They are organisms that use energy from the Sun to make their own food.
What are producers?
100
The process of breaking down rocks.
What is weathering?
100
The weight of air in an area.
What is air pressure?
100
distance divided by time
What is speed?
100
It is a collection of millions of tiny water droplets and ice crystals.
What is a cloud?
200
The process by which plants make their own food.
What is photosynthesis?
200
These are examples of weathering.
What are water, ice, wind, and gravity?
200
The air heats up, rises, and becomes less dense (so it's lighter).
What happens in areas of low pressure?
200
speed and direction
What is velocity?
200
The force that acts on an object to stop its motion.
What is friction?
300
These ecosystems are found in shallow parts of the ocean where the water is very warm and there is plenty of sunlight. There are many different ypes of marine animals that live there.
What are coral reefs?
300
Looping changes of direction in a river or stream.
What are meanders?
300
This type of front is formed when two cold air masses move toward one another and push the warmer air between them upward. This type of front brings cool temperatures and plenty of rain and snow.
What is an occluded front?
300
This kind of energy is used to make a water wheel work.
What is mechanical energy?
300
It is the product of the mass and velocity of an object.
What is momentum?
400
These are bodies of water found in areas wehre freshwater from rivers and streams and salt water from the ocean meet.
What are estuaries?
400
A low, flat piece of land at or near the mouth of a river. They are formed by deposition as the river slows down.
What is a delta?
400
This breeze forms when the mountain air cools down faster than the valleys at night. The cool air sinks and flows down the mountain.
What is a mountain breeze?
400
I would use electrical energy in order to make the light energy and heat energy for this to work.
What would you use to make a light bulb work?
400
This is flat land near a river, formed by deposition during floods.
What is a floodplain?
500
During this cycle, animals release carbon into the air through respiration, , and the carbon dioxide is then used by plants for photosynthesis.
What is the carbon cycle?
500
Land clearing, planting crops, and building dams are some examples.
What are some examples of how humans change the land?
500
These zones are found between the polar and tropical zones.
Where are temperate zones located?
500
These are ways a designer would show his/her work before making the real thing. (List 3 ways!)
Descriptions, drawings, and models are all ways designers can do what?
500
It is all the organisms that live in the same area.
