Weather 1.1

A scientist compared the atmospheric composition of a newly discovered planet to the atmosphere of Earth.

Which conclusion about the unknown planet can be made by using the information provided?

• It is not suitable for animals.

• It will sustain a small human population.

• It has enough oxygen for small mammals.

• It has many carbon-dioxide-releasing organisms.

The temperature of the stratosphere increases with altitude because of the presence of

• nitrogen.

• water vapor

• ozone

• carbon monoxide.

Which gas makes up the greatest percentage of Earth’s atmosphere?

• argon

• nitrogen

• nitrous oxide

• carbon dioxide

On Mount Everest the temperature decreases as the altitude increases. The summit of this mountain is in which atmospheric layer?

• mesosphere

• stratosphere

• thermosphere

• troposphere

Why does the troposphere experience the greatest amount of atmospheric pressure compared to the other atmospheric layers?

• It produces the ozone layer.

• It has the highest temperatures.

• It contains a high concentration of gas particles.

• It is the region in which weather occurs.

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

• the exosphere, which is the outermost layer

• the troposphere, which is the lowest layer

• the thermosphere, which has the highest temperature

• the stratosphere, which contains a sub-layer of ozone

Which explains why most of the rain that falls comes from the ocean?

• The majority of evaporation takes place over the ocean.

• The majority of precipitation takes place over the ocean.

• Most rivers deposit freshwater into the ocean.

• Most clouds form near or over the ocean.

Which statement explains what will MOST likely happen to the hydrosphere in an area where air temperatures increase?

• Earthquake intensity will decrease

• Mountain formation will decrease.

• Rock weathering will increase

• Evaporation will increase.

Storms transport water in the form of rain. The energy that starts this process comes from which of these?

• the oceans

• the Sun

• clouds

• Earth

Which two things interact MOST in the water cycle?

• oceans and the Moon

• oceans and the Sun

• lakes and the Moon

• lakes and the Sun
