An increase in Earth's average surface temperature is caused by an increase in what? 

Greenhouse Gases 

100

In which layer does all weather occur? 

Troposphere 

100

It is thought that the Earth's Solar System formed approximately

4.5 billion years ago

How many hours are there in ONE rotation of Earth? 

23 hours 56 minutes 

24 hours 

23.9 hours

The Earth's Atmosphere supplies us with the ability to breathe. What is the element that allows us to breathe? 

Oxygen

200

What is an example of a Greenhouse gas? 

Carbon Dioxide 

Sulfur Dioxide

Ozone

CFC's 

Water Vapor 

200

This layer protects Earth from Meteoroids. Meteoroids usually burn up in this layer.

Mesosphere 

200

Top layer of Earth's surface that is suitable for plant growth and has rocks

Earth's Crust

200

The path an object follows as it moves around another object.

Orbit/Revolution/Elliptical Orbit

200

How does air pressure change as you get farther away from Earth? 

Closer to Earth (higher pressure) 

Farther away from Earth (less pressure) 

300

True or False: In New Orleans we will in low lying coastal areas that are at risk for increased flooding with Global Warming. 

True 

300

This layer starts off cold. However, the ozone warms up the upper region of the layer by absorbing the UV rays heat. 

Stratosphere

300

This part of Earth is mostly made of solid rock from the liquid outer core to the crust.

Mantle 

300

The spinning of Earth on its axis is called

Rotation
300

The two most abundant gases found throughout all of the layers are? 

Nitrogen and Oxygen

400
In the troposphere ozone is BAD. What makes the ozone bad? 

It is a pollutant 

400

This layer separates the rest of the atmosphere from outer space. 

Exosphere 

400

An object that is reduced to liquid form by heating.

Molten

400

There are two equinoxes every year. Which months do they occur in? 

September/Autumnal 

March/Vernal

400

Blocks harmful UV rays.

Ozone Layer 

500

The trapping of heat by gases in the atmosphere is called the ___________ Effect.

Greenhouse Effect

500
This layer is the hottest layer in the atmosphere. Though, you would be cold because there are not enough gas molecules to transfer heat to you. 

Thermosphere

500

The central portion of the Earth. Made mostly of iron/nickel.  

Core

500

It takes 365.25 days to complete one trip around the Sun. That extra quarter of a day presents a challenge to our calendar system, which counts one year as 365 days. To keep our yearly calendars consistent with our orbit around the Sun, every four years, we add one day. That day is called? 

Leap Year

How can the various gases stay in the atmosphere?

The attractive force of Gravity
