Sample Response: When there is less rainfall, land,
which is part of the geosphere, becomes dry. When there
is not enough water, plants will not get the nutrients they
need from the soil and animals will not get enough water,
and they will die. Both plants and animals are part of the
biosphere. Less precipitation would also mean less water
in lakes and groundwater, parts of the hydrosphere, and
less evaporation. The atmosphere may also be affected
due to less water vapor.
Which ideas did you include in your answer? Check all
that apply.
Droughts can cause the geosphere to be very dry.
Droughts can affect the survival of organisms in the
biosphe.
Droughts can affect the amount of water in the

"A person needs unconditional love and acceptance in order to reach her true potential." "A person's behavior reflects unconscious conflicts and emotions that result from early childhood experiences." "Emotional responses reflect biological processes such as hormones and brain chemistry."

Answers

Answer:
