Earth's Atmosphere

Earth's Atmosphere

Vocabulary:

System - a group of interacting parts, where each part influences the whole

Multiple Choice

What is a system?

• a group of influences

• a group of influencing part.

• a group of interacting parts

1 - Weather in the Earth Systems

What are the four spheres of Earth?

atmosphere, geosphere, biosphere, hydrosphere

The atmosphere, geosphere, biosphere and hydrosphere all interact with each other affecting the whole planet.

Energy from the sun is added to the Earth system and the movement of this energy causes weather.

Multiple Choice

Which one is not one of the 4 spheres of Earth?

• hydrosphere

• biosphere

• troposphere

• geosphere

• atmosphere

Multiple Choice

TRUE or FALSE, the four spheres do not interact with each other.

• TRUE

• FALSE

Multiple Choice

Where does the energy come from that causes weather to occur?

• the Moon

• Mars

• Venus

• the Sun

2 - Composition of Earth’s Atmosphere 

Aerosols are microscopic solid particles in the atmosphere that came from natural and human processes.

The following gases make up our atmosphere:

Nitrogen 78%,

oxygen 21%, 

argon / carbon dioxide / aerosols 1%

Multiple Choice

__________ are microscopic solid particles in the atmosphere that came from natural and human processes.

• atmospehre

• aerosols

• asteroid

Multiple Choice

Which gas makes up most of our atmosphere?

• nitrogen

• oxygen

• carbon dioxide

• argon

Multiple Choice

Which gas makes up 21% of our atmosphere?

• nitrogen

• oxygen

• carbon dioxide

• argon

3 - Structure of Earth’s Atmosphere 

The layers of the atmosphere starting on Earth's surface and extending into outer space are as follows: Troposphere, stratosphere, mesosphere, thermosphere, exosphere

Scientists use composition, distance between particles, and temperature to determine the layers of the atmosphere.

The thinnest layer of our atmosphere is the troposphere and the thickest layer is the exosphere.

Multiple Choice

Which layer of the atmosphere is closest to the Earth's surface?

• troposphere

• stratospehre

• mesosphere

• exosphere

Multiple Choice

Which layer of the atmosphere is the farthest from the Earth's surface?

• troposphere

• stratospehre

• mesosphere

• exosphere

Multiple Choice

Which pair are the thinnest layer and the thickest layer of our atmosphere?

• mesosphere / stratosphere

• thermosphere / exosphere

• troposphere / exosphere

• troposphere / thermosphere

4 - Elements of Weather 

Weather is what is happening in the atmosphere at a specific place and time.

Climate is weather patterns in a region over a long period of time.

These are the following measurable factors that determine weather: air temperature, air pressure, wind, humidity, and precipitation

Multiple Choice

What do we call the atmospheric conditions at a specific place and time?

• weather

• climate

• precipitation

Multiple Choice

What do we call weather patterns in a region over a long period of time?

• weather

• climate

• precipitation

Multiple Choice

Which of the following is one of the measurable factors used to determine weather?

• oxygen

• ozone

• humidity
