MSSC-51.1.1: Phases of the Moon
The phases of the moon are caused by two things: the moon's revolution around the Earth, and the angle between the sun, Earth, and moon. As the moon orbits around the Earth, different portions of the moon are lit by the sun's rays. The angle between the sun, Earth, and moon changes during the moon's orbit, causing us to see different portions of the lit side of the moon. This results in the different phases of the moon, such as the new moon, waxing crescent, first quarter, waxing gibbous, full moon, waning gibbous, third quarter, and waning crescent.
MSSC-51.2.1: Types of Eclipses
There are two types of eclipses: a lunar eclipse and a solar eclipse. A lunar eclipse occurs when the Earth passes between the sun and the moon, casting a shadow on the moon. This causes the moon to appear reddish in color, also known as a blood moon. A solar eclipse occurs when the moon passes between the sun and Earth, blocking out the sun's light and casting a shadow on Earth. There are different types of solar eclipses, including a total solar eclipse, partial solar eclipse, and annular solar eclipse.
MSSC-51.3.1: Characteristics of the Moon
The moon is Earth's only natural satellite and is the fifth-largest moon in the solar system. It is about 238,855 miles away from Earth and takes about 27.3 days to orbit around Earth. The moon's surface is covered in impact craters, mountains, and valleys, with no atmosphere, no liquid water, and no magnetic field. It is also much smaller and less dense than Earth, with only about 1/6th of Earth's gravity. The moon's temperature can range from -173 degrees Celsius to 127 degrees Celsius, depending on whether it's in direct sunlight or not. The moon's phases are also closely tied to Earth's tides, with peak high and low tides occurring during the full and new moon phases.
When is the amount of the lighted side of the moon seen from Earth the same?
The amount of the lighted side of the moon seen from Earth is the same during a full moon. At this point in the moon's orbit, the sun is directly behind the Earth and the moon is fully illuminated by the sun.
The darkest part of the moon’s shadow is called the _____.
penumbra correct?
No, the darkest part of the moon's shadow is called the umbra, not the penumbra. The penumbra is the lighter part of the shadow that surrounds the umbra during a lunar or solar eclipse.
The different shapes of the moon as seen from Earth are called _____.
eclipses or penumbra correct?
Neither eclipses nor penumbra are the correct answer. The different shapes of the moon as seen from Earth are called phases.
Why do temperatures on the moon’s surface vary so much?
Temperatures on the moon's surface vary so much because the moon has no atmosphere to trap in heat. During the two-week lunar day, the surface temperature can reach up to 127 degrees Celsius (260 degrees Fahrenheit) due to the direct exposure to the sun's radiation. However, during the two-week lunar night, the temperature can drop down to -173 degrees Celsius (-280 degrees Fahrenheit) as there is no atmosphere to retain heat and the surface cools rapidly. Additionally, the moon's surface is also covered in materials that have different thermal properties, with some areas being able to absorb and retain more heat than others.
The temperature of the moon’s surface varies greatly from day to night because the moon has _____.
sry i have no clue so cant ask if my answer is correct
