Question 9

comes from glacier and mountains (like run off)

Answer 9

ground water flow

Question 10

these are part of water cycle because of sweat/pee

Answer 10

organisms

Question 11

why do we have world wide water shortages if we have so much water

Answer 11

Most of the water is salt water and you can’t drink it. In some places it doesn’t rain and it can’t be collected.
97% earth is saltwater, 3% fresh water (rivers and streams make up 0.03% is on earth’s surface)

Answer 27

gets colder

Question 28

what is an isobar

Answer 28

lines on a map that indicate areas with the same barometric pressure

Question 29

weather with low barometric pressure

Answer 29

rainy, windy, bad

Question 30

weather with high barometric pressure

Answer 30

dry, clear

Question 31

A high pressure system sinks or rises

Answer 31

sinks bc more dense

Question 32

a low pressure system sinks or rises

Answer 32

rises bc less dense

Question 33

how do low and high pressures spin and in what directions?

Answer 33

low-inward, counterclockwise high-outward, clockwise

Question 34

Does air move from high to low or low to high pressure?

Answer 34

high to low

Question 35

what causes wind?

Answer 35

the flow of gases or air from an area of high pressure to low pressure resulting from uneven heating of the ground.

Question 36

Explain convection as it relates to movement of air

Answer 36

High pressure heats the ground and then air rises and cools.Reaches a point where is loses energy and sinks again.

Question 37

Understanding a station model

Answer 37

The tail spins away from the feathers indicating clockwise or counterclockwise. The tail also points to the direction the wind is coming from. Cloud cover is shown by filling in the circle. Feathers show how many knots of wind. Full feather is 10 knots and half a feather is 5 knots.

Fronts are LPS bc they bring rainy, cloudy weather

Question 41

what is dew point

Answer 41

the point at which air is saturated with water vapor

Question 42

How do cold fronts differ from warm fronts?

Answer 42

cold-cold air mass takes the place of a warm one, rapid weather changes, widespread cloud coverage, fog warm-a warm air mass takes the place of a cold one, slow weather changes, intense sun coverage, thunderstorms during summer
