Evidence of Climate Change

QuestionAnswer
carbon cycle he continuous, natural process by which carbon atoms travel between the atmosphere, Earth’s surface (land/oceans), and living organisms.
carbon emissions release of carbon-based gases—most commonly carbon dioxide and methane—into the atmosphere.
greenhouse gases gases in Earth’s atmosphere—such as carbon dioxide, methane, and water vapor—that trap heat from the sun near the surface, acting like a blanket to keep the planet warm.
greenhouse effect a natural process where atmospheric gases (like and methane) trap heat radiating from Earth’s surface, preventing it from escaping into space and keeping the planet habitable
fossil fuels non-renewable energy sources—specifically coal, petroleum (oil), and natural gas—formed from the buried remains of ancient plants and animals subjected to intense heat and pressure over millions of years
global warming the long-term rise in Earth's average temperature, primarily caused by increased greenhouse gases (like and methane) from human activities such as burning fossil fuels and deforestation.
aerosols tiny solid particles or liquid droplets suspended in a gas, usually air
natural causes of climate change volcanic eruptions, meteor impact, greenhouse gases, global ocean currents
human activities that causes climate change greenhouse gases, deforestation, urbanization
deforestation the large-scale, permanent removal of trees and forests by humans to make room for other uses, such as farming, cattle ranching, or building infrastructure
urbanization the process where more and more people move from rural areas (countryside) to cities, causing cities to grow in size and population
atmosphere a thin, protective layer of gases (mostly nitrogen and oxygen) surrounding Earth, held in place by gravity
carbon is a nonmetal chemical element (symbol C, atomic number 6) essential to life, forming the basis of organic chemistry and all living organisms
renewable energy energy derived from natural, virtually inexhaustible sources that replenish themselves faster than they are consumed.
ocean currents Ocean currents are continuous, directed movements of seawater, acting like vast rivers flowing in predictable patterns across the ocean surface or in deep water
acid rain any form of precipitation—rain, snow, fog, or dust—with high levels of nitric and sulfuric acids, usually having a pH below 4.5. It is primarily caused by human activities like burning fossil fuels

Use these flashcards to help memorize information. Look at the large card and try to recall what is on the other side. Then click the card to flip it. If you knew the answer, click the green Know box. Otherwise, click the red Don't know box.

When you've placed seven or more cards in the Don't know box, click "retry" to try those cards again.

If you've accidentally put the card in the wrong box, just click on the card to take it out of the box.

You can also use your keyboard to move the cards as follows:

If you are logged in to your account, this website will remember which cards you know and don't know so that they are in the same box the next time you log in.

When you need a break, try one of the other activities listed below the flashcards like Matching, Snowman, or Hungry Bug. Although it may feel like you're playing a game, your brain is still making more connections with the information to help you out.
