Question

Which of these is changed by the malikovich cycles
The length of a year on Earth
The reflectivity of Earth
The amount of solar energy that reaches Earth
The duration of seasons on Earth

Answer 1

The Milankovitch cycles primarily affect the **amount of solar energy that reaches Earth**. These cycles involve variations in Earth's orbit, axial tilt, and precession, which influence how sunlight is distributed across the planet over long periods. This alteration in solar energy can lead to changes in climate patterns, including the intensity and duration of seasons, but the cycles themselves do not change the length of a year or Earth's reflectivity.
