Question: Answer the following question given this paragraph: Water becomes more dense when it is colder and when it has more salt. In the North Atlantic Ocean, cold winds chill the water at the surface. Sea ice grows in this cold water, but ice is created from fresh water. The salt is left behind in the seawater. This cold, salty water is very dense, so it sinks to the bottom of the North Atlantic. Downwelling can take place in other places where surface water becomes very dense (see Figure below ). Q: What is the name for the sinking of the dense, salty seawater in cold climates? Choices: - cyclones - jet stream - tidal activity - downwelling A:
Answer: downwelling

Answer the following question given this paragraph: Example 3.5 Calculating Projectile Motion: Hot Rock Projectile Kilauea in Hawaii is the world's most continuously active volcano. Very active volcanoes characteristically eject red-hot rocks and lava rather than smoke and ash. Suppose a large rock is ejected from the volcano with a speed of 25.0 m/s and at an angle 35.0 above the horizontal, as shown in Figure 3.40. The rock strikes the side of the volcano at an altitude 20.0 m lower than its starting point. (a) Calculate the time it takes the rock to follow this path. (b) What are the magnitude and direction of the rock's velocity at impact?. Q: Kilauea in hawaii is the world's most continuously active volcano. very active volcanoes characteristically eject red-hot rocks and lava rather than this? Choices: - greenhouse gases - carbon and smog - magma - smoke and ash A:
**Answer**
smoke and ash
