Vocabulary for S6E5f
1. On the next blank page of your spiral notebook, you need to write the Unit E.Q., Lesson E.Q.,
and Learning Objective below:
 Unit E.Q.: How is the Earth constantly changing?
 Lesson E.Q.: How do changes on the Earth’s surfaces occur over time?
 Learning Objectives: I can explain the effects of physical processes (plate tectonics,
erosion, deposition, volcanic eruption, gravity) on geological features including oceans
(composition, currents, and tides) (S6E5f).
2. After you have written the items above, you need to write the words and definitions below.
 Vocabulary:
Deposition-dropping of sediments that occurs when gravity, a glacier, wind, or water loses its energy
and can no longer carry its load
Erosion-the process by which the surface of the earth is worn away and transported by the action of
water, glaciers, winds, and gravity
Weathering-the various mechanical and chemical processes that cause exposed rock to break into
smaller pieces
Mechanical Weathering-any of the various weathering processes, such as ice wedging, animals
burrowing, and plant roots, that cause physical breakdowns of exposed rock without any change in
the chemical composition of the rock
Chemical Weathering-any of the various weathering processes that cause exposed rock to undergo
chemical breakdown, changing the minerals or completely dissolving them
Ice Wedging-mechanical weathering process that occurs when water freezes in the cracks of rocks
and expands, causing the rock to break apart
Oxidation-chemical weathering process that occurs when minerals are exposed to oxygen and water
over time
Burrowing-the act of making a hole or tunnel in the ground by a rabbit, fox, or similar animal that
causes rocks to break apart
Slump-type of mass movement that occurs when a mass of material moves down a curved slope
Creep-type of mass movement in which sediments move down-slope very slowly and causes trees
and fences to lean downhill and curve
Landslide-the downward falling or sliding of a mass of soil or sediment on or from a steep slope
Rockslide-a landslide of rocks
Mass Movement-any type of erosion that occurs as gravity moves materials down-slope
Abrasion-a type of erosion that occurs when wind-blown sediments strike rocks, polishing it through
scratching and scraping
Deflation-the removal of loose rock material, sand, and dust by the wind
Glacier-large, moving mass of ice and snow that change large areas of Earth’s surface through erosion
and deposition
Dune-a sand hill, mound, or ridge formed by the wind, piling up sediment behind an obstacle; usually
in desert regions or near lakes and oceans
Loess-windblown deposit of tightly packed, fine-grained sediment that is usually yellowish and found
in the Mississippi Valley and Europe and Asia
