B4L2 Milankovitch Cycles review

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 eccentricity in the context of Milankovitch Cycles?

Back

Eccentricity refers to the shape of Earth's orbit around the Sun, which can vary from more circular to more elliptical over a cycle of about 100,000 years.

Front

What is obliquity?

Back

Obliquity is the angle of tilt of Earth's axis relative to its orbital plane, which varies between 22.1 and 24.5 degrees over a cycle of about 40,000 years.

Front

What is precession?

Back

Precession is the gradual wobble of Earth's axis, which affects the orientation of the axis and occurs over a cycle of about 26,000 years.

Front

How does obliquity affect seasons?

Back

Obliquity affects the intensity of seasons; a greater tilt results in more extreme seasons, while a smaller tilt leads to milder seasons.

Front

What is the significance of Milutin Milankovitch?

Back

Milutin Milankovitch was a Serbian mathematician and astronomer who developed the theory that Earth's orbital changes influence climate patterns.

Front

What is the period of Earth's obliquity?

Back

The period of Earth's obliquity is approximately 40,000 years.

Front

What is the period of Earth's precession?

Back

The period of Earth's precession is approximately 26,000 years.

Front

How does eccentricity influence climate?

Back

Eccentricity influences climate by changing the distance between Earth and the Sun, affecting the amount of solar energy received.

Front

What role do Milankovitch Cycles play in ice ages?

Back

Milankovitch Cycles are believed to be a key factor in the timing of ice ages, as they influence the distribution of solar energy on Earth.
