Surface tension is the property of water in which...
water molecules at the surface tend to stick together.
water spills easily.
water tends to be see-through.
Refer to the picture of water sticking to a leaf; this is occurring because of:
Adhesion
Cohesion
Describe COHESION.
Water molecules attracted to other substances.
Water molecules climbing upwards against the force of gravity.
Water molecules dissolving many substances because of its polarity.
Water molecules attracted to other water molecules.
Water's ability to stick to glass is
adhesion
cohesion
surface tention
capillary action
Which part of a water molecule has a Negative Charge?
The Hydrogen

no adhesion, cohesion, high specific heat, universal solute
You body sweats to help prevent you from overheating. How does water regulate 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
What is the term for water's ability to defy gravity and climb up a tube?
Capillary Action
Specific Heat
Universal Solvent
Magic
What is the term for water's ability to defy gravity and climb up a tube?
Capillary Action

Why does ice float?
water expands when it freezes, making ice less dense than water
water compacts when it freezes, making ice more dense than water
hydrogen bonds in water push the ice to the surface
ice is afraid of water, and avoids it
A water strider can skate along the top of a pond because:
covalent bonds result in water cohesion (surface tension)
hydrogen bonds result in water cohesion (surface tension)
water striders have adapted to take advantage of water cohesion
water striders are afraid of water and avoid it

Both terrestrial and aquatic cycles operate together
What organisms form fossils?
animals
plants and animals
CaCO2
sedimentary rocks
How do fossils form?
ancient biomass is converted to fossil fuels through cellular respiration
ancient biomass is converted to fossil fuels through time, heat and pressure
current biomass is under heat and pressure until they become fossils
atmospheric carbon diffuses into the soil and forms fossil fuels
Humans burn fossil fuels and wood, releasing carbon dioxide into the atmosphere. This carbon dioxide is then absorbed by trees for photosynthesis. These processes are contributory to which chemical cycle?
The carbon cycle
The water cycle
The nitrogen cycle
