Which of these is changed by the Milankovitch cycles ? (1 point) the duration of seasons on Earth the length of a year on Earth the amount of solar energy that reaches Earth the reflectivity of Earth

## Step 1<br />The Milankovitch cycles refer to the three cyclical changes in Earth's orbit and rotation that affect the amount of sunlight reaching Earth. These cycles are responsible for the timing of ice ages and the changing of seasons.<br /><br />## Step 2<br />The three cycles are:<br />1. Eccentricity: This refers to the shape of Earth's orbit around the Sun. The orbit is not perfectly circular but slightly elliptical.<br />2. Axial tilt: This is the angle between Earth's axis and the plane of its orbit around the Sun. This tilt is responsible for the changing seasons.<br />3. Precession: This is the wobble of Earth's axis over a period of 26,000 years.<br /><br />## Step 3<br />These cycles do not change the duration of seasons on Earth, the length of a year on Earth, or the reflectivity of Earth. Instead, they affect the amount of solar energy that reaches Earth.
