3. A cycle of Moon phases can be seen from Earth because the(Standard 1.1b)?

Moon’s distance from the Earth changes at a predictable rate

Moon’s axis is tilted

Moon spins on its axis

Moon revolves around the Earth

Moon rotates in a clockwise direction

The cycle of Moon phases can be seen from Earth because the Moon revolves around the Earth. As the Moon orbits around the Earth, different portions of its illuminated side become visible to us on Earth, resulting in the different phases of the Moon that we observe. The Moon's revolution around the Earth causes this cyclical pattern of phases that we can see from Earth.

4. The apparent rising and setting of the sun, as viewed from Earth, is caused by (Standard 1.1d):

The Sun’s rotation

The Sun’s revolution

Earth’s rotation

Earth’s revolution

The Moon’s revolution and rotation

The apparent rising and setting of the sun is caused by Earth's rotation. As the Earth rotates on its axis, different parts of the planet are exposed to the sun's light, creating the illusion of the sun moving across the sky. This rotation gives us day and night, as well as the changing positions of the sun throughout the day. The other options, such as the Sun's rotation or revolution, or the Moon's revolution and rotation, do not directly affect the rising and setting of the sun as viewed from Earth.

5. What characteristic(s) are used to classify stars (Standard 1.1a)?

Temperature

Luminosity

Size

Temperature and size

Temperature, size and luminosity

Stars are classified based on their temperature, size, and luminosity. Temperature is an important characteristic as it determines the color of a star and provides information about its surface temperature. Size refers to the physical dimensions of a star, which can vary from small to large. Luminosity is the total amount of energy radiated by a star per unit time and is related to its brightness. By considering these three characteristics, scientists can categorize stars into different types and understand their properties and evolutionary stages.

6. When is the force of gravity between two objects in the solar system the greatest (Standard 1.1a)?

Masses are large and objects are close together.

Masses are large and objects are far apart.

Masses are small and objects are close together.

Masses are small and objects are far apart.

Size and distance do not affect gravity.

When the masses of two objects in the solar system are large and they are close together, the force of gravity between them is the greatest. This is because the force of gravity is directly proportional to the product of the masses of the objects and inversely proportional to the square of the distance between them, according to Newton's law of universal gravitation. Therefore, when the masses are large and the objects are close together, the force of gravity between them is maximized.

7. Base your answer to this question on the diagram below, which shows the tilt of the Earth on its axis in relation to the sun on one particular day. Points A through E are locations on Earth's surface. Point D is located in New York State. The dashed line represents Earth's axis. Why is New York experiencing winter on this day (Standard 1.1f)?

The Earth is at the farthest point from the sun in its orbit.

The Earth is at the closest point to the sun in its orbit.

The Northern Hemisphere is tilted towards the sun.

The Southern Hemisphere is tilted towards the sun.

New York is not experiencing winter.

8. The diagram below illustrates three stages of a current theory of the formation of the universe. A major piece of scientific evidence supporting this theory is the fact that wavelengths of light from galaxies moving away from Earth are observed to be (Standard 1.2a):

Normal by exhibiting no shift at all

Longer than normal by exhibiting a red-shift

Longer than normal by exhibiting a blue-shift

Shorter than normal by exhibiting a red-shift

Shorter than normal by exhibiting a blue-shift

The fact that wavelengths of light from galaxies moving away from Earth are observed to be longer than normal by exhibiting a red-shift supports the theory of the formation of the universe. This is because the red-shift indicates that the galaxies are moving away from us, which is consistent with the idea that the universe is expanding. The longer wavelengths of light suggest that the galaxies are moving away from us at a high velocity, supporting the theory of the Big Bang and the expansion of the universe.

9. Which statement provides evidence that the Earth revolves around the Sun (Standard 1.1g)?

The Earth’s axis is tilted 23.5°.

Winds at different latitudes are curved different amounts by the Coriolis effect.

The Sun follows an apparent arc across the sky during the day.

The stars appear to circle the Earth during the night.

Different star constellations are visible from Earth at different seasons of the year.

The statement "Different star constellations are visible from Earth at different seasons of the year" provides evidence that the Earth revolves around the Sun. This is because as the Earth orbits the Sun, our perspective of the night sky changes. Different star constellations become visible at different times of the year as we move to different positions in our orbit around the Sun. This phenomenon is known as stellar parallax and is a direct result of the Earth's revolution around the Sun.

10. Which statement best describes the structure and location of the Sun (Standard 1.1b)?

The Sun converts mass into energy by nuclear fusion and is located in the Milky Way galaxy.

The Sun converts mass into energy by heat transfer and is located in the Milky Way galaxy.

The Sun converts mass into energy by radioactive decay and is located in the Milky Way galaxy.

The Sun converts mass into energy by nuclear fusion and is located in the Andromeda galaxy.

The Sun converts mass into energy by radioactive decay and is located in the Andromeda galaxy.

The correct answer is that the Sun converts mass into energy by nuclear fusion and is located in the Milky Way galaxy. This is because nuclear fusion is the process by which the Sun produces energy, and the Milky Way galaxy is the specific location of the Sun within the universe.

The correct answer is that the Sun converts mass into energy by nuclear fusion and is located in the Milky Way galaxy. This is because nuclear fusion is the process by which the Sun produces energy, and the Milky Way galaxy is the specific location of the Sun within the universe.

11. In our solar system, the orbits of the planets are best described as (Standard 1.1a):

A slightly eccentric ellipse with the planet at one of the foci

A very eccentric ellipse with the planet at one end of the foci

A slightly eccentric ellipse with the sun at one end of the foci

A very eccentric ellipse with the sun at one end of the foci

Circular with the sun at the center

The correct answer is "a slightly eccentric ellipse with the sun at one end of the foci" because the orbits of the planets in our solar system are not perfect circles but rather elliptical in shape. The sun is located at one of the foci of the ellipse, not at the center. The use of the term "slightly eccentric" suggests that the elliptical shape is not too elongated or flattened, but rather close to a circular shape.

Explanation

The correct answer is "a slightly eccentric ellipse with the sun at one end of the foci" because the orbits of the planets in our solar system are not perfect circles but rather elliptical in shape. The sun is located at one of the foci of the ellipse, not at the center. The use of the term "slightly eccentric" suggests that the elliptical shape is not too elongated or flattened, but rather close to a circular shape.

12. Which statement best explains when and how the solar system formed (Standard 1.2c)?

The solar system formed about 13 billion years ago from a giant cloud of gas and debris.

The solar system formed about five billion years ago from a giant cloud of gas and debris.

The solar system formed about 13 billion years ago from cosmic radiation.

The solar system formed about five billion years ago from cosmic radiation.

The solar system formed about 13 billion years ago from gravity.

The correct answer states that the solar system formed about five billion years ago from a giant cloud of gas and debris. This explanation aligns with the widely accepted scientific theory of the solar system's formation, known as the nebular hypothesis. According to this hypothesis, a giant molecular cloud collapsed under its own gravity, forming a spinning disk of gas and dust. Within this disk, the Sun formed at the center, while the remaining material gradually came together to form the planets, moons, asteroids, and comets of the solar system. The age of the solar system is estimated to be around 4.6 billion years, which is consistent with the given answer.
