1

What gas makes up 78% of the air

Nitrogen

2

What is weather

The state of the atmosphere at a given time and place

3

How does a thermometer work

The Liquids and solids will expand when heated

4

What is a meteorologist

People Who study the daily weather and forecast

5

99% of the weight in the atmosphere is found with in how many miles

The first 20 miles or 32 km Off the surface

6

What percent of the suns energy is absorbed by earths surface

51%

7

How much of the suns energy is absorbed by the atmosphere

19%

8

How much of the songs energy is reflected back into space

30%

9

Which way do Isotherms over the land bend during the winter

Tward the poles

10

What’s chart would you use to see if there is a danger of frost bite

A wind chill chart

11

Beufort scale

This is a scale that determines how fast the wind blows from your observations on land or water

12

Why and when do temperature of inversions happen

They happen because of conduction and on clear dry nights when the temperature drops quickly

13

When are temperature inversion destroyed

Late morning

14

When is the sun hottest, when is the earth hottest, why are these different

The sun is hottest around noon however the hottest time of day is around 3 or 4 o’clock. This is because the ground is still not at its hottest

15

Define temprature range

The difference between the highest and lowest temperatures of the day

16

Why does the stratosphere’s temperature rise with altitude

This is because of the presence of ozone

17

Describe the troposphere

This is the lowest layer nearest to the surface this is where gases that are essential to life are this is where weather occurs in temperature increases an increase in altitude This is because the gases absorb very little of the incoming solar radiation instead the ground absorbs this radiation and then heat the tropospheric air by conduction and convection

18

Describe the stratosphere

This layer is found around 31 miles from the surface it is clear dry with study winds very few weather changes this is where jet Aircrafts fly temperature increases with altitude because ozone is heated by radiation from the sun which is warmer than the rest of the air and sits above the denser cooler air

19

Describe the mesosphere

This is a layer that is 51 miles high temperature decreases with an increase of altitude the ionosphere begins here and stretches a poured into the Thermosphere the top portion is known as the meso paws were temperature stays constant

20

Describe thermosphere

Reaches from the meso paws to 310 miles high temperature increases with an increase in altitude this is due to nitrogen and oxygen atoms here absorbing solar energy

21

Describe the ionosphere

Directions from the lower mesosphere to the top of the thermosphere Ions or charged atomic particles are concentrated in this region this is where radio waves are transmitted

22

What are the two greenhouse gases

Carbon dioxide and water vapor

23

What causes excess carbon dioxide to be released into the atmosphere

The burning of fossil fuel’s

24

Describe the green house affect

Greenhouse gases let in the sun‘s UV rays which are longer wavelengths and do not let out this earth infrared energy which is a shorter wavelength Causing the earth to heat up

25

What can we do to stop emitting access carbon dioxide into the atmosphere

Stop burning fossil feels and example of this would be using alternative energy sources

26

What can we do to reduce the current amount of carbon dioxide in the atmosphere

Plant more trees

27

What are the three ways heat is transferred in the atmosphere

Conduction convection and radiation

28

Name the four reasons why water warms more slowly than land

The first reason is because the suns rays penetrate deeper into the water also water spread the heat more easily also some energy is used in evaporation lastly water needs more energy to rise itself 1°

29

What does a falling barometer mean

Rainy weather, more clouds stronger winds Warmer. This is because warm air is more spread out causing it to be less dense which also causes the air pressure to go down. Since it is warmer this means more evaporation which means more clouds and more precipitation

30

What is an anemometer

This is a device that measures wind speed
