Earth is in constant motion. It rotates once every 24 hours, which causes day and night. Earth also orbits the Sun once every year. During Earth's orbit, different parts of Earth experience different seasons. For example, the model below shows Earth at a point in its orbit when it is winter in the Northern Hemisphere and summer in the Southern Hemisphere. north pole south pole northern hemisphere southern hemisphere and equator

Question

Label the model.

(1 point)

Answer 1

To label the model, you can use the following labels:

1. North Pole: This is the northernmost point on Earth.
2. Northern Hemisphere: The half of the Earth that is north of the equator.
3. Equator: The imaginary line that divides the Earth into the Northern and Southern Hemispheres.
4. Southern Hemisphere: The half of the Earth that is south of the equator.
5. South Pole: This is the southernmost point on Earth.
6. Sun: Indicate where the Sun is located in relation to the Earth, showing that sunlight is primarily reaching the Southern Hemisphere during this time.

Make sure the placement of these labels reflects the positions as they relate to the model you're working with. Depending on the orientation of your diagram, you might also want to indicate the direction of Earth's rotation, which is counterclockwise when viewed from above the North Pole.

Answer 3

To determine which model shows the part of Earth's surface that would heat up the least, you need to look for the model where sunlight is striking at the most oblique angle.

Sunlight that strikes the Earth's surface at a steeper angle is more concentrated and therefore heats that area more effectively. Conversely, sunlight striking at a shallower angle spreads out over a larger area and thus provides less heat.

1. Model A: If the sunlight is hitting directly (at a 90-degree angle), it would heat up the most.
2. Model B: If the sunlight is at an intermediate angle, the heating would be moderate.
3. Model C: If the sunlight is hitting at a very oblique angle, this area would heat up the least.

Based on this reasoning, the model that shows the part of Earth's surface that would heat up the least is Model C.

The model below shows the Moon at one position in its orbit around Earth. The white half of the Moon represents the part of the Moon that is lit up by the Sun. Select the phase of the Moon shown in the model.

Answer 5

To determine the phase of the Moon shown in the model, we need to consider how the Moon appears based on its position in relation to the Earth and the Sun.

1. Full Moon: The entire face of the Moon is illuminated, meaning the Earth is between the Sun and the Moon.
2. Third Quarter Moon: Half of the Moon is illuminated on the left side when viewed from the Northern Hemisphere.
3. New Moon: The Moon is between the Earth and the Sun, and the side facing the Earth is not illuminated; it appears dark.
4. 1st Quarter Moon: Half of the Moon is illuminated on the right side when viewed from the Northern Hemisphere.

If the model shows the Moon with the white half lit up, and especially if it appears that either the left or right side is illuminated, we can identify the specific phase:

• If it shows the right side of the Moon lit up, it would be a 1st Quarter Moon.
• If the left side is lit up, it would be a Third Quarter Moon.

Since I don't have access to the model you are referencing, I recommend checking which side of the Moon is illuminated:

• If the illuminated part is on the right side, select 1st Quarter Moon.
• If the illuminated part is on the left side, select Third Quarter Moon.
• If it shows no illumination at all, select New Moon.
• If the entire face is lit, select Full Moon.

Choose the response based on that information.

Answer 6

the sunlight is faceing forward

Answer 7

If the sunlight is facing directly towards the Moon and the illuminated side is fully visible, this indicates that the Moon is in the Full Moon phase.

In this case:

• The entire face of the Moon is lit up because it is opposite the Sun, meaning Earth is between the Moon and the Sun.

Therefore, the correct selection would be Full Moon.

Answer 9

The two factors that determine the strength of gravitational force between two objects are Mass and Distance.

• Mass: The greater the mass of the objects, the stronger the gravitational force between them.
• Distance: The greater the distance between the centers of the two objects, the weaker the gravitational force.

So, the correct response is Mass and Distance.

Answer 11

To order astronomical bodies from smallest to largest, here’s a typical hierarchical structure you can follow:

1. Moon (or satellite) - a natural satellite that orbits a planet.
2. Planet - a celestial body that orbits a star and is large enough to be rounded by its own gravity.
3. Star - a massive celestial body composed of plasma that generates energy through nuclear fusion.
4. Galaxy - a vast system of stars, stellar remnants, gas, dust, and dark matter, bound together by gravity.
5. Universe - the largest scale, encompassing all galaxies, stars, planets, and all matter and energy.

So, the correct order from smallest to largest is:

1. Moon (or satellite)
2. Planet
3. Star
4. Galaxy
5. Universe

Feel free to adapt this list if specific responses are provided, but in general, this order reflects the typical size hierarchy in astronomy.
