What is chemical potential energy?

Back

Chemical potential energy is the energy stored in the bonds of chemical compounds, like atoms and molecules. It can be released or absorbed during a chemical reaction.

What happens to chemical potential energy when a battery-operated device is turned on?

Back

The chemical potential energy in the battery is converted into electrical energy, resulting in a decrease in chemical potential energy.

What is the relationship between the distance a rubber band is stretched and the speed of a toy truck?

Back

When the distance the rubber band is stretched is increased, the speed of the toy truck also increases, demonstrating the principle of potential energy conversion to kinetic energy.

What type of biome is characterized by large trees and high precipitation?

Back

Rain forest is characterized by large trees and an average yearly precipitation of 75-150 centimeters.

Front

What is wind energy?

Back

Wind energy is the energy obtained from the movement of air (wind) that can be converted into electricity using windmills.

Front

Why is wind energy considered a clean resource?

Back

Wind energy is considered clean because it is produced naturally and does not emit greenhouse gases during its use.

Front

What is a limitation of wind energy?

Back

Wind energy can only be collected in certain locations where wind conditions are favorable.

Front

What is the Gulf Stream current?

Back

The Gulf Stream current is a warm ocean current in the Atlantic Ocean that flows from the tropics to the northern latitudes.

Front

What happens to the Gulf Stream current as it moves toward the poles?

Back

As the Gulf Stream current moves toward the poles, it cools and becomes denser, causing it to sink.

Front

What is the significance of the density of water in ocean currents?

Back

The density of water affects the movement of ocean currents; warmer water is less dense and rises, while cooler water is denser and sinks.
