Rocks
This type of rock forms when magma or lava cools and solidifies.
Igneous Rock
Karst landscapes usually form in this type of rock.
What is limestone?
The breakdown of rock in its original place.
What is weathering?
The wearing away and removal of rock and soil.
Erosion
The downhill movement of material due to gravity.
What is mass movement?
Granite and basalt are examples of this rock type.
What is igneous rock?
The chemical process where limestone is dissolved by weak carbonic acid.
What is carbonation?
This type of weathering involves freeze–thaw action.
What is mechanical (physical) weathering?
The movement of eroded material by wind, water, or ice.
What is transportation?
A rapid movement of rock and soil down a slope, often after heavy rain.
What is a landslide?
This rock type is formed from layers of sediment being compacted and cemented.
What is sedimentary rock?
A pavement with blocks separated by deep cracks.
What is a limestone pavement?
The weathering process where minerals in rock react with oxygen or water.
What is chemical weathering?
This erosion process involves rocks colliding and breaking into smaller pieces.
What is attrition?
A slow movement of soil down a slope.
What is soil creep?
Marble and slate are examples of this rock type, formed by heat and pressure.
What is metamorphic rock?
An underground feature formed by dripping water depositing calcium carbonate.
What is a stalactite or stalagmite?
The breaking down of rock by plants and animals.
What is biological weathering?
This erosion process involves rocks scraping against surfaces.
What is abrasion?
The movement of water-saturated soil down a slope.
What is mudflow?
The process by which sedimentary rock layers are pressed together to form solid rock.
What is compaction and cementation?
A circular depression on the surface where a river disappears.
What is a sinkhole?
The expansion and compression of rocks in a desert due to heat.
What is onion weathering.
This process describes rocks dissolving in acidic water.
What is solution?
A sudden fall of rock from a steep cliff.
What is a rockfall?
