its role is to dilute oxygen to the appropriate level

Volcanoes are made of what kind of rocks?
igneous rocks
What is water that is safe to drink called?

planets that are similar to the earth in density and size
What is ozone composed of?
oxygen atoms
What is a fault?
A crack in rock where movement has occurred
An enlarged depression caused by an explosion or the collapse of a volcanic cone
What is happening to sea levels globally?
they are rising
How was the atmosphere formed?
By a direct act of God during the Creation week
What is the difference between Ionosphere and magnetosphere?
Ionosphere- atmospheric layer directly affects radio communications on Earth
Magnetospherere-layer that would be most effective in protecting the earth from a solar flare
What is the name for a geologist who studies the earth's movements and structure of its interior?
seismologist
What is geothermal energy?
The internal energy of the earth, particularly evident in areas where hot springs and geysers exist.

What is retrograde motion?
When a planet appears to stop and then move backward against the stars in the background.
What is the difference between conduction and convection?
Convection- the density currents that cause a mixing of the air
Explain how the terms magnitude and intensity relate to an earthquake and its effect on people.
Magnitude is how strong it is measured to be .
Intensity is how much damage it causes.
What are the 3 types of volcanoes and the characteristics of each?
Shield- emits mostly lava in quiet eruptions
Stratovolcano- emits lava and solid debris in alternately quiet and explosive eruptions
Cinder cone- emits mostly cinders, ashes, and bombs.
Extinct volcano- a volcano that has no historical record of eruption and shows no seismic indications of activity.
Give at least 3 ways our lives are dependent on the existence of oceans.
By absorbing the sun's heat, oceans affect the weather and support a livable climate.
The abundant plant and animal life provide food.
Most of our oxygen comes from ocean life.
Fresh water can also be obtained from the oceans though desalination.
And, for transportation.
Name the planets in order from closest to farthest from the sun.
Mercury, Venus, Earth, Mars, Jupiter, Saturn, Uranus, Neptune
How does the atmosphere give evidence for divine design?
God has created the atmosphere to provide a proper ratio of gases for all living things for breathing and for protection from harmful rays and particles from space. The ozone layer, for instance, blocks much of the sun's ultraviolet radiation that can cause health complications for humans and other living things.
