Some animals protect coral reefs while others harm them. The Crown of Thorns Starfish came to a certain coral reef in the Pacific Ocean in 2015. The graph shows the size of the reef over time. Which statement about the size of the reef is supported by the data in the graph?

• The number of starfish in the area dropped after 2015.

• The starfish made the coral reef smaller from 2015 to 2018.

• The coral reef was healthy and growing from 2013 to 2018.

• The coral reef lost more than 2,000 meters from 2015 to 2018.

Students dropped a ball of dough from different heights and timed how long it took the ball to fall to the floor. They then drew the shape of the dough after it hit the floor. Their data are in the table.Based on the data collected, which two conclusions can students make about the speed and energy of the dough when it hit the floor?

• The dough had the fastest speed and the least kinetic energy when dropped from a height of 1 meter.

• The dough had the slowest speed and the most kinetic energy when dropped from a height of 1 meter.

• The dough had more speed and kinetic energy when dropped from a height of 2 meters than from 1 meter.

• The dough had less speed and kinetic energy when dropped from a height of 4 meters than from 3 meters.

• The dough had the fastest speed and the most kinetic energy when dropped from a height of 5 meters.

The map on the left shows the Andes mountain range in South America. The map on the right shows the Himalayan mountain range in India. The mountain ranges in these maps are evidence that mountain ranges:

• form at the border of two tectonic plates.

• form in the middle of a tectonic plate.

• exist on their own separate tectonic plates.

• represent the formation of new tectonic plates.

A photograph of a river delta is shown.

Which statement correctly describes the delta in the photograph?

• Deposition is causing the delta to become narrower over time.

• Deposition is causing the delta to become bigger over time.

• Erosion is causing the delta to become smaller over time.

• Erosion is causing the delta to become wider over time.

Two friends live near each other. Friend 1 calls Friend 2. Friend 1 talks into the cell phone. The cell phone changes the sound of Friend 1's voice into digital information. The digital information goes to the nearest radio tower as radio waves. The radio tower sends those raido waves to Friend 2's cell phone. Friend 2's cell phone chages the radio waves back into digital information. The digital information is then turned into sound so that Friend 2 can her Friend 1.

Why are Friend 1's sounds turned into digital information?

• in case people do not speak clearly

• so the sounds can be sent as radio waves

• so Friend 2 can communicate with the tower

• in case the radio waves do not reach Friend 2's cell phone
