What happens to the rate of weathering if a big rock is broken into smaller pieces?

Mechanical weathering increases the rate of chemical weathering. As rock breaks into smaller pieces, the surface area of the pieces increases figure 5. With more surfaces exposed, there are more surfaces on which chemical weathering can occur. Mechanical weathering may increase the rate of chemical weathering.

Is breaking a rock a physical change?

The breaking of rock through the action of ice is a form of physical weathering. Photo: James Wheeler (www.flickr.com). Weathering is a process by which rocks and minerals are changed. This may be a physical or chemical process of change.

When rocks are physically broken into smaller pieces but the minerals in the rock remain the same?

weathering is when rocks are physically broken into smaller pieces, but the minerals in. the rock remain the same. When a rock is broken down in a way that changes the mineral composition, it is called. weathering.

When plant roots grow into cracks and break up a rock it is?

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.

How ice wedging and plant roots are similar in breaking rocks down?

Mechanical weathering caused by ice wedging and plant roots cause rocks to ‘break’ from the inside out. As the plant root grows and becomes larger, the root will slowly push apart the rock from the inside. Both processes involve breaking the rock apart from the inside of the rock.

What do you call the movement of the surface of the water?

it is called hydrologic cycle, or water cycle, Surface movement includes. rivers, streams, creeks, lakes, ponds, and human-made “flood” control.

What are the 7 steps in the water cycle?

Since that is where about 96% of total water exists on Earth.

  • Step 1: Evaporation. The water cycle begins with evaporation.
  • Step 2: Condensation.
  • Step 3: Sublimation.
  • Step 4: Precipitation.
  • Step 5: Transpiration.
  • Step 6: Runoff.
  • Step 7: Infiltration.
