What is the Carbon Cycle?
The Carbon Cycle is the process by which carbon is exchanged among the atmosphere, land, water, and living organisms.
What is Combustion?
Combustion is a rapid chemical reaction when a substance reacts with oxygen, resulting in heat and light.
What are Fossil Fuels?
Fossil fuels are naturally occurring energy sources formed from fossilized remains of plants, organisms, and animals over millions of years.
What is Chemical Energy?
Chemical Energy is the potential energy stored in chemical bonds between molecules and atoms.
What is Photosynthesis?
Photosynthesis is the process of plants using energy from the sun to turn it into chemical energy stored in the form of sugar.
What is Decomposition?
Decomposition is the natural process of dead plants, animals, and organisms breaking down into simpler substances.
What is Diffusion?
Diffusion is the movement of particles from a region of higher concentration to a region of lower concentration.
What are Carbonate Rocks?
Carbonate rocks are sedimentary rocks made of carbonate minerals, such as calcite and dolomite.
What is Respiration?
Respiration is the process of organisms exchanging gases with their environment, taking in oxygen and releasing carbon dioxide to produce energy.
What causes the seasons?
The cause of the seasons is because of the Earth’s axial tilt of 23.5 degrees when it orbits around the sun.
What is direct sunlight?
Direct sunlight is sunlight that reaches a surface directly from the sun. It is the most intense form of sunlight.
What is indirect sunlight?
Indirect sunlight is sunlight that is diffused or scattered before it reaches a surface on Earth.
What are the hours of daylight during the summer solstice in Antarctica?
During the summer solstice in Antarctica, there is 24 hours of sunlight for 6 months.
What are the hours of daylight during the winter solstice in Antarctica?
During the winter solstice in Antarctica, there is 0 hours of sunlight for 6 months.
What are the expected hours of sunlight in CT during summer?
In the summer, in CT, there is an expected 12 hours of sunlight per day.
What are the expected hours of sunlight during the summer solstice in CT?
During the summer solstice in CT, there is an expected 14-15 hours of sunlight.
What are the expected hours of sunlight during the winter solstice in CT?
During the winter solstice in CT, there is an expected 9 hours of sunlight.
What is the tilt of the Earth’s axis?
The tilt of the axis is 23.5 degrees. This tilt is responsible for the change of seasons on Earth.
What is the major axis of an ellipse?
The major axis of an ellipse is the longest diameter of the ellipse, passing through the center and both foci.
What is eccentricity in relation to an ellipse?
The eccentricity of an ellipse is a value between 0 and 1 that describes how close an ellipse is to being a circle.
What is perihelion?
The perihelion of an ellipse is the point where the orbiting body is closest to the central body in its elliptical path.
What is aphelion?
The aphelion of an ellipse is the point on the elliptical orbit where the orbiting object is farthest from the central body (opposite of perihelion).
What is ozone?
Ozone (O3) blocks 98% of the sun’s harmful UV rays and turns it into heat. It is found in the stratosphere.
What are chlorofluorocarbons (CFCs)?
Chlorofluorocarbons are a group of chemical compounds containing carbon, chlorine, and fluorine. They have been linked to ozone depletion.
