Question

1. which of the following best describes the main idea of the text? a. while partial eclipses of the sun can be dangerous, full eclipses of the sun are safe for people to view. b. both solar and lunar eclipses are caused solely by the orbit of earth around the sun and the spinning of earth itself. c. people often damage their eyes when watching lunar eclipses because of the dangerous radiation from the moon. d. both solar and lunar eclipses are caused by the movement of earth and the moon, and can be viewed safely with protective gear. 2. which of the following describes the main difference between a solar and lunar eclipse? a. how often the eclipses occur b. where you can see the eclipse from c. which heavenly body is casting the shadow d. how small or large the heavenly body appears 3. which detail best supports the idea that studying eclipses is useful? a. \what people see from earth during a partial lunar eclipse depends on how the sun, earth and moon are lined up.\ (paragraph 5) b. \people standing in the penumbra will see a partial eclipse. people standing in the umbra will see a total eclipse.\ (paragraph 12) c. \during an annular eclipse, nasa uses ground and space instruments to view the corona when the moon blocks the suns glare.\ (paragraph 16) d. \anyone within the path of totality can see one of natures most awe - inspiring sights — a total solar eclipse.\ (paragraph 17)

Explanation:

1. The text emphasizes the danger of the sun during solar eclipses, stating that while partial eclipses are safe to view, the sun can be dangerous during full solar eclipses.
2. Solar eclipses occur when the moon blocks the sun's light, and lunar eclipses occur when the Earth's shadow falls on the moon. The main difference is the cause - the moon's position in solar eclipses and the Earth's shadow in lunar eclipses. Also, solar eclipses require protective gear to view safely.
3. Studying eclipses is useful as it shows how the sun, Earth, and moon are lined up. People standing in the penumbra will see a partial eclipse and in the umbra will see a total eclipse.

Answer:

1. A. While partial eclipses of the sun can be safe for people to view, full eclipses of the sun are dangerous.
2. C. The main difference between a solar and lunar eclipse is that solar eclipses are caused by the movement of the moon blocking the sun and require protective gear to view safely, while lunar eclipses are caused by the Earth's shadow falling on the moon and can be viewed safely without special gear.
3. A. "What people see from Earth during a partial lunar eclipse depends on how the sun, Earth and moon are lined up."
