Q: Answer the following question given this paragraph: An explosive eruption produces huge clouds of volcanic ash. Chunks of the volcano fly high into the atmosphere. Explosive eruptions can be tens of thousands of times as powerful as an atomic bomb ( Figure below ). Hot magma beneath the surface mixes with water. This forms gases. The gas pressure grows until it must be released. The volcano erupts in an enormous explosion. Q: Explosive eruptions associated with what can be tens of thousands of times as powerful as an atomic bomb? Choices: - forest fires - hurricanes - earthquakes - volcanoes A:
A: volcanoes

Q: Answer the following question given this paragraph: Stars are born in clouds like the one in the picture. Gravity pulls material together. When it is extremely dense, it begins nuclear fusion. That is, it becomes a star. We can see places where stars are being born right now. Of course, it takes light a long time to travel to us. So what we see right now may have happened many millions or even billions of years ago. Q: Stars are born in clouds, and they form and grow dense due to what force? Choices: - kinetic energy - Big Bang theory - coreolis effect - gravity A:
A: gravity

Q: Answer the following question given this paragraph: Cellular slime molds are used as model organisms in molecular biology and genetics. They may be the key to how multicellular organisms evolved. Can you explain why?. Q: What are used as model organisms in molecular biology and genetics? Choices: - electromagnetic slime molds - convergent slime molds - weather slime molds - cellular slime molds A:
A: cellular slime molds

Q: Answer the following question given this paragraph: Constructive interference occurs when two waves combine to create a larger wave. This occurs when the peaks of two waves line up. Q: What is it called when two waves combine to create a larger wave? Choices: - Destructive Interference - consistent interference - wave propagation - constructive interference A:
A: constructive interference
