Midterm Review 3/3

Front

What is a continuous spectrum?

Back

A continuous spectrum is a spectrum that contains all wavelengths emitted by a hot, dense light source, showing a smooth transition of colors without any gaps.

Front

What are neap tides?

Back

Neap tides are a type of tide that occurs when the Sun, Earth, and Moon form a right angle, causing the gravitational forces of the Sun and Moon to offset each other, resulting in lower high tides and higher low tides.

Front

What color does the Moon appear during a total lunar eclipse?

Back

During a total lunar eclipse, the Moon appears red due to Rayleigh scattering of sunlight through the Earth's atmosphere.

Front

What is an emission spectrum?

Back

An emission spectrum is a spectrum that shows colored lines of light emitted by hot gases, indicating the specific wavelengths of light that the gas emits.

Front

At what position could a solar eclipse occur?

Back

A solar eclipse could occur at position 1, where the Moon is directly between the Earth and the Sun.

Front

What is an absorption spectrum?

Back

An absorption spectrum is a spectrum that shows dark lines or bands superimposed on a continuous spectrum, indicating the wavelengths of light absorbed by a cooler gas.

Front

What causes the red color of the Moon during a lunar eclipse?

Back

The red color of the Moon during a lunar eclipse is caused by the scattering of sunlight through the Earth's atmosphere, which filters out the blue light.

Front

What is the difference between spring tides and neap tides?

Back

Spring tides occur when the Sun, Earth, and Moon are aligned, resulting in higher high tides and lower low tides, while neap tides occur when they form a right angle, leading to lower high tides and higher low tides.

Front

What is the significance of the position of the Moon during a solar eclipse?

Back

The position of the Moon during a solar eclipse is significant because it determines whether the eclipse is total, partial, or annular, based on the alignment with the Earth and Sun.

Front

What is the role of the Earth's atmosphere in lunar eclipses?

Back

The Earth's atmosphere plays a role in lunar eclipses by refracting and scattering sunlight, which causes the Moon to appear red.
