Types of Energy
Does an unmoving object have kinetic or potential energy?
Potential
Two dump trucks travel down a road at the same speed. One is loaded with gravel, and the other is empty. Which one has more kinetic energy?
The gravel-filled truck has more kinetic energy because it has more mass.
Large quantities of natural gas are available just below Earth's surface in many locations around the world. Why is natural gas still considered "non-renewable?"
Because it is not quickly or easily replaced (it takes millions of years to form)
What TOOL is used to measure air pressure?
A Barometer
The area where 2 or more air masses meet and do not mix is called a ______.
Front
If you compress a spring and hold it, you have created an example of _______ ________ energy. (two words)
Elastic Potential
As a roller coaster car descends a hill, it speeds up as it converts (A) ______ energy into (B) _______ energy.
(A) potential --> (B) kinetic
Different than a "renewable resource," an energy source (like the sun or wind) that is "available at the same rate, and expected to never run out" is called ___________.
Sustainable
Name THREE of the four factors that determine the weather:
Temperature, Air Pressure, Wind (speed and/or direction), and Humidity
What are the 4 types of fronts?
Cold, Warm, Stationary and Occluded
Another name for heat is ______________ energy, which is measured by determining the object's temperature.
Thermal
The energy in any changing situation is never "lost" - rather it is converted into what?
Other types of energy
A natural resource that can be replaced (like trees or cotton) is called a _____________ resource.
Renewable
The direction weather moves on a map is typically from the _____ toward the ______. (Use cardinal directions)
West --> East
What causes air to move in our atmosphere?
UNEVEN HEATING of Earth's surface (and a difference in air pressures) cause CONVECTION currents to form
Both a battery and an apple contain which type of potential energy?
Chemical
The amount of kinetic energy an object has is determined by what TWO characteristics?
(1) Mass and (2) Speed (or Velocity)
Identify (2) drawbacks unique to generating electricity using solar or wind power instead of fossil fuels.
More expensive to install, not always available 24-hours a day, etc.
A forecast of cooler temperatures, thunderstorms and rain indicates that a _____ front and a ______ pressure system are approaching.
cold AND low
Identify this convection phenomenon: "Warmer air over the ocean rises during the night, and then falls over the cooler land, creating THIS specific type of breeze."
Land Breeze
Positive charges are pulled toward negative charges. When they are held apart and aren't allowed to move together, they create ________ _________ energy. (two words)
Electric Potential
Identify the type of heat transfer in each of the following: (A) opening a window in a hot room, (B) a lizard suns itself, (C) placing an icepack on a sprained ankle
(A) convection (B) radiation (C) conduction
The positive human impact of reducing, re-using, and recycling materials are all ways "to prevent the wasteful use of a resource," - also known as this one-word environmental goal:
Conservation
Describe (in detail) the symbol used for an occluded front on a weather map:
It has both pointed and rounded symbols on the same side of the line the front is moving (often in purple)
Identify (3) types of severe weather caused by changing weather patterns in the atmosphere
Tornadoes, Hurricanes, Blizzards, Thunderstorms
