How Ice Ages Happen

What is primarily responsible for the changes in Earth's climate according to the Milankovitch theory?

• Volcanic activity

• Ocean currents

• Sunlight variations in northern latitudes

• Atmospheric composition changes

Why is ice significant in climate change?

• It increases Earth's gravitational pull

• It emits greenhouse gases

• It reflects sunlight, cooling the Earth

• It absorbs a lot of heat

What causes the Earth's tilt to change over time?

• Solar flares

• Magnetic field shifts

• Gravitational pull from the moon

• Gravitational influences from other celestial bodies

How does the Earth's orbit shape affect its climate?

• A more elliptical orbit has no effect on climate

• A more circular orbit leads to milder seasons

• A more elliptical orbit causes more extreme weather

• A more circular orbit increases global temperatures
