Study Notes
Landforms
- Mesas are large, flat-topped landforms with steep sides
- Buttes/kopjees are small, isolated patches of landforms with steep sides
Waterfalls
- Waterfalls are magnificent jumps made by stream or river water at certain specific parts of their course
Caves
- Caves are naturally carved out underground cavities of various dimensions
- Caves have horizontal openings on the surface
- Caves are formed through the process of groundwater percolation, where rocks or other materials lose some of their constituents to the ground water molecules and take in return some component molecules from the ground water
Glacial Transport
- Glacial transport is the result of two types of motions of the ice in a glacial mass
- The first type of motion is a sliding motion of the glacial body along the bed rock, primarily due to gravity
Earthquakes
- There are two broad types of earthquakes: tectonic and non-tectonic
- Tectonic earthquakes are caused by faulting or relative displacements of Earth's crust blocks along rupture planes
- Non-tectonic earthquakes originate from causes different from faulting, such as volcanic eruptions, atomic explosions, landslides, and subsidence

Description
Test your knowledge about the process in which rocks or other materials lose some constituents to groundwater as it percolates through them, while also gaining some component molecules from the groundwater.
