About 30% of the solar energy that reaches the atmosphere is reflected back into space. About 20% is absorbed by the air. What percentage reaches earth's surface?
50%
About 30% of the sun's incoming energy never reaches Earth's surface because it is ______.
reflected back out into space
convection current
the movement of a fluid, caused by differences in temperature, that transfers heat from one part of the fluid to another
In which layer of the atmosphere does most of Earth's weather occur?
the troposphere, which is the lowest layer
What powers all thunderstorms?
warm, moist air
The atmosphere contains minor amounts of gases like (select all that apply)
water vapor, argon, carbon dioxide
Select the location on the weather map to answer the question. In which location, on the map, are thunderstorms most likely to occur within the next 24 hours (tomorrow)?
1
Which numbered part of the picture represents the way that the energy from the Sun reaches the Earth?
1
Which two processes do the arrows labeled 1 and 2 best represent in this diagram?
1: absorption and 2: reflection
Juan noticed that sunny skies suddenly became stormy. Which most likely happened when the weather changed in this way?
Air pressure dropped
_________________ first decreases and then increases as the altitude increases.
Air temperature
Which graph best illustrates the relationship of altitude and temperature in the lowest layer of the atmosphere of Earth?
As you increase altitude the temperature drops
How is energy distributed in ocean water?
Convection
Conduction
Form of heat transfer where heat energy is directly transferred between molecules through molecular collisions or direct contact.
What conclusions can you make about the color of surface and the amount of heat it absorbs?
Light-colored surfaces reflect sunlight, therefore the temperature does not increase significantly
The presence of greenhouse gases in Earth's atmosphere is important to Earth's ability to support human life. How would Earth be different without greenhouse gases in its atmosphere?
More heat from solar radiation would escape into space.
According to this map, a cold front is moving through which state?
Oregon
How does the arrangement of the air molecules found in the troposphere compare to the arrangement of those found in the thermosphere?
The air molecules are closer together in the troposphere and are farther apart in the thermosphere.
High-pressure systems stop air from rising into the colder regions of the atmosphere where water can condense. What will most likely result if a high-pressure system remains in an area for a long period of time?
drought
Cumulonimbus clouds often form along cold fronts. Which type of weather is most likely to occur along a cold front?
rain with possible severe thunderstorms
Based on this map, the weather in Ohio on the following day will most likely be
rainy.
Which statement correctly describes a difference between the mesosphere and the stratosphere?
The mesosphere contains fewer oxygen molecules than the stratosphere
Which of the below statements is only true for hurricanes and not tornadoes?
They form only over warm oceans
Why are scientists concerned with ozone depletion in the upper atmosphere?
because it allows ultraviolet radiation to reach Earth's surface
Which of these gases, on average, has the lowest volume in the atmosphere of Earth?
carbon dioxide
Which condition is associated with most warm fronts?
cloud formations bringing precipitation
What type of weather is normally related to a low pressure?
cloudy with rain
Rising warm air leads to the formation of
hurricanes.
Some of the sun's energy is absorbed by Earth's surface and released back into the atmosphere as
infrared radiation
What gas does wedge X represent?
nitrogen
The temperature of the stratosphere increases with altitude because of the presence of
ozone
