Which of the following is a difference between a meteor and a comet?
-
Meteors are mostly made up of ice.
No. Meteors are made up of rock or iron, Comets are mostly made up of ice. -
Only comets have a visible tail.
No. A meteor is a meteoroid that has entered our atmosphere. As it burns, it also produces a tail. -
Meteors seem to move faster because they are closer.
Yes. Meteors are entering our atmosphere, so they are much closer to us that a distant comet. That makes them seem to move much faster. -
Comets are smaller than meteors.
No. Meteors are small, often the size of a grain of sand. Comets are much larger.

Incandescent light bulbs use electrical energy to produce light energy, but it is not a direct transformation. Instead, the electrical energy is changed to a different form of energy, and then to light.
Electricity → ? → Light
What form of energy does the "?" represent?
-
Sound
No. Electrical energy can be transformed into sound energy, but that would not cause the bulb to light. -
Thermal
Yes. As electrical energy flows through the filament, resistance changes the electrical energy into thermal energy. When the filament gets hot enough, some of the thermal energy is converted into light. -
Radiation
No. The electrical energy is not transformed into radiation. -
Friction
No. The electrical energy is not transformed into friction.

The large cracks in this rock are called expansion cracks. As the overlying rock erodes away, the rock expands, causing the cracks. The cracks are an example of:
-
Erosion
No. Erosion means that the pieces of rocks are being carried away. The overlying rocks have been eroded, but the cracks are not carrying the pieces to a new location. -
Weathering
Yes! As the rocks expand unevenly, tension builds up. When there is enough stress, the rocks break. That breaking of large rocks into smaller pieces is called weathering. -
Both erosion and weathering
No. The rocks are being broken (weathering), but the pieces are staying in place, so there is not erosion. -
Neither erosion nor weathering
No. The cracks show that the rocks are breaking, which is weathering..

The wood in this pile will be reduced to this much ash when it is burned. What happens to the rest of the mass from the wood?
-
It was converted into energy.
No. Burning does not convert matter into energy. -
It evaporated.
No. While any moisture in the wood may have evaporated, wood itself does not evaporate. -
It was converted into water and carbon dioxide.
Yes! Burning converts the cellulose in wood into water vapor and carbon dioxide. The white ash that is left behind is made up of the minerals and nutrients which were taken in by the plant's roots. -
The matter is still there. It just got smaller.
No. If all of the matter was still there, the mass and weight would still be the same. The ash is much lighter than the wood, because the water vapor and carbon dioxide are now part of the air of the room. Still, if we could weigh all of the ash, water vapor, and carbon dioxide, the total mass would still be the same.
