Milankovitch Cycles/Natural Climate Change

Front

What are Milankovitch Cycles?

Back

Milankovitch Cycles are long-term variations in Earth's orbit and axial tilt that affect climate patterns over thousands of years.

Front

What is the role of greenhouse gases in Earth's climate system?

Back

Greenhouse gases help prevent the Earth from cooling substantially at night and trap heat in the atmosphere, maintaining a moderate temperature.

Front

What is the angle of the Earth's axis called?

Back

The angle of the Earth's axis is called 'Tilt'.

Front

Where are the sun's rays least direct?

Back

The sun's rays are least direct near the poles.

Front

What is the difference between weather and climate?

Back

Weather refers to short-term atmospheric conditions, while climate is the average of these conditions over long periods.

Front

What shape does Earth's orbit take during Milankovitch Cycles?

Back

Earth's orbit changes from more circular to oval-shaped.

Front

What is precession in the context of Milankovitch Cycles?

Back

Precession is the gradual shift in the orientation of Earth's axis, affecting climate over long periods.

Front

What is orbital eccentricity?

Back

Orbital eccentricity refers to the shape of Earth's orbit around the sun, which can vary from circular to more elongated.

Front

How does axial tilt affect seasons?

Back

Axial tilt causes variations in sunlight distribution, leading to the changing seasons as Earth orbits the sun.

Front

What is the significance of the greenhouse effect?

Back

The greenhouse effect is crucial for maintaining Earth's temperature, allowing life to thrive by trapping heat.
