Vocabulary
When water turns from a gas to a liquid.
Condensation
The thickest layer of the earth and the layer that makes up the majority of the mass of the earth.
Hot air is ________ dense than cold air.
Less
The sphere that contains the layers of gasses surrounding the earth.
Atmosphere
What is the main cause of weather and climate?
Uneven heating of earth's surface.
When two air masses run into each other, the boundary between them is called ________
a front
The thinnest layer of the earth.
Crust
Salt water is ___________ dense than fresh water.
More
The sphere that contains all of the water on earth.
Hydrosphere
What is the difference between weather and climate?
weather is the minute by minute changes in earth’s atmosphere while climate refers to patterns of weather over long periods of time in a specific region
Which type of front is likely to cause clear skies?
Stationary Front
Made of liquid iron and nickel and is responsible for the earth's magnetic field.
Outer core
Name 3 places where convection currents happen.
Ocean, atmosphere, lithosphere
The sphere that contains earth's landforms and all rock and dirt on the earth's surface.
Name 3 main factors of climate
Latitude, elevation/altitude, topography
Which type of front involves 3 different air masses?
Occluded Front
Made of solid iron and nickel and is the hottest layer of the earth.
Inner core
Why is ocean water more salty near the north pole and south pole?
Because when ocean water freezes in icebergs or ice caps, it leaves the salt behind making the water around it more salty.
The sphere where tectonic plate movement occurs. Includes the crust and the upper part of the mantle.
Lithosphere
Name 4 main factors of weather.
Temperature, humidity, air pressure, precipitation, wind
Air always moves from _________ pressure to __________ pressure zones.
High to low
Explain why it is hard to study about the layers of the earth below the crust.
Because the extreme heat and pressure as you dig down into the earth makes it impossible to dig very far.
What is the Coriolis Effect?
Curved wind patterns caused by the convection currents in the air and the rotation of the earth.
The sphere that contains all the frozen water on earth and the majority of the freshwater supply on earth.
Cryosphere
Which type of front is likely to cause gentle rain showers over a long period of time?
warm front
