What is the uppermost layer of soil, # 1 on the diagram, consisting of an organic layer made up of partially decayed plant and animal debris?
A
B
O
R
Why does ice float?
water expands when it freezes, making ice less dense than water
hydrogen bonds in water push the ice to the surface
As water freezes, air gets trapped making it more dense
As water freezes, it takes up more oxygen from the atmosphere, causing it to be more dense
Why does water move from the roots to the leaves of plants?
Water is pushed by solutes
Capillary action pulls the water molecules up like a chain
Water is pulled by gravity
Water cannot move up roots to leaves
A paperclip floating on water is an example of what property of water?
capillary action
surface tension
universal solvent
specific heat index
Which of the following is an example of cohesion?
water sticking to water
water sticking to glass
oil sticking to plastic
hydrogen sticking to oxygen
Water is polar. What does that mean?
it is a molecule with opposite charges on opposite ends
it is a molecule with no charge
it is a molecule with identical charges on opposite ends
it is a molecule with too many protons
Water striders can walk across the surface of calm water. Their feet push the surface of the water down slightly, but they do not break the surface. Why?
The insects are small enough to see the individual water molecules, so they are able to step carefully from one molecule to the next
The insect’s feet are non-polar, so they are repelled by the polar water molecules and are pushed away from the water’s surface.
The insects are light enough so they do not break the hydrogen bonds holding the water molecules together
The insects actually use their wings to hover slightly above the water’s surface and they only skim it with their feet.
New soil deposition seals off the ends of a river and the cut-off becomes a(n) ________________ that will eventually dry up.
Oxbow Lake
Kidney scar
Flood Plain
Meander
What is a thermocline?
A rapid change in temperature with depth
A rapid change in temperature with latitude
A rapid change in salinity with depth
A rapid change in density with depth
The lines that determine distance from the equator are called?
altitude
latitude
meters
longitude
Which is NOT a unique property of water?
Frozen water floats on liquid water.
Water covers most of the Earth’s surface and retains a large amount of heat.
Water molecules stick to each other through hydrogen bonds.
Water cools very rapidly.
Your body sweats to help prevent you from overheating. How does water regulate body temperature?
it lets heat pass through it
it absorbs a lot of heat, then decreases in temperature
it absorbs a lot of heat, but only increases a little in temperature
heat is afraid of water and avoids it
