Define
Define a current
A large stream of moving water that flows through the ocean.
Define thermal energy.
Thermal energy is the total kinetic and potential energy in an object.
What is a front?
The boundary where two air masses meet is called a front.
What are jet streams?
A band of high speed winds above earth.
Define climate
Climate is the long termed weather pattern in an area.
Define wind.
The movement of the air, especially in the form of a current of air blowing from a particular direction.
Explain the difference between a conductor and an insulator.
Materials that allow heat to travel through, like copper wires, are called conductors, while materials that inhibit electron flow, like rubber, are called insulators.
What is an atmosphere and how does it protect earth?
What is the difference between a sea breeze and a land breeze?
Land breeze is when the wind is coming from the land. Sea breeze is when the wind is coming from the sea.
Define latitude
Latitude refers to the distance of a location on Earth's surface from the equator in relation to the North and South poles.
Define air pressure.
Air pressure is the weight of air molecules pressing down on the earth.
Define friction.
The resistance that one surface or object encounters when moving over another.
What is the difference between humidity and relative humidity?
Relative Humidity is the amount of water vapor actually in the air, expressed as a percentage of the maximum amount of water vapor the air can hold at the same temperature. Humidity is the amount of water vapor in the air.
What are El Nino and La Nina.
El Niño events are associated with a warming of the central and eastern tropical Pacific, while La Niña events are the reverse, with a sustained cooling of these same areas.
What is the greenhouse effect?
The greenhouse affect is the process by which these gasses trap heat, keeping Earth warm.
Define dew point.
The temp at which condensation begins.
Explain why a steel spoon in a pot of hot soup would get hot.
It would get hot because the heat from the soup goes to the spoon, and because steel is a good conductor of heat. The process is called conduction.
Why is the water cycle important to us, and give me five examples of stages in the water cycle.
It is important because it is how water reaches plants, animals and us!
1. Precipitation
2. Evaporation
3. Condensation
4. Transportation
5. Desposition
What is the Coriolis effect, and how does it affect how we live today?
The Coriolis Effect makes things (like planes or currents of air) traveling long distances around the Earth appear to move at a curve as opposed to a straight line. It affects how science works and how planes and currents of air move.
Give three examples of how human activities can affect the climate change.
1. Burning fossil fuels.
2. Deforestation
3. Having abundant agriculture
Define an air mass and name the four types of air masses.
An air mass is a body of air with same temperature, humidity, and pressure.
1. Continental Polar
2. Continental Tropical
3. Maritime Polar
4. Maritime Tropical
1. When one toasts a marshmallow on a fire,, what type of heat transfer is it?
2. When one puts a steel spoon in a pot of hot soup and the spoon gets hot, what type of heat transfer is it?
3. Boiling water in a pot, and the hotter water goes up and the cooler goes down. What type of heat transfer is this?
1. Radiation
2. Conduction
3. Convection.
By which instrument is rain measured? And how does the instrument look like?
Rain is measured using a rain gauge. A rain gauge is an open ended tube that collects rain.
What are the differences in Convection, Radiation and Conduction?
Convection is the transfer of heat by the movement of a fluid. Radiation is the energy that is transferred by the air particles. Conduction is the transfer of heat between two substances that are in close contact.
Define Alternative Energy and give three examples of it.
1. Solar Power
2. Windmills
3. Hydropower
