Answer the following question given this paragraph: Upwelling also takes place along the Equator. Winds blow the surface water north and south. This leaves a void that deep water can upwell into. The nutrients rise to the surface and support a great deal of life in the equatorial oceans. Q: Deep water filling a void caused by surface winds blowing water north and south is known as? Choices: - downwelling - surface current - divergence - upwelling A:
upwelling
Answer the following question given this paragraph: Humid subtropical climates are found on the eastern sides of continents between about 20 and 40 latitude. The southeastern U. S. has this type of climate. Summers are hot and humid, but winters are chilly. There is moderate rainfall throughout the year. Pine and oak forests grow in this climate ( Figure below ). Q: Where can you find humid subtropical climates? Choices: - between 20 and 40 degrees longitude - between 40 and 60 degrees latitude - between 40 and 60 degrees longitude - between 20 and 40 degrees latitude A:
between 20 and 40 degrees latitude
Q: Answer the following question given this paragraph: The space shuttleand any other rocket-based systemuses chemical reactions to propel itself into space and maneuver itself when it gets into orbit. The rockets that lift the orbiter are of two different types. The three main engines are powered by reacting liquid hydrogen with liquid oxygen to generate water. Then there are the two solid rocket boosters, which use a solid fuel mixture that contains mainly ammonium perchlorate and powdered aluminum. The chemical reaction between these substances produces aluminum oxide, water, nitrogen gas, and hydrogen chloride. Although the solid rocket boosters each have a significantly lower mass than the liquid oxygen and liquid hydrogen tanks, they provide over 80% of the lift needed to put the shuttle into orbitall because of chemical reactions. Q: What do rocket-based systems use to propel itself into space? Choices: - water reactions - hydrogen reactions - nuclear reactions - chemical reactions A:
A: chemical reactions

Answer the following question given this paragraph: We have been able to take pictures of only a few exoplanets. Most are discovered because of some tell-tale signs. One sign is a very slight motion of a star that must be caused by the pull of a planet. Another sign is the partial dimming of a star's light as the planet passes in front of it. Q: What celestial body is often discovered because it causes a star to move or to dim? Choices: - satellite - asteroid - comet - exoplanet A:
(Answer)
exoplanet
