When a fault forms, or when there is abrupt movement on an existing fault, energy that has accumulated over time is released in the form of vibrations, that move in all directions through the surrounding rock, this is an event called

Earthquake

The time it takes to use up a certain proportion of the reserves of a mineral at a given rate of use.

Depletion time

Any change in water quality that can harm living organisms or make the water unfit for human uses such as drinking, irrigation, and recreation.

Water Pollution

The natural nutrient enrichment of a shallow lake, a coastal area at the mouth of a river, or a slow-moving stream. It is caused by runoff of plant nutrients such as nitrates and phosphates from land bordering such bodies of water.

Eutrophication

Are broad and diffuse areas where rainfall or snowmelt washes pollutants off the land into bodies of water.

Nonpoint sources

The combination of the crust and the rigid, outermost part of the mantle is called ____. A zone that we find the mineral resources on which we depend.

Lithosphere

The scientific study of dynamic processes taking place on the earth’s surface and in its interior.

Geology

Rocks that have changed over time from extreme heat or pressure.

Metamorphic

A naturally occurring element or inorganic compound that exists as a solid with a crystalline internal arrangement of its atoms or ions.

Minerals

A series of extremely long waves caused by a large and sudden displacement of the ocean, usually the result of an earthquake below or near the ocean floor.

Tsunami

Is used mostly to mine coal and various mineral resources on hilly or mountainous terrain.

Contour Strip

Involves spreading out solid waste in thin layers, compacting it, and covering it with a fresh layer of clay or plastic foam.

Sanitary landfills

Involves the extraction of mineral deposits that lie in large horizontal beds close to the earth’s surface.

Strip

The process by which fertile land becomes desert, typically as a result of drought, deforestation, or inappropriate agriculture.

Desertification

Comes from dead plant and animal remains and tiny particles of weathered and eroded rocks.

Sedimentary

With this method, after a mountaintop is blown apart, enormous machines plow waste rock and dirt into valleys below the mountaintops. This destroys forests, buries mountain streams, and increases the risk of flooding.

Mountain removal

The interaction of physical and chemical processes that change the earth’s rocks from one type to another is called.

Rock Cycle

The following groups are ways to reduce water pollution, except

Allow yard wastes to enter storm drains

Process of removing dissolved salts from ocean water or from brackish water in aquifers or lakes.

Desalination

A biological process in which aerobic bacteria remove as much as 90% of dissolved and biodegradable, oxygen demanding organic wastes.

Secondary sewage treatment

The process of using water to break down hazardous compounds into simpler and less harmful substances

Hydrolysis

A porous, water-saturated layers of sand, gravel or bedrock through which groundwater flows.

Aquifer

Discharge pollutants at specific locations through drain pipes, ditches or sewer lines into bodies of water.

Point sources

The earth’s innermost zone. It is extremely hot and has a solid inner part, surrounded by a thick layer of molten rock, or hot liquid rock, and semisolid material.

Core

Common ground water pollutants includes

all of the above

A solid combination of one or more minerals found in the earth’s crust.

Rock

In rural and suburban areas with suitable soil, water from each house usually is discharged into a septic tank with a large drainage field. These are called

Sewage

Some precipitation infiltrates the ground and percolates downward through spaces in soil, gravel, and rock until an impenetrable layer of rock or clay stops it. The freshwater in these spaces underground is called

Ground water

The following statements are TRUE, except

Access to freshwater is not a global health issue.

A rock that contains a large enough concentration of a particular mineral.
