Summary
100
The amount of matter in a certain amount of space.
What is density?
100
Gases; blocks harmful radiation.
What is the atmosphere?
100
The transfer of energy from one object to another.
What is heat?
100
Sources: Atmosphere 1. Living organisms breathing. 2. Fossil fuels. 3. Volcanic eruptions.
What is the carbon cycle?
100
This type of change includes the following clues: 1. Color change. 2. Change of temperature (hotter or colder). 3. Bubbles (gas production). 4. PH change (more or less acidic).
What is a chemical change?
200
A change of matter that does not change its identity or composition.
What is a physical change?
200
Solids; includes crust (and ocean floors) and the mantle.
What is the geosphere?
200
The measure of the average kinetic energy of the particles in a substance.
What is temperature?
200
Critical part of proteins and enzymes which creates DNA/RNA.
What is the nitrogen cycle?
200
This Earth system is always changing: tectonic plates and weather. Mineral resources are mined from the crust.
What is the geosphere?
300
The process where matter chemically changes into something completely new or different.
What is a chemical change?
300
H20; includes liquid and frozen forms.
What is the hydrosphere?
300
Example: Boiling water = 212 degrees Fahrenheit.
What is temperature?
300
Plant and animal life would not exist without it. Used for respiration and critical component of water.
What is the oxygen cycle?
300
This Earth system gives initiation that we are the only known life in the Solar System (that we know of). It impacts other systems more than any other.
What is the biosphere?
400
A kind of model; includes time as a variable, and often cannot be controlled.
What is a system?
400
Living organisms; single-celled to multiple celled.
What is the biosphere?
400
Example: Cold water receives energy from hand and air when holding a water bottle.
What is low energy?
400
Sinks: Geosphere - limestone formation. Atmosphere - plants; photosynthesis. Hydrosphere - diffuses into the ocean. Plankton, photosynthesis.
What is the carbon cycle?
400
This cycle has to change forms constantly. There is 78% of it in the atmosphere, but it is not usable. It enters: 1. Atmosphere - lightning and humans-industry. 2. Geosphere - bacteria "fix" it, animal excrement, and humans (fertilizer).
What is the nitrogen cycle?
500
Energy can enter, but matter does not leave nor enter.
What is a closed system?
500
A sequence of events that repeats over periods of time; may be short or long periods.
What is a cycle?
500
Example: Boiling water transfer energy to air and container.
What is high energy?
500
Plants use this to make chlorophyll for photosynthesis and growth. Without it, plants would not survive.
What is the nitrogen cycle?
500
Possible causes/creations of this place are the following: 1. Too much nitrogen being released into the ocean. 2. the death of large amounts of phytoplankton. 3. Wind/ocean currents bring oxygen-poor water up from deep water. 4. Climate change.
What is the Ocean Dead Zone.
