Forces
This force pulls rocks, water, ice, and soil downhill.
What is gravity?
The process that breaks rock into smaller pieces without moving it.
What is weathering?
The movement of weathered material from one place to another.
What is erosion?
This Earth system includes rivers, glaciers and oceans.
What is the hydrosphere?
Humans speed up erosion through farming, mining and construction.
What is human-caused erosion?
These forces originate inside Earth and build mountains and plateaus.
What are internal forces?
Weathering that changes the chemical makeup of rock minerals.
What is chemical weathering?
This agent of erosion is the main cause of continental erosion.
What are streams?
This system consists of rocks, soil, and landforms.
What is the geosphere?
This agricultural practice affects soil through the growth of many crops.
What is surplus farming?
This type of force reshapes Earth's Surface through water, wind, and ice.
What are external forces?
This type of weathering breaks rock physically without changing composition.
What is mechanical weathering?
This terms describes the amount of water flowing through a stream.
What is discharge?
This system includes plants, animals, and microorganisms.
What is the biosphere.
This human activity removes vegetation and increases slope instability.
What is deforestation?
This concept explains how Earth's crust rises when mass is removed by erosion.
What is isostatic rebound?
This chemical weathering process occurs when minerals react with oxygen.
What is oxidation?
This feature forms when rivers deposit sediment during flooding.
What is floodplain?
This system controls weather and climate patterns.
What is the atmosphere?
This environmental issue increases chemical weathering of rocks.
What is acid rain?
These two types of geologic processes describe slow changes versus sudden events.
What are gradual and catastrophic processes?
This factor increases the rate of both chemical and mechanical weathering.
What is the presence of water?
This process explains how sand ripples migrate along deserts.
What is saltation?
This idea explains how changes in one Earth system affect others.
What is system interaction?
This terms describes humans acting as a major force shaping Earth's surface.
What is human as a geologic force?
