a form of energy that is molecular activity which flows from one substance or object to another.
What is Heat?
100
the process by which heat is trrapped in the atmosphere by gases that form a blanket around Earth, moderating its temperature so that live is possible.
What is the Greenhouse Effect?
100
moving air

What is the angle of Earth's tilt?
200
an instrument used to measure the amount of molecular activity in an object or substance; it tells how hot or cold something is.
What is a thermometer?
200
the troposphere
What is the lowest layer of Earth's atmosphere where we live and weather happens?

What is the number of days it takes for Earth to orbit the sun?
300
radiation, conduction, and convection
What are the three types of heat transfer?
300
sun's rays carrying light and heat travel on these to the Earth's surface, heating through the process of radiation
What are electromagnetic waves?
300
sailors traveled along these to power their ships
What are the trade winds?

the pressure of an air mass is affected by adding or taking this away
What is heat?
400
The weight of air masses
What is pressure?

greenhouse gases
What are the gases in the atmosphere that trap energy called?
500
Earth's tilt on it's axis, position in its revolution around the sun, and the angle at which the sun's rays hit the planet
What are the 3 major reasons for the seasons?
500
the direct transfer of heat from one substance to another that it is touching
What is conduction?
500
cold air sinks down from the poles towards the equator while warm air rises from the equator towards the poles
What are global convection currents?
