What sphere is a mixture of Nitrogen, Oxygen, and other gases that extends more than 700 km above the Earth's surface?
Atmosphere
What are the different temperature scales?
Celsius, Fahrenheit, and Kelvin
What is humidity?
The general term for the amount of water vapor present in the air
What is wind speed?
Wind speed is the rate at which air moves from one place to another
What are tornadoes?
Spinning air columns from thunderstorms
Which Earth sphere includes all living things?
Biosphere
How is temperature different from heat?
Temperature measures how hot or cold something is, while heat is the transfer of thermal energy
What instrument is used to measure humidity?
A hygrometer
What instrument is used to measure wind speed?
Kilometers per hour (km/h), meters per second (m/s), or knots
How do tornadoes form?
Warm, moist air rising
Which sphere of the Earth includes all the water on the planet, including oceans, lakes, and rivers?
Hydrosphere
What happens to the particles of a substance when temperature increases?
The particles move faster and spreed father apart
How does warm air hold more water vapor then cold air?
What is wind direction?
Wind direction in the direction from which the wind is blowing
What is a waterspout?
A tornado that forms over water
How does the biosphere depend on the atmosphere?
The biosphere depends on the atmosphere for air to breath
Why does metal feel colder then wood at the same temperature?
Metal transfers heat away from your hand faster then wood
Why do we feel more uncomfortable on a hot day with high humidity then on a hot day with low humidity?

Which sphere includes all the solid, non-living parts of the planet, such as rocks, minerals, and mountains?
Lithosphere
How does temperature influence the rate of chemical reactions?
Higher temperature usually increases reaction rate because particles collide more often
If warm air and cold air contain the same amount of water vapor, which one will have a higher relative humanity?
Cold air
How does wind speed usually change with altitude?
Wind speed generally increases with altitude because there is less friction
