Chapter 7

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
