The layer of Earth's atmosphere closest to Earth's surface is called the ________.
What is troposphere
100
the brightness of a star as viewed from Earth
What is apparent magnitude
100
Water moves from Earth's surface to the atmosphere through the process of _____.
What is evaporation
100
What are three ways the atmosphere benefits living things on Earth?
What is The atmosphere shields Earth from the harmful rays of the sun. It acts as an insulating blanket to keep Earth from becoming too hot or too cold. It also contains the oxygen living things things need to live. Other benefits may also be stated.
100
Objects from space rarely strike Earth because they ________.
What is usually burn up in the atmosphere
200
The air currents that cause weather are set in motion by _____.
What is the sun's energy
200
layer of Earth's atmosphere closest to Earth's surface
What is troposphere
200
Fossil fuels are formed from ______.
What is decaying organisms
200
Explain how Earth's landforms affect the weather.
What is When moist air moves over a mountain, the air becomes cooled and loses moisture as snow or rain. When air reaches the other side of the mountain it is dry. Large bodies of water make weather more temperate by retaining heat at night, raising the air temperature, and gaining heat slowly during the day, keeping the air temperature lower. Large bodies of water also add moisture to the air, increasing precipitation.
200
Why does one star seen in the night sky look larger than another, even though it is actually smaller and cooler?
What is The star that appears larger and brighter may be millions of kilometers closer to Earth than the fainter star.
300
The upward push water exerts on an object dropped into it is _____.
What is buoyancy
300
process in which liquid water changes to water vapor
What is evaporation
300
The force that causes objects from space to burn up in the atmosphere before they can strike Earth is _____.
What is friction
300
What kinds of information do meteorologists collect in order to predict tomorrow's weather?
What is Air temperature, air pressure, wind speed and direction, humidity, or movement of air masses. They would need both regional and global information.
300
attraction between two objects based upon mass and the distance between them
What is gravity
400
When warm front meets a cold front, _____.
What is the warm air mass rises
400
The force that causes objects from space to burn up in the atmosphere before they can strike Earth
What is friction
400
Gravity does not affect _____.
What is apparent magnitude
400
What does it mean if a meteorologist says tomorrow will be very humid day?
What is There will likely be a large amount of water vapor in the air.
400
What is the reason our planets have days and years of differing lengths?
What is each revolves around its axis at a different speed, which determines the length of its day. Each is a different distance from the sun, so the length of its orbit around the sun and, therefore, the length of its year are different.

______ is NOT a source of freshwater.
What is an ocean
