affects the atmosphere

What is “Animals breath in oxygen and

release carbon dioxide.”?

all 4 spheres.

Original answer

Animals in “_______ ___ communities” do not rely

on sunlight for their energy. Instead they use heat energy from Earth’s

interior.

What are hydrothermal vent

communities?

Which of Earth’s energy sources

provides the least amount of Earth’s

energy budget?

What is tidal?

Ocean waves are powered by this energy source.

What is solar?

These 3 factors create Earth’s

tides.

What is gravity of the sun, gravity of

the moon, and Earth’s rotation?

Identify 3 types of energy present in burning alcohol.

What are light, heat, and chemical potential energy?

gasoline powered car back to the sun.

Car Moving (K) Gas (CP) dead animals (CP) plants (CP) Sun (EM)

Earth’s equator has a

circumference of about…

What is 25,000 mi (40,000 km)?

Give an example of something with

high albedo.

What is snow?

It would take about this many hours to fly

around Earth in a standard commercial

airline.

List 3 matters & 4 energies in a talking student. Explain the

energies.

Matter – head, arms, feet

Energy – sound (talking)

heat (they’re warm)

Kinetic (mouth is moving)

chem. poten. (could be eaten or burned)

Infrared (radiating heat)

This source of energy powers tsunamis.

What is geothermal?

This source of energy powers

waves.

What is solar?

These are the two reasons Earth is

hot inside.

What are radioactive isotopes decaying and

heat leftover from formation?

the energies.

Matter – pages, cover

Energy –

Gravitational poten. (can fall)

chem. poten. (could be eaten or burned)

heat (It’s not at absolute zero.)

Infrared (radiating heat)

Make your wager

Explain why the sun shines.

1.Give the name of the process

2.identify where it happens

3.the conditions that cause it to happen

4.identify what’s turning into what

5.how long it takes energy get to the surface

6.how long it takes to get to Earth

The sun shines because of a process called nuclear fusion. Extreme heat & pressure in center of sun pushes hydrogen atoms together. The hydrogen atoms combine to form helium atoms & energy. After a million years or so, the energy reaches the surface of the sun

From there, it takes about 8 minutes to reach Earth’s surface.
