The picture shows a train as it approaches a hill. This train can only make it over the hill if it approaches at its top speed because it will lose speed as it climbs. What changes are taking place in the train’s potential and kinetic energy as it climbs the hill?

The train’s potential energy is increasing, and its kinetic energy is decreasing

The train’s potential energy is increasing, and its kinetic energy is increasing

The train’s potential energy is decreasing, and its kinetic energy is increasing

The train’s potential energy is decreasing, and its kinetic energy is decreasing

The picture shows a train as it approaches a hill. This train can only make it over the hill if it approaches at its top speed because it will lose speed as it climbs. What changes are taking place in the train’s potential and kinetic energy as it goes down the hill?

The train’s potential energy is decreasing, and its kinetic energy is increasing

The train’s potential energy is increasing, and its kinetic energy is increasing

The train’s potential energy is increasing, and its kinetic energy is decreasing

The train’s potential energy is decreasing, and its kinetic energy is decreasing

Why is the gravity on Earth greater than the gravity on Mars?

Mars has a smaller radius than Earth.

Earth has less surface area than Mars.

Earth has a thicker atmosphere than Mars.

Why does runner A have the fastest constant speed?

Because the angle of the line is more vertical

Because the angle of the line is more horizontal

Because the angle of the line is curved

Because the angle of the line is horizontal

Why does runner C have the slowest constant speed?

Because the angle of the line is more horizontal

Because the angle of the line is more vertical

Because the angle of the line is curved

Because the angle of the line is horizontal

According to the graph, which of the following statements is TRUE?

The object is stopped at 4 seconds

The object is moving away from the start during 7 seconds

Which of these parts of the Earth system are interacting when Florida’s orange trees grow?

biosphere, hydrosphere, and atmosphere

geosphere, cryosphere, and atmosphere

biosphere, hydrosphere, and cryosphere

cryosphere, atmosphere, and hydrosphere

How are the convection currents in the lava lamp different than convection currents in the atmosphere?

The earth gets its heat from the sun and the lava lamp gets its heat from the light bulb below.

warm air in the atmosphere sinks instead of rises

Convection cells in the atmosphere flow in the same direction instead of opposite

Cold air is less dense instead of being more dense.

What causes global convection currents

uneven heating of the Earth's surface

Which of the following is true about the unequal heating of land (sand) and water?

land/sand heats up and cools off faster than water

water heats up and cools off faster than land/sand

land and water heat and cool at the exact same rate

What causes winds to form on Earth?

uneven heating of the Earth by the sun
