Question | Answer |
Most of the atmoshpere is made up of ______________ and __________________. | Nitrogen and Oxygen |
List the layers of the atmosphere starting with the closest to Earth: | Troposphere, Stratusphere, Mesosphere, Thermosphere |
What is the thinnest layer of the atmosphere? | Troposphere |
What are 4 properties of weather: | air tempature, humidity, air pressure, precipitation |
If the air around us feels damp and sticky, we call the weather ___________________. | Humid |
__________ have really low humidity ____________________ have really high humidity | deserts, rainforests |
______________ air has higher pressure than _____________ air. | cool air, warm air |
Sleet and hail are types of ________________. | precipitation |
Explain the 6 steps in evaporation and condensation | 1.Sun heats water 2. water particles take in energy 3. particals move faster and farther 4. Particals become h20 vapor and as they cool they move up higher 5. lose energy as they move up 6. water vapor turns into liquid |
What happens to a puddle of water on a sunny day? | It evaporates because of the heat energy |
How does water enter and leave the atmoshpere? | It enters as water vapor and leaves as precipitation |
How does the Sun's energy affect Earth's weather? | Sun powers evaporation and without it water would collect |
What is considered a blanket in the air? | Stratus clouds/ atmoshpere |
Liquid to solid= | freezing |
solid to liquid= | melt |
liquid to gas= | evaporation |
Water that falls from the clouds to the ground= | precipitation |
What type of cloud has flat bottoms and grow dark before a storm? | cumulus |
What type of cloud form in layers and are the lowest clouds in the sky? | Stratus |
What type of clouds are thin, whispy and made of tiny bits of ice | Cirrus |
At what temperature does water freeze? | 32 degrees Farenheit |
One of the wettest places on Earth is ____________ and one of the driest is __________. | Hawaii, South America |
What happens at the boundary between 2 air masses? | a change in weather |
What are 2 facts about tornados? | 1. rotating funnel of wind
2. Speeds up to 250 miles per hour |
What are 2 facts about hurricanes? | 1. Develop over water
2. can cause severe damage |
What is the difference beteween weather and climate? | Climate is a weather pattern year after year;
Weather is the condition of the atmosphere at a certain time and place |
What do latitude, global winds, and ocean currents all have in common? | They all determine climate |
Earth's water has been ________________________. | recycled for billions of years |
The _______________________ the altitude of a mountain, the _______________ the air temperature. | Higher, lower |
If the climate on one side of a mountain is dry, what will be the climate on the other side? Why? | Wet because as the cloud moves up the mountain, the H20 vapor condenses and falls as precipitation. By the time it passes over, it will be dried out. |
The characteristic of weather of a region over the course of several years | Climate |
A measure of how far a place is from the equator | latitude |
The directed flow of a gas or liquid | current |
A measure of how high a place is above sea level | altitude |
The directed flow of water over long distances through the ocean | Ocean current |
Winds that circulate the air between the equator and the poles | global winds |
Where the latitude is zero degrees | equator |
Hurricanes usually happen in the __________________ and northeast ______________ oceans | Atlantic, Pacific |
____________________ are storms that bring violent winds, large waves, floods, and lots of damage. | Hurricanes |
Why would a weather prediction be considered an opinion rather than a fact? | A prediction is a guess and an opninion is what you think |
Draw a warm front/Cold front/stationary front. | |
A large region of the atmosphere where the air has similar propterties throughout | Air mass |
A tool that is used to measure air pressure | Barometer |
The average weather pattern of a region over time | Climate |
A collection of tiny water droplets or ice crystals that hang in the air | clouds |
Forms when cold air masses push under a warm air mass | Cold Front |
A boundary between air masses that are not moving | Stationary front |
When a warm air mass pushes into a cold air mass, this forms | Warm front |
A tube that collects water. It shows the amount of rainfall | Rain Gauge |
Measures air temperature in degrees (Celsius/Farenheit) | Thermometer |
The movement of water between Earth's surface and the air | Water cycle |
When a liquid changes slowly to a gas | Evaporation |
To predict weather conditions | Forecast |
Points in the direction from which the wind is blowing | Wind Vane |
Water in the gas state | Water Vapor |
A boundary between air masses with different temperatures | Front |
The force of air pushing on an object | Air pressure |
