ixl what causes the seasons on earth

The model below shows Earth's orbit around the Sun. Select the image that shows how Earth's axis tilts at point A. Submit

In this image, Earth's axis is tilted in the same way as it is at point B.

Of the three models, this one shows the light striking Earth most directly, at close to 90°. So, in this region, the light is the most intense, and Earth's surface will heat up the most.

Match each cause with its effect. Earth's axis is tilted. Earth's surface is curved. cause effect When it is winter in the Northern Hemisphere, it is summer in the Southern Hemisphere. Locations near the North Pole and South Pole get less energy than locations near the equator.

When it is winter in the Northern Hemisphere, it is summer in the Southern Hemisphere. This happens because Earth's axis is tilted. As Earth orbits the Sun, the tilt of Earth's axis causes one hemisphere to receive more energy than the other. When the Northern Hemisphere is in winter, it receives the least energy and experiences the least heating of the whole year. At the same time, the Southern Hemisphere receives the most energy and experiences the most heating of the whole year, so it is in summer. Now, look at the second effect and think about what causes it: Locations near the North Pole and South Pole get less energy than locations near the equator. This happens because Earth's surface is curved. Sunlight strikes Earth most directly, or with the greatest intensity, near the equator. For locations farther away from the equator, the light spreads out over a larger area and strikes Earth with less intensity. Because the light is less intense, less energy reaches locations near the North Pole and South Pole. Got it

When sunlight reaches Earth's surface, the surface absorbs some of the energy and heats up. The more intense the sunlight is, the more energy there is to absorb. The three models below show the same amount of sunlight striking different parts of Earth's surface at different angles. Select the model that shows the part of Earth's surface that would heat up the least.

arth is tilted on its axis. Because Earth is tilted, different parts of Earth receive different amounts of energy from the Sun. As Earth orbits the Sun over the course of a year, there is a dramatic change in the amount of energy that each hemisphere receives. The model below shows Earth's orbit around the Sun. Earth is shown at a point when the Northern Hemisphere is in summer. Notice that at this point, the North Pole is tilted toward the Sun.

at this point in earths orbit

northern is in winter ... southern n the model, Earth is at a point in its orbit when one hemisphere is in summer and the other is in winter. The model shows that the light striking the Northern Hemisphere is less intense than the light striking the Southern Hemisphere. This tells you that the Northern Hemisphere is receiving less energy than the Southern Hemisphere. As a result, the Northern Hemisphere is being heated less than the Southern Hemisphere. So, at this point in Earth's orbit, the NorthernHemisphere is in winter, and the Southern Hemisphere is in summer.

The model below shows Earth at four points in its orbit around the Sun. The white lines at the North Pole and South Pole represent Earth's axis. Based on the model, which of the following is true? The tilt of Earth's axis stays the same throughout the year. Earth's axis is tilted during only half of its orbit. The North Pole always points toward the Sun. Submit

the tilt stays the same

You can see that the arrows striking Earth most directly, at close to 90°, do so in the Northern Hemisphere. So, at this point in Earth's orbit, the Northern Hemisphere is receiving more energy than the Southern Hemisphere. The hemisphere that receives more energy also experiences more heating. So, the Northern Hemisphere is heating up more than the Southern Hemisphere.

which hemisphere is receiving more energy, look for the hemisphere where light strikes Earth with the greatest intensity.
