GES 120 Exam 1 Review Questions
and Answers7
What makes something high quality or low quality - ANSWERS -is determined by how useful the
energy or matter is to do work or for human
Nonrenewable Energy - ANSWERS -Some sources include fossil fuels such as oil, coal, and
natural gas and minerals such as copper and silver are found within the Earth's crust. Minerals
and coal are extracted from mining and oil is extracted through drilling and pumping.
Rock cycle - ANSWERS -Rocks are recycled over millions of years by three processes—erosion,
melting, and metamorphism—that produce sedimentary, igneous, and metamorphic rocks,
respectively. In these processes, rocks are broken down, buried, and sometimes melted and
fused together into new forms by heat and pressure. They are also cooled and sometimes
recrystallized within the earth's interior and crust. Some rock is then uplifted and exposed at the
surface where erosion again breaks it down.
Ozone - ANSWERS -contains enough ozone (O3) gas to filter out about 95% of the sun's harmful
ultraviolet (UV) radiation. It acts as a global sunscreen that allows life to exist on the earth's
surface. Chlorofluorocarbons (CFCs) and other halogenated ozone depleting substances (ODS)
are mainly responsible for man-made chemical ozone depletion. Life need the ozone layer
because without it the Sun's harmful UV Rays would make the Earth too hot. Buy air-
conditioning and refrigeration equipment that do not use HCFCs as refrigerant. Buy aerosol
products that do not use HCFCs or CFCs as propellants.
What are natural resources? - ANSWERS -Are materials and energy provided by nature that are
essential or useful to humans.
What are the categories of natural resources? List examples of each. - ANSWERS -Inexhaustible
resources: This material is expected to last forever on a human timescale = solar energy.
, Renewable resources: is a resource that can be used repeatedly because it is replenished
through natural processes as long as it is not used up faster than nature can renew it = forests
and clean air.
Nonrenewable (exhaustible) resources: are those that exist in a fixed amount, or stock, in the
earth's crust. They take millions to billions of years to form through geological processes. On the
much shorter human timescale, we can use these resources faster than nature can replace
them = oil and coal.
Ecosystem services - ANSWERS -are the natural services provided by healthy ecosystems that
support life and human economies at no monetary cost. For example, forests help purify air and
water, reduce soil erosion, regulate climate, and recycle nutrients.
Natural Capital - ANSWERS -consists of natural resources (blue) and ecosystem services (orange)
that support and sustain the earth's life and human economies
The Scientific Method - ANSWERS -is a process that helps scientists to test out hypotheses and
learning more about specific fields of science in order to help people live healthier and more
sustainable lives
Dependant variable - ANSWERS -is what you measure in the experiment and what is affected
during the experiment
independant variable - ANSWERS -is defined as the variable that is changed or controlled in a
scientific experiment.
Scientific Process - ANSWERS -• Identify the Problem
• Find out what is known about the problem
• Ask a questions to investigate
