C. It reduces the amount of UV light that reaches Earth's surface. - AnswersWhat is the role of
the ozone layer?
sunlight strikes the equator relatively directly with little seasonal variation. - AnswersThe
temperatures at the equator remain warm year-round because
West - AnswersThe prevailing winds in the Glacier National Park area of Montana are from the
west. Which side of this mountainous region receives the most rain and snow?
rain shadow - AnswersA(n) ________ is an area that is very dry because the air in that region
has passed over a mountain and lost most of its moisture.
cool, dry air that warms as it moves down over a mountain, picking up moisture. - AnswersA
rain shadow is caused by
absorbs high-energy UV radiation. - AnswersMaintaining the ozone layer is crucial for life
because it
blocks incoming UV radiation, which is damaging to animals and reduces photosynthesis in
plants and algae. - AnswersEarth's ozone layer is extremely important because it
chlorofluorocarbons (CFCs). - AnswersThe destruction of the ozone layer is caused by a chemical
reaction between UV light and
chlorofluorocarbons (CFCs). - AnswersThe ozone hole over Antarctica and the general lowering
of ozone levels elsewhere in the stratosphere have been attributed to the ozone-destroying
properties of
, Earth is tilted on its axis as it orbits the sun annually. - AnswersWhy do higher-latitude
ecosystems experience more pronounced seasons than ecosystems at equatorial latitudes?
heat produced by the sun. AnswersThe major driving force behind winds, ocean currents, and
the global water cycle is-
Water, nutrients, energy, appropriate temperatures - AnswersWhat are the fundamental
resources required to support life?
conserve water in dry environments. - AnswersThe thick, green stems and spike-like leaves of
cacti and euphorbias are adaptations to
Biomes - Answers________ are large areas that have similar environmental conditions and
characteristic plant communities.
B) tropical rain forests. - AnswersThe greatest diversity of plants and animals is found in
A) in the towering treetops. - AnswersIn a tropical rain forest, the majority of animals are found
C) Grassland - AnswersWhich of the following North American biomes has been almost
completely destroyed by agricultural use?
B) The leaves of deciduous trees do not block the light in the spring, therefore allowing sunlight
to reach the forest floor. - AnswersWhy do most of the flowers in a temperate deciduous forest
bloom in the spring?
E) Lack of available water - AnswersIn the fall, the trees in a temperate deciduous forest lose
their leaves primarily as an adaptation to
