Water Cycle
What are plants main role in the water cycle?
They release water vapor into the air.
What factor causes surface currents north and south of the equator to move in different directions?
the Coriolis effect
What would be an example of releasing energy?
a. ice subliming
b. snow melting
c. lake water freezing
c. lake water freezing
Water moves under Earth's surface to fill open spaces, this water is called?
What is the top of this water called?
groundwater
water table
What is urbanization?
the shift from rural to urban
Why is water considered a universal solvent?
Surface currents typically travel ____________ in the northern hemisphere and ____________ in the southern hemisphere?
clockwise-north
counterclockwise- south
What is an example of how the water cycle carries on energy transfer?
A warm ocean current warming the air above it.
Put these river processes in smallest to largest form.
river systems, tributaries, rivers
tributaries, rivers, river systems
Which substance has the strongest acid?
Which substance has the strongest base?
*show document
lemon juice
bleach
Wax was put on the stomata on the leaves of a plant. Five days later, the plant was wilting.
What explains this.
the plant was unable to carry out transpiration
What is the relationship between the white arrows and the black arrows in this map?
*show document
The currents represented by black arrows are caused by the winds represented by white arrows.
When water changes state it either absorbs or releases energy. When does it gain energy?
evaporation
What type of pollution is caused by home cleaners being poured down the drain?
What type of pollution is caused by dumping remains of dead organisms into bodies of water?
chemical
biological
What are ways urbanization can affect water quality?
with more urban areas that means more people live there. more people=more water needed. the people can be sources of pollution
You have a glass of ice, later it turns to water.
Explain.
the ice absorbed energy and turned into liquid water
What is a convection current?
cooler dense water on the bottom, warmer less dense water on the top
*currents that result from density differences
What is an example of how the water cycle carries on energy transfer?
*think about ocean currents
a warm ocean current warming the air above it
Which layer would be recharged quickest?
Which layer provides the best long-term storage of groundwater?
layer one
layer three
What are ways we can stop water pollution?
don't pour chemicals down the drain
take shorter showers/ use less water
don't put trash in water
Explain the water cycle.
the continuous movement of water between the atmosphere, the land, the oceans and living things
What is a deep current?
What is upwelling?
Deep current- movements of ocean water far below the surface
Upwelling-the movement of deep, cold, nutrient-rich water to the surface.
During the day, water from the ocean is transferred to the atmosphere. What describes the energy change that takes place during the transfer?
(think about why it is warm in Florida near the ocean)
energy is transported from the ocean to the atmosphere, which makes the atmosphere warmer.
Draw a water molecule.
Explain how this shows water is a polar molecule.
Draw another water molecule next to the first one to show how two water molecules would arrange themselves.
Polar- one end is negative and the other end is positive
Describe four ways water is important. Then give examples from your life that shows each of the ways that water is important.
1. survival- keeps us hydrated
2. life- most of our body is made of water
3. environment- homes for some animals and mermaids
4. everything is mainly made up of water
