Which variable of the Milankovitch Cycles is most responsible for the different seasons on Earth?

• eccentricity (the shape of Earth's orbit)

• obliquity (the tilt of Earth's axis)

• precession (the wobble of Earth's axis)

the Milankovitch cycle of Eccentricity is when...

• the shape of Earth's orbit changes in the amount of how round or oval it is.

• The tilt of Earth's orbit changes from 22.5 to 24.5 degrees

• the wobble of Earth on it's axis changes positions.

• the Earth's volcanoes all erupt at once.

Which of the following best describes the tilt of the earth during the spring and fall equinoxes?

• The earth is tilted away from the sun (Northern hemisphere)

• The earth is tilted neither toward or away from the sun (tilt is side to side)

• The earth is tilted toward the sun (Northern hemisphere)

• The earth is not tilted during spring and fall

• As the light became indirect, the temperature would stay the same.

• As the light became indirect, the temperature would increase.

• As the light became indirect the temperature would decrease.

The angle at which the Sun’s rays hit Earth’s surface and the relative areas of Earth’s surface receiving the rays at the three different angles of insolation are shown. As viewed in sequence from A to B to C, these diagrams represent which months and which change in the intensity of insolation?

• December → March → June; and decreasing intensity

• December → March → June; and increasing intensity

• June → September → December; and decreasing intensity

• June → September → December; and increasing intensity

The reason we have seasons on our planet is because...

• we are closer to the sun during the winter and further during the winter.

• the tilt of Earth's axis allows for more direct sunlight in the summer and less direct sunlight in the winter.

• seasonal wind patterns carry warmer winds during the summer and colder winds during the winter.

• the Earth's orbit becomes more like an oval to give us different seasons.
