6th grade Science Review

Choose the TWO correct answers that describe how the ocean can affect weather and climate.

• It absorbs large quantities of heat.
• Its surface reflects heat back into the atmosphere.
• Its currents move heat from the equator to the poles.
• It causes circulation in the atmosphere by absorbing heat from the air.

Water in the atmosphere can change state from solid to liquid to vapor and back depending on temperature and pressure. Choose the TWO options that describe evaporation

• blade of grass is colder than the surrounding air
• warm, moist air rises and cools
• the sun rises and warms the atmosphere
• air flowing in from the ocean encounters a mountain
• puddle absorbs heat from the pavement below it

Normally, a low-pressure system is located over the western Pacific Ocean. During anEl Niño year, the low-pressure system moves to the eastern Pacific Ocean causing the main oceanic current to switch direction. Then the upwelling of nutrient-rich water decreases. Which characteristic is an indicator that an El Niño event is occurring?

• decrease in length of winter season
• decrease in temperatures at the poles
• increase in winds that blow Pacific Ocean currents
• increase in ocean temperatures in the eastern Pacific Ocean

Which of these best explains why the lake-effect snow generally stops in February?

• Ice layers are covering the lake.
• Air movements across the lake change direction.
• Land temperatures around the lake become colder.
• Air temperatures become warmer than lake temperatures.

Trade winds are surface winds that blow over the tropical ocean near the equator. Trade winds drive ocean currents in this region, moving warm water in an east-to-west direction, as shown in the picture. Every few years, some of the trade winds that blow directly over the ocean weaken. What changes would be most likely to occur next?

• Increasing ocean temperatures cause current speeds to increase.
• Ocean temperatures near the equator grow cooler and current speeds increase.
• Ocean temperatures near the equator grow cooler, causing heavy rainfall worldwide.
• The area of warm surface water near the equator increases in size and ocean currents slow or stop.
