Q: Q: Why are continents unable to be pushed down into the mantle by plate boundaries? Read this paragraph and choose the correct option from the provided answers: Most of the world's largest mountains form as plates collide at convergent plate boundaries. Continents are too buoyant to get pushed down into the mantle. So when the plates smash together, the crust crumples upwards. This creates mountains. Folding and faulting in these collision zones makes the crust thicker. Choices: - gravity - surface tension - density - buoyancy A:
A: buoyancy

Q: Q: There are two basic body plans in cnidarians which are called the polyp and what else? Read this paragraph and choose the correct option from the provided answers: There are two basic body plans in cnidarians. They are called the polyp and medusa. Both are shown in Figure below . The polyp has a tubular body and is usually sessile. The medusa (plural, medusae ) has a bell-shaped body and is typically motile. Some cnidarian species alternate between polyp and medusa forms. Other species exist in just one form or the other. Choices: - hydra - spore - stoma - medusa A:
A: medusa

Q: Q: Four electron groups orient themselves into what shape that has four faces? Read this paragraph and choose the correct option from the provided answers: Four electron groups orient themselves in the shape of a tetrahedron. Choices: - spherical - multicellular - circular - tetrahedron A:
A: tetrahedron

Q: Q: What does the heat energy affect in the atmosphere? Read this paragraph and choose the correct option from the provided answers: How do the differences in energy striking different latitudes affect Earth? The planet is much warmer at the equator than at the poles. In the atmosphere, the differences in heat energy cause winds and weather. On the surface, the differences cause ocean currents. Can you explain how?. Choices: - gravity and precipitation - erosion and condensation - density and humidity - winds and weather A:
A: winds and weather
