Earth's Position and Solar Radiation Flashcard

Front

Which orbital cycle is responsible for changes in Earth's tilt? Options: Eccentricity, Precession, Obliquity, Rotation

Back

Obliquity

Front

What is Earth's eccentricity?

Back

The shape of Earth's orbit around the Sun

Front

How has the amount of solar radiation reaching Earth at 65° N varied over the last 750,000 years?

Back

It has fluctuated over time.

Front

Which of the following best describes the Milankovitch Cycles?

Back

They are the cycles of Earth's orbital shape, tilt, and wobble.

Front

What is the primary factor that causes variations in the amount of solar radiation reaching Earth?

Back

Changes in Earth's distance and tilt relative to the Sun.

Front

How does Earth's eccentricity (shape of orbit) affect the amount of solar radiation it receives?

Back

It changes the distance between Earth and the Sun.

Front

What evidence supports the causal (cause and effect) relationship between Milankovitch Cycles and glacial-interglacial cycles?

Back

Ice core data showing patterns of temperature change.

Front

What is a result of Earth's precession (wobble)?

Back

Changes in the timing and length of seasons.

Front

How do changes in Earth's tilt affect climate?

Back

They alter the distribution of sunlight across Earth's surface.

Front

What role do Milankovitch Cycles play in climate change?

Back

They contribute to natural climate variability.
