Natural Climate Change Flashcards
What natural events can change our climate?
Asteroid collisions Volcanic eruptions Solar output Changes in the Earth’s orbit
How can the Earth’s orbit change our climate?
Sometimes we are closer to the sun. Earth gets warmer. Sometimes we are further away from the sun. Earth gets cooler
How can solar output (sun spots) change our climate?
Sometimes the sun has more sun spots. More heat leaves the sun (solar output). Earth gets warmer. Less sun spots (less solar output) Earth gets cooler.
How can volcanic eruptions change our climate?
Volcano erupts. Ash is thrown up into the atmosphere. It blocks out the sun. Earth gets cooler.
How can asteroid collision change our climate?
Asteroid hits Earth. Dust, rock and mud are thrown up into the atmosphere. It blocks out the sun. Earth gets cooler.
