ENV320 FINAL ACTUAL EXAM PAPER
2026 QUESTIONS WITH ANSWERS
GRADED A+
◍ select the sentences that summarize land use in the united states..
Answer: XXX there are several ways that the us manages its 2.3 billion
acres of land.correct: grasslands, like pastures and rangeland, make up
approximately 29.0%, forests 27.9%, cropland 17.3%, miscellaneous uses
8.7%, urban 3.1% and special uses 14.0%.
◍ What is the hydrological cycle?.
Answer: The endless movement of water around the globe in three states:
solid, liquid, and gas.
◍ What are the six primary reservoirs for water?.
Answer: Oceans, ice caps and glaciers, subsurface water, surface water, the
atmosphere, biological water.
◍ What percentage of fresh water makes up the total amount of water on
Earth?.
Answer: 2.5%
◍ select the sentences that summarize land management in the united states..
Answer: correct: for instance, year-round grazing on grasslands can lead to
overgrazing and the growth of unwanted plants.correct: in another example,
a popular mining method in the us is open-pit mining.incorrect: different
methods of management of these land types have different effects on the
environment.incorrect: rotating grazing animals can reduce these
effects.incorrect: while it is an effective way of gaining mineral resources, it
has some negative effects like the removal of vegetation, which leads to soil
erosion and increased runoff.
,◍ which are environmental effects of acid rain? select all that apply..
Answer: increases water aciditydecreases trees' ability to grow
◍ Where can biological water be found?.
Answer: In plants and animals.
◍ how has the burning of fossil fuels impacted the carbon cycle? select all that
apply..
Answer: 0.67 of 1increased amounts of co2 in the atmosphereincreased
amounts of carbonic acid in the ocean
◍ describe the effects of the use of chemical fertilizers in farming. select all
that apply..
Answer: 0.25 of 1incorrect: it increases soil phcorrect: it improves
short-term soil fertility.
◍ complete the response to the following statements about urbanization and its
impacts on natural populations..
Answer: increased, reduced, increased, increased
◍ why does an increase in carbon dioxide in the atmosphere result in more
violent hurricanes?.
Answer: carbon dioxide in the atmosphere absorbs light energy and reflects
it back to earth. this energy is transformed into thermal energy in the earth's
oceans. hurricanes get kinetic energy for their motion from the thermal
energy of the water. warmer oceans cause more violent hurricanes.
◍ What type of water makes up the remaining percentage of the total amount
of water found on Earth?.
Answer: Oceans and saline water.
◍ how do external events impact global temperatures?.
Answer: changes in the earth's axis cause a redistribution of solar energy,
which impact global temperatures.
◍ what explains a way in which humans impact global temperatures? select all
that apply..
, Answer: cement production because it releases co2burning of fossil fuels
because it releases co2urbanization because it decreases reflective surfaces
◍ Why is it important to know the distribution of water on Earth?.
Answer: To properly manage and conserve water resources as the
population grows.
◍ What is interception in the context of the hydrological cycle?.
Answer: The movement of rain or melting snow into the soil at Earth's
surface.
◍ What occurs when precipitation does not seep into the soil?.
Answer: Surface runoff collects into surface water bodies or evaporates into
the atmosphere.
◍ if co2 concentrations in the air continue to increase, what effects might we
see in the oceans? select all that apply..
Answer: ocean water will become more acidic.increased solubility of
carbonates will occur.populations of photosynthetic algae will increase.
◍ What is the process called when precipitation infiltrates the soil?.
Answer: Infiltration.
◍ What is deep percolation?.
Answer: The vertical downward movement of infiltrated water through the
soil.
◍ What happens when groundwater returns to the surface?.
Answer: It can become baseflow of streams, freshwater springs, or
submarine discharge.
◍ which are renewable resources? select all that apply..
Answer: forestsfreshwatersolar energy
◍ What drives the hydrological cycle?.
Answer: Energy from the sun.
◍ What is thermal convection?.
Answer: The transfer of thermal energy through the movement of a liquid or
, gas.
◍ which correctly describes a nonrenewable resource and how to reduce its
use so that reserves of the resource can be sustained?.
Answer: XXX coal; increase the use of electric cars
◍ what is true about oil and solar energy?.
Answer: both are continually produced by natural processes but differ
greatly in the rate at which they are renewed.
◍ What is Hadley circulation?.
Answer: The process where warm, moist air at the equator rises, cools, and
produces rainfall.
◍ At what degree of latitude does cool, dry air sink to the surface?.
Answer: 30 degrees N and S latitude.
◍ which describes what is happening when you turn on your tv?.
Answer: energy found in coal, nuclear fuel, sunlight, water, or other sources
is transformed into electrical energy. the tv then transforms electrical energy
into light and sound energy.
◍ what should be considered in a cost-benefit analysis of a new coal mine?.
Answer: 0.17 of 1 (i think it should include the other answers and not the
incorrect one that i showed)incorrect: what actions are moral or faircorrect:
how the community benefits from jobs at the mine
◍ what are long-term impacts of hurricanes on the environment? select all that
apply..
Answer: 0.67 of 1massive fish die offs could occur.earth's coastal
landscapes could be reshaped.
◍ which actions would reduce someone's carbon footprint? select all that
apply..
Answer: 0.67 of 1carpoolingswitching to solar energy
◍ What is the Intertropical Convergence Zone (ITCZ)?.
Answer: A band near the equator where trade winds meet, causing warm,
