Exogenic Processes and Weathering Quiz

Exogenic processes interconnected with the atmosphere, hydrosphere, and biosphere include weathering, erosion, transportation, and deposition. Weathering on site is the breakdown of rock sediments. Mechanical weathering is the physical breakdown of a rock/grain or chunks. Exfoliation occurs when rocks split into onion-like sheets. Chemical weathering occurs when there is a chemical change. Erosion is the separation and removal of weathered and unweathered rocks. Sand dunes in Pacay, Ilocos Norte, are formed by ______.

Erosion by glaciers is the permanent body of ice/recrystallized snow that shows evidence of movement. Water is the most common erosion agent. Mass wasting or mass movement is the downslope movement of soil and rocks due to gravity. Debris is predominantly coarse ______.

Deposition occurs when sediments settle out of the transporting medium. When a glacier melts, the rocks are deposited to the ground/velocity of wind and water decreases, and grains and particles are deposited. In rivers (fluvial) environments, flat areas and slow-moving commonly ______.

Volcanism and Plate tectonics are geological processes. Earth's internal heat is essential in sustaining life on Earth. Magma is melted rocks found beneath the earth. Lava is when magma emerges to the surface. The melting point of rocks is ______.

Crystallization occurs when magma cools and minerals start to ______.
