releasing acid in order to extract nutrients from rocks for survival. Erosion too is the natural process of breaking down rocks into sand-like particles. The only difference between weathering to erosion is the presence of agents like water and wind.

What happens to rocks during the process of erosion?

Physical erosion describes the process of rocks changing their physical properties without changing their basic chemical composition. Physical erosion often causes rocks to get smaller or smoother.

What makes soft rock erode faster than hard rock?

Soft rock like chalk will erode more quickly than hard rocks like granite. Vegetation can slow the impact of erosion. Plant roots adhere to soil and rock particles, preventing their transport during rainfall or wind events.

What causes rocks to break open in a river?

Wind carrying sand wears particles off rock like sandpaper. Rushing river water and crashing surf rub off all the rough edges of rocks, leaving smooth river rocks or pebbles behind. Water seeps into the cracks in mountain rocks, then freezes, causing the rocks to break open.
