1.
When the ______________ hits Earth, and eclipse occurs.
Correct Answer
B. Moon's shadow
Explanation
When the moon's shadow hits Earth, an eclipse occurs. This is because during an eclipse, the moon passes between the sun and the Earth, casting its shadow on the Earth's surface. This can result in either a solar eclipse, when the moon blocks the sun, or a lunar eclipse, when the Earth blocks the sun's light from reaching the moon. In both cases, the moon's shadow plays a crucial role in creating the phenomenon of an eclipse.
2.
The word solar comes from the Latin word meaning..........
Correct Answer
sun
Sun
the sun
the Sun
Explanation
The word solar is derived from the Latin word for "sun". Latin is an ancient language and many scientific terms have their roots in Latin. In this case, the word solar refers to anything related to the sun. Therefore, all the options provided - sun, Sun, the sun, and the Sun - are correct explanations for the meaning of the word solar.
3.
When _____________ hits the moon, an eclipse occurs.
Correct Answer
B. Earth's shadow
Explanation
When Earth's shadow hits the moon, an eclipse occurs. This is because during an eclipse, the Earth comes between the Sun and the Moon, casting its shadow onto the Moon's surface. This blocks the sunlight from reaching the Moon, causing it to appear dark or partially obscured.
4.
Lunar comes from the Latin word for..........
Correct Answer
moon
the moon
Explanation
The word "Lunar" is derived from the Latin word for "moon" or "the moon". This suggests that the term "Lunar" is directly associated with the moon in some way.
5.
A ___________ occurs when the moon passes Earth and the Sun, blocking sunlight from the Earth.
Correct Answer
B. Solar eclipse
Explanation
A solar eclipse occurs when the moon passes between the Earth and the Sun, causing the moon to cast a shadow on the Earth and blocking sunlight from reaching certain areas. This phenomenon happens during the daytime when the moon aligns perfectly with the Sun, creating a temporary darkness as the moon covers the Sun's disk. Unlike a lunar eclipse, which occurs when the Earth blocks sunlight from reaching the moon, a solar eclipse is characterized by the moon obstructing sunlight from reaching the Earth.
6.
What is the darkest part of the moon's shadow?
Correct Answer
A. The umbra
Explanation
The darkest part of the moon's shadow is called the umbra. This is the region where all direct sunlight is blocked by the moon, resulting in a complete absence of light. The umbra is responsible for creating total solar eclipses when it falls on Earth's surface, causing a temporary darkness during the day.
7.
During a solar eclipse, people in the penumbra see a ________ eclipse.
Correct Answer
D. Partial
Explanation
During a solar eclipse, people in the penumbra see a partial eclipse. This is because the penumbra is the outer region of the shadow where only a portion of the light source is blocked. As a result, observers in the penumbra witness a partial obscuring of the Sun, where only a part of the Sun is covered by the Moon. This is different from a total or complete eclipse where the entire Sun is blocked.
8.
The moon's lighter but larger shadow is...........
Correct Answer
the penumbra
penumbra
Explanation
The moon's lighter but larger shadow is called the penumbra. The penumbra is the outer part of a shadow where only a portion of the light source is blocked. In the case of the moon, the penumbra is the area where sunlight is partially blocked by the Earth, resulting in a partial shadow. This is in contrast to the umbra, which is the darker and smaller shadow where the light source is completely blocked.
9.
A _________ occurs at a full moon when Earth is directly between the moon and the Sun.
Correct Answer
C. Lunar eclipse
Explanation
A lunar eclipse occurs at a full moon when Earth is directly between the moon and the Sun. During this event, the Earth's shadow falls on the moon, causing it to darken or appear reddish in color. This happens because the moon is not able to receive direct sunlight due to its alignment with the Earth and the Sun.
10.
What blocks the sunlight from reaching the moon during a lunar eclipse, causing the moon to look dark?
Correct Answer
Earth
the Earth
Explanation
During a lunar eclipse, the Earth comes between the Sun and the Moon, blocking the direct sunlight from reaching the Moon's surface. The Earth's shadow is cast onto the Moon, causing it to appear dark. This occurs because the Earth's atmosphere bends some of the sunlight around the Earth and into its shadow, resulting in a reddish glow on the Moon known as a "blood moon" during a total lunar eclipse.
