Middle school is still hard.

QuestionAnswer
Albedo A measure how much sunlight is reflected away from a surface.
Atmosphere The mixture of gases surrounding a planet.
Carbon Dioxide A gas found in the atmosphere that comes from combustion and reflects energy.
Climate General weather patterns over a long period of time.
Climate Change Changes in climate over large period of time that can be caused by natural or human activities.
Combustion The process of burning fuels that produces carbon dioxide.
Convergent Moving toward the same place.
Cross Section A diagram that shows what the inside of something looks like.
Deforestation The process of clearing trees from land.
Divergent Moving apart in different directions.
Earthquake A sudden shaking of Earth's surface.
Energy The ability to make things move or change.
Eruption The sudden pushing out of something, such as lava from a volcano.
Fluctuation Variations in a set of data.
Fossil Evidence of life from the past, such as fossilized bones, footprints, or leaf prints.
Human Activities Things people do that affect the Earth system.
Lux A measure of how much light is present.
Mantle The layer of soft, solid rock underneath Earth's plates.
Mesosaurus An extinct reptile that lived about 300 million years ago.
Methane A gas found in the atmosphere that comes from cows and trash that also keeps energy in.
Outer Layer Earth’s outermost layer of hard, solid rock that is underneath the soil, vegetation, and water.
Pattern Something we observe to be similar over and over again.
Plate One of the very large sections of hard, solid rock that make up Earth’s outer layer.
Reflect To bounce off without absorbing.
Stability When something stays the same over time.
Sulfur Dioxide A gas found in the atmosphere that comes from volcanoes.
Temperature A measure of how hot or cold something is; the higher the temperature is, the more energy it has.
The Earth System The living and nonliving components of the Earth, including the water, land and atmosphere.
Trend Overall tendency (for example, a consistent increase) in a set of data over time.
Volcano A mountain that has an opening in the land where gas, lava, and/or ash is pushed out.
What are the effects of increasing CO2 in the Earth System? Increased CO2 causes more energy to be kept in by reflecting escaping energy in the atmosphere back down to Earth. This increases both temperature and energy in the Earth System.
How has the invention of the combustion engine affected Earth's energy and average temperature? The invention of the combustion engine affected Earth's energy and climate becausecombustion is burning fossil fuels, which produces CO2.
How did fossils of the same animal get so far apart, (on different continents) and how long would it take? Fossils of the same animal were together once on a super continent, but moving plates split them up. It takes millions of years because plates move a few centimeters a year.
What were the 3 criteria to the ECC (Earth's Changing Climate) internship, and why are each important? The 3 criteria of the internship are reduce climate impact (producing less CO2), preserve historic value (which is how Solton gets money), and keep costs low (so they can afford other things for the city.)
