Earth is a system because
represent separate closed systems
it supports life

Humans releasing carbon dioxide into the atmosphere is an interaction of...
carbon with the atmosphere
carbon with the hydrosphere
How does carbon enter the atmosphere?
Photosynthesis
phytoplankton
Burning fossil fuels
What is the ozone layer function?
Protect against layers of rock
Protect against carbon dioxide
It helps us breath
Protect against sun UV rays
How does carbon interact with the atmosphere?
Organisms eat it
It is released into the atmosphere by burning fossil fuels
It is stored in rocks
It is dissolved in the ocean
How does carbon interact with the geosphere?
It is stored in rocks
It forms in the water
It is released by burning contaminants
It is part of all living organisms
Earth is considered a system because....
It is an open system
Every sphere is interacting with each other all the time
It is a place where each sphere works independently
It uses the sun as a source of energy
What is plankton?
It's the one that converts carbon dioxide in methane
Releases sulfur when exhaled into the air
Microorganisms that absorb (take away) carbon dioxide from the atmosphere
It is the source of energy of our planet
Which of the following is a fossil fuel?
Petroleum which is a form of carbon
Ozone
Radioactive Uranium
Wood from trees
What is the source of Petroleum and natural gas?
Plant and animal remains buried deep in the ocean from millions of years ago
From burning of plants and forests
Plants that have been collected from swamps
plants and animals that have become radioactive
What is one of the inconveniences of solar energy?
Houses look very ugly with those panels on the roof
It can't convert solar energy in electric energy
The panels and installation is very expensive
It is a type of energy that produces pollution to the environment
How does a dam produce energy?
Using wind a source of energy
Using the sun as a source of energy
Using ocean tides as a source of energy
Using water as a source of energy
Why does burning fossil fuels changes affect the greenhouse effect?
Because it releases carbon that has been trapped for millions of years under the layers of rock into the atmosphere. This carbon dioxide in atmosphere blocks solar energy to leave the earth and makes the earth become warmer than what it should
Because it releases carbon that has been trapped in the atmosphere into the layers of the rock. This allows solar energy to leave the system and makes temperatures decrees.
From the following, which is a consequence not caused by humans?
Droughts
Animal extinctions
Glacier formation
Forest destruction
Which one the geometric energy?
Water that comes down in the form of snow
water that comes down in the form of rain
water from the ocean
very hot water that comes from underground volcanic zones
Example of a renewable resource
Petroleum / fossil fuel
Cotton used to make clothes
What is a renewable resource?
It is a resource that can be used infinite times and never ends
It is a resource that will end one day. It would take millions of years to be formed again.
Having some carbon dioxide in the atmosphere is good because
It makes more rain
It keeps the temperature warm on the earth's surface
It deflects space radiation
It provides protection against meteorites
Rocks are classified by
Color
Size
how they are formed
The hardest, most common mineral is
Quartz
Diamond
Granite
Talc
large crystals are formed by
slow cooling of magma
fast cooling of magma
The term intrusive rocks means:
Formed inside (underground)
Formed outside (exterior)
Metamorphic rock is formed through
Heat and pressure
Melting and crystallization
The lines in a metamorphic rock are called
Just lines
Ripples
Foliation
When ice freezes it expands:
10%
100%
20%
200%
What place on earth should have more mechanical weathering?
A very cold place
A very hot place
In Illinois soil is considered transported because
It came from the north to the south
It came from the east to the west
Gravity causes:
Things to stay in place
Mass movement
Weather patterns
Wind to move
The movement from point A to point B is called
Erosion
Weathering
