Earth's Atmosphere

Which of these describes the atmosphere?

• A mixture of organic substances, nearly all which are visible and have odor.

• A mixture of many substances nearly all of which are invisible and odorless.

• A mixture of many visible substances from all four spheres of the Earth system.

• A mixture of a few inorganic substances, some of which are visible, dense, and odorless.

The layers that make up the atmosphere are

• warm air, cold air, and ozone.

• the biosphere, the hydrosphere, and the geosphere.

• clouds, aerosols, air particles, water, vapor, and sunlight.

• the troposphere, the stratosphere, the mesosphere, the thermosphere, and the exosphere.

Scientists who study the conditions and phenomena in the atmosphere are called

• astrologists.

• hydrologists.

• meteorologists.

• gastroenterologists.
