A student fills a bicycle tire with air on a very hot day. The next day, the temperature drops and it is much cooler. The student notices that the bicycle tire is almost flat. What best explains why the tire is flat?
The cooler temperature caused the air in the tire to expand, which put a hole in the tire, causing it to go flat.
The cooler temperature caused the air in the tire to freeze, making the tire flat.
The cooler temperature caused the air in the tire to contract, making the tire appear flat.
The cooler temperature caused the metal part of the bicycle to expand, putting a hole in the tire and making it go flat.
Which has the greatest effect on wind speed?
precipitation
cloud cover
wind direction
air pressure

Which best explains why sunlight is important in an ecosystem?
Sunlight is the main source of food in an ecosystem.
Sunlight helps the consumers in the ecosystem make their own food.
