This is a lichen, which is actually a fungus and an algae living together. As it grows, it produces chemicals which dissolve some of the rock it grows on. This is an example of:
-
Erosion
No. Erosion means that the pieces of rocks are being carried away. The lichen is dissolving the rock, but not carrying it away. -
Weathering
Yes! Lichens cause quite a bit of weathering in rocky areas. -
Both erosion and weathering
No. The rock is not being moved, so it is not erosion. -
Neither erosion nor weathering
No. As the lichen dissolves the rock, that is an example of weathering.

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.

Rainbows are produced by:
-
Refraction
Partly correct. Light entering the raindrop is reflected off of the back surface. -
Reflection
Partly correct. As the light passes from air to water, and from water to air, the light is bent or refracted. Different colors are refracted different amounts, separating the colors. -
Both reflection and refraction
Correct! When you see a rainbow, the sun will always be behind you. (There are other, similar looking phenomena which you see when facing the sun, but they are not rainbows.) The sunlight enters each raindrop, is refracted (bent). Different colors are refracted different amounts. When the light hits the far side of the raindrop, part of it goes on through, and part of it is reflected back towards the sun (and towards you.) As it passes leaves the drop, the difference in density from water to air refracts (bends) the light even more, separating the colors into bands for the rainbow. -
Neither reflection no refraction
No. One or both take part in producing the rainbow.

Which of these sources of electricity is a renewable resource?
-
Coal
No. Coal is the fossilized remains of ancient plants, and it takes millions of years to form. -
Hydroelectric
Yes. The lake water that provides hydroelectric power is replenished every time it rains. -
Natural Gas
No. Natural Gas is a fossil fuel, and takes millions of years to form. -
Fuel Oil
No. Fuel oil comes from petroleum, which requires extremely long periods of time to form.

When water freezes into ice, its volume increases. What happens to its mass?
-
It increases.
No. When water freezes, it takes up more space, but the mass stays the same. -
It stays the same.
Yes. When water freezes, it expands to take up more space, but its mass stays the same. Mass is the measure of how much "stuff" is there. Freezing water does not create new water or add more "stuff". It just makes the water take up more space. -
It decreases.
No. The mass stays the same, even when the water freezes. -
Water does not have mass.
No. Everything that is made out of matter has mass.
