What is the primary source of energy that drives weathering?
Sun
What is the process that breaks down rock into sediments on-site called?
Weathering
What is the term for the process where natural cracks are formed in a rock, breaking it into rectangular blocks or irregular chunks?
Exfoliation
Which process involves water inside the rock experiencing regular freezing and thawing?

What is the process where plants growing on the rock's surface pry it open called?
Root wedging
When salt crystallizes and weakens the rock, causing it to disintegrate when exposed to wind or rain, what type of weathering is this?
Salt wedging
What is the process of separation and removal of weathered and unweathered rocks and soil from its substrate?
Transport
Which process involves reaction of oxygen with minerals in the rock, forming oxides?
Oxidation
What causes the surface to break-off into sheets when it cools?
Dissolution
What involves the downslope movement of rock, soil, and ice due to gravity?
Mass Wasting
Which type of erosion commonly occurs in flat, bare areas or dry, sandy and loose soils?
Wind Erosion
What is the forward rotation out of the slope of a soil or rock mass called?
Topple
What involves processes by which sediments are moved along from the source to where they are deposited?
Transport
What causes water to be absorbed into the crystal structure of the mineral, causing it to expand?
Hydration
When fungi and lichens secrete organic acids, what type of weathering is occurring?
Biological Weathering
What occurs when materials are saturated and move downslope as a viscous fluid?
Flow
What type of weathering occurs when a rock is exposed to high temperature, causing its outer layer to expand?
Thermal expansion
Which type of weathering involves the reaction of oxygen with minerals in the rock, forming oxides?
Chemical weathering
What process occurs when salt crystallizes, pushing apart the surrounding grains and weakening the rock, causing it to disintegrate when exposed to wind or rain?

A topple
Which type of erosion involves rivers starting as small individual streams called tributaries?
Erosion by water
What involves processes by which sediments are moved along from the source to where they are deposited?
Transport
This quiz covers exogenic processes such as weathering and erosion, which are important geological phenomena that shape the Earth's surface. The quiz explores the breakdown of rocks, transformation into sediments, and the influence of the Sun's energy on weather patterns.
