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:

  1. Erosion

    No. Erosion means that the pieces of rocks are being carried away. The lichen is dissolving the rock, but not carrying it away.

  2. Weathering

    Yes! Lichens cause quite a bit of weathering in rocky areas.

  3. Both erosion and weathering

    No. The rock is not being moved, so it is not erosion.

  4. Neither erosion nor weathering

    No. As the lichen dissolves the rock, that is an example of weathering.

Rainbows are produced by:

  1. Refraction

    Partly correct. Light entering the raindrop is reflected off of the back surface.

  2. 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.

  3. 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.

  4. Neither reflection no refraction

    No. One or both take part in producing the rainbow.

Cannonball Jelly fish are excellent swimmers, and Portly Spider Crabs often hitch a ride on them. What type of relationship is that?

  1. mutualism

    No. In mutualism, both organisms benefit. The jellyfish gets no benefit from the crab's hitchhiking.

  2. commensalism

    Yes. In commensalism, one organism (the crab) benefits, and the other (jellyfish) is not affected. The crab gets free transportation, and the jellyfish is not helped or harmed.

  3. parasitism

    No. For parasitism, one organism benefits, and the other is harmed. Neither the crab nor the jellyfish is harmed by this relationship.

  4. predation

    No. In predation, one organism eats another. Neither the crab nor the jellyfish gets eaten in this relationship.

While this spoon appears to have a broken handle, it is just the result of how the water affects the light. This is an example of:

  1. Refraction

    Yes! Refraction bends light as it moves from one substance to another. As the light passes from the water to the air, its path is changed, making it appear that the spoon is broken.

  2. Reflection

    No. While some light is reflected from the glass, it is not responsible for the bending of the light.

  3. Absorption

    No. The water and glass are both clear, telling us that very little of the light is being absorbed. Absorption does not bend the light.

  4. Diffusion

    No. Diffusion is the scattering of light as it is reflected in many different directions. Diffusion would make the image cloudy and blurry.

This is the density column from the Making a Density Column video. Notice that the olives are floating at the boundary between the water and the corn syrup. What does that tell us?

  1. The olives are less dense than the water, and more dense than the corn syrup.

    No. If the olives were less dense than the water, they would float on top of the water layer.

  2. The water is denser than the olives.

    No. If the water was denser than the olives, then the olives would float on top of the water layer.

  3. The corn syrup is less dense than the olives.

    No. If the corn syrup was less dense than the olives, the olives would sink all the way to the bottom.

  4. Olives are denser than water, and less dense than corn syrup.

    Yes! Because the olives are denser than water, they sink to the bottom of the water layer. Because they are less dense than corn syrup, the olives float on top of the corn syrup layer.
