What main human activity caused Earth’s atmosphere to trap more heat?

Burning fossil fuels, Deforestation 

100

What is the main source of Earth’s energy?

The Sun.

100

What do greenhouse gases do with heat energy from the Sun?

They trap it, keeping Earth warm.

100

What does density measure?

How tightly packed matter is within an object

100

What is a molecule?

a group of 2 or more atoms bonded together

200

True or False — If more sunlight is REFLECTED BACK into space, Earth’s temperature goes up.

False — it would make Earth cooler.

200

If the Sun’s energy output increases, what happens to Earth’s temperature and why?

It rises because Earth receives more solar energy.

200

Can gases like nitrogen and oxygen absorb infrared heat energy? 

No

200

If two liquids don’t mix, which one will sink?

The one with higher density.

200

How many types of radiation exists? 

3

300

Explain why more greenhouse gases in the atmosphere cause global temperatures to rise.

They trap heat energy and prevent it from escaping into space.

300

What happens to radiation in Earth's atmosphere?

It is either reflected or absorbed.

300

Name the gases that make up greenhouse gases

Carbon Dioxide, Nitrous Oxide, Methane

300

Liquid A has a density of 1.8 g/mL, and Liquid B has 0.7 g/mL. Which one will float?

Liquid B

300

When looking at molecular motion, what affect does temperature have?

Higher temperature = faster motion 

Lower temperature = slower motion 

400

When looking at deforestation and volcanic eruptions, which is more likely to cause a decrease in temperatures?

Volcanic eruptions

400

If more energy is RELEASED from the atmosphere instead of being absorbed, what happens to temperatures?

They would decrease

400

When a greenhouse gas releases heat energy, where can it go?

Earth’s surface, or out into space.

400

What is the mathematical equation to solve for density?

Density = mass/volume

400

Name the three types of radiation.

Visible Light, Ultraviolet, Infrared
500

If the energy that enters Earth's atmosphere is the same amount of energy that is already existing, what happens to the global temperature? 

It would remain the same.

500

How do changes in Earth’s orbit or tilt affect how much sunlight reaches the planet?

They change the amount and angle of sunlight, affecting seasons and climate.

500

Which TWO would MOST LIKELY cause an increase of temperature? 

1. Changes in Earth's Tilt 

2. Increased levels of greenhouse gases 

3. Solar output 

4. Volcanic Eruptions

Increased levels of greenhouse gases, solar output

500

What is the density of water?

1g/mL

500

During the Ice Age, the Earth was covered in ice which means there was less absorption of radiation in the atmosphere. Describe what that would mean for atmospheric temperatures?

It would be colder because heat from the radiation would not stay.
