Two students designed an experiment to test the effects of force on an object. They stood on opposite sides of a large box and then they applied a push to the box. The box moved to the right
Why did the box move to the right?

B Gravity was stronger on the left so the box moved to the right
C The pushing force was greater on the left so the box moved to the right
D The friction was less on the left so the box moved to the right
C The pushing force was greater on the left so the box moved to the right

How do river deltas change over time?
A More and more sediments build up around the delta. The river develops more branches.
B Water erosion continues. The ocean wears away the land, and the coastline recedes.
C Water erosion continues. Smaller river branches disappear, and the main branch becomes deeper.
D Fewer sediments are deposited into the river system. The river valley dries up, and vegetation dies out.
A More and more sediments build up around the delta. The river develops more branches.

People rely on electricity to do many jobs. A source of energy is needed to produce this electricity. One of the ways this energy can be created is from moving water. Hydroelectric power plants are used for this purpose. Water flows naturally in a river. When you build a dam to hold back the water, it creates a lake with a large amount of water. Some water is then allowed to flow through small tunnels in the dam. This creates more force in the water flow, which turns turbines. The movement of the turbines turns a generator that produces electricity. Hoover Dam is an example of a dam that produces a large amount of hydroelectric power for the western part of the country.
According to the above electricity reading passage and diagram, using water to turn the turbines in a hydroelectric power plant is an example of using what form of energy to produce electricity?
A Light
B Mechanical
C Thermal
D Electrical
B Mechanical
