Changing Climate Flashcards
1
Q
Milankovitch Cycles
A
eccentricity
obliquity
precession
2
Q
Eccentricity
A
changes in the shape of Earths orbit
3
Q
Precession
A
the amount Earth wobbles on its axis
3
Q
Obliquity
A
changes in how Earth tilts on its axis
4
Q
How milankovitch cycles affects Earths climate
A
Earth’s orbit means Earth is furthest from the sun during Northern hemisphere summers
Earth has less tilt
Earth’s wobble means the Northern hemisphere has cooler and shorter summers
5
Q
Sun Spots
A
dark spots on the Earths surface
temporary
caused by magnetic storms
increases the amount of energy Earth receives from the sun
causes it to warm up
6
Q
Volcanic Activity
A
when volcanoes erupt they release huge amounts of dust into the atmosphere
this dust blocks sunlight
which means cooler temperatures on Earth
