AG Flashcards
Which property of nitrogen atoms makes it possible for nitrogen to occupy spaces in the crystal structure
Nitrogen atoms are similar in shape and size to carbon atoms
Some thunderstorms are caused by convection resulting from the collision of two air masses. Which describes the collision involved in this type of thunderstorm?
A cold front moves into an area with warm air
Which interaction between the atmosphere and hydrosphere causes most ocean currents
Friction from planetary winds on the ocean surface
What occurs when an atom of chlorine and an atom of hydrogen become a molecule of hydrogen chloride
A chemical bond is formed and energy is absorbed
The breaking apart of large molecules into smaller ones is called?
Hydrolysis
Which of these describes a pollution producing process that involves only a physical change?
a. Coal with high sulfur content is burned, producing gases that causes acid rain
b. Chlorofluorocarbons are released, changing ozone in the upper atmosphere into oxygen
c. Hot waste water is discharged into a lake, lowering oxygen levels in the water
C
Which of the following human activities reduces the level of ozone in the atmosphere?
a) using artificial lightning in scientific polar stations
b) using large banks of solar cells for energy production
c) releasing chlorofluorocarbons from aerosol cans
d) destroying large areas of the equatorial rainforest
C
When a person goes to a higher altitude at a rapid rate, the pressure on the eardrum is the result of?
The air pressure inside the ear being greater than the outside pressure
The original shape of a mineral sample was altered when it was hit with a rock hammer. Which physical property caused the mineral to break as it did?
Cleavage
All of these can affect the rate at which solid dissolves in water except
A. Decreasing air pressure
B. stirring the water
C. increasing the temperature of water
D. using larger crystals of the solid
A
If the properties of water were to change so that the solid form was denser than the liquid form, organisms living in a cold pond environment would be less likely to survive because water would no longer_____
Produce a floating insulating layer of ice
A weather balloon is never fully inflated on the ground because of the balloon rises,_________
The air inside expands
Why is a person more buoyant when swimming in saltwater than in freshwater?
Saltwater weighs more than an equal volume of freshwater
Angelo sips water with a straw. What causes the water to rise in the straw?
Sucking the straw lessens the air pressure in it
An athlete sliding too quickly down aerobic experiences a rope burn. Which of the following statement explains why this happens?
a. The motion of the rope produces heat
b. molecules in the rope transfer energy to molecules in the athlete’s hand
c. some of the energy of the slide is converted into heat
d. energy in the rope is converted into heat
C
