Question

reading passage
earth’s atmosphere has several layers that influence weather and climate. the lowest layer, called the troposphere, is where clouds, snow, rain, and winter storms occur. this layer contains most of the air and greenhouse gases that affect temperature.
above the troposphere is the stratosphere, which contains the ozone layer. the ozone layer absorbs harmful ultraviolet (uv) radiation from the sun. although winter storms do not form in the stratosphere, this layer helps protect life on earth.
changes in atmospheric layers can influence storm strength, temperature, and precipitation patterns during winter
multiple choice: circle the best answer

a. stratosphere b. troposphere c. mesosphere d. thermosphere

1. the lowest atmospheric layer is the:

a. troposphere b. stratosphere c. mesosphere d. exosphere

1. which layer contains the ozone layer?

a. troposphere b. stratosphere c. mesosphere d. core

1. what does the ozone layer absorb?

a. infrared radiation b. heat c. uv radiation d. visible light

1. weather happens mainly because of:

a. air movement in the troposphere b. earth’s rotation
c. ocean tides d. solar flares

1. which layer contains greenhouse gases?

a. stratosphere b. troposphere c. mesosphere d. thermosphere

1. ozone is made of:

a. two oxygen atoms b. three oxygen atoms c. carbon dioxide d. nitrogen

1. damage to the ozone layer causes:

a. less uv reaching earth b. more uv reaching earth
c. more snowstorms d. cooler temperatures

Explanation:

Question 1

The passage states "The lowest layer, called the troposphere, is where clouds, snow, rain, and winter storms occur." So winter storms occur in the troposphere.

From the passage: "The lowest layer, called the troposphere...", so the lowest atmospheric layer is the troposphere.

The passage says "Above the troposphere is the stratosphere, which contains the ozone layer." So the stratosphere contains the ozone layer.

Answer:

B. Troposphere
