Weather Part 1

When cold air is at the top of the mountain, the air 

• Will flow toward ares of lower pressure in valleys 
• will flow toward areas of higher pressure in valleys
• is considered to be less dense than warmer air
• is considered to be free of oxygen atoms 

When is the MOST energy transferred from the Sun to water in the water cycle?

• •during collection
• •during evaporation
• •during condensation
• •during precipitation

In which layer of Earth’s atmosphere does weather occur?

• mesosphere
• stratosphere
• thermosphere
• troposphere

Barometric pressure has been dropping all day. What weather conditions will most likely occur?

• •sunny weather
• •stormy weather
• •calm weather
• •hot weather

Which of these MOST likely causes winds to blow on Earth?

• •The Earth spins quickly, causing the air to blow around.
• •The gravity of Earth and the Moon push and pull the air.
• •Warm air rises and cool air falls toward Earth’s surface.
• •Ocean waves push air onto the shore and across Earth’s surface.

One substance found on Earth is more stable as an elemental gas than as part of a solid compound. As a result, this substance is very abundant in the atmosphere. Which substance exhibits these traits?

• •argon
• •chlorine
• •nitrogen
• •oxygen

The Coriolis Effect deflects wind direction. How does this process impact ocean surface currents?

• The wind deflects the currents to the right in the Northern Hemisphere and to the left in the Southern Hemisphere
• •The wind deflects the currents to the left in the Northern Hemisphere and to the right in the Southern Hemisphere.
• •The wind deflects the currents to the left in both hemispheres.
• •The wind deflects the currents to the right in both hemispheres.

Which of these BEST explains the cause of convection currents in Earth’s atmosphere

• •Heat from Earth’s core heats the land only at the equator.
• •Glaciers moving away from the poles cool Earth unevenly.
• •Sunlight is more concentrated in some places on Earth than others.
• •The light and heat reflected from the Moon varies as the Moon changes phases.

Which of the following are narrow belts of strong winds found in the upper troposphere?

• •doldrums
• •westerlies
• trade winds
• •jet streams

How does the ocean affect weather on Earth?

• •Waves in the ocean push on the air above, which causes storms to form.
• Salt in the ocean dries the air above, causing the air to heat up and rise
• •Water evaporates from the ocean, causing clouds to form and send rain back to Earth.
• •Water in the ocean is cooler than the air above, which causes the air temperature to remain low.
