Astronomy Review

Front

What is the primary reason water takes longer to heat compared to other substances?

Back

Water has a high specific heat capacity, meaning it requires more energy to change its temperature.

Front

What evidence supports the claim that the universe is constantly expanding?

Back

The redshift of distant galaxies indicates they are moving away from us, suggesting the universe is expanding.

Front

What are the two types of tides?

Back

Spring tides and neap tides.

Front

What is a neap tide?

Back

A neap tide occurs when the sun and moon are at right angles relative to the Earth, resulting in lower high tides and higher low tides.

Front

Define frequency in the context of waves.

Back

Frequency is the number of waves that pass a given point in a specific period of time, usually measured in Hertz (Hz).

Front

What is the primary celestial body responsible for the tides on Earth?

Back

The Moon's gravitational force is the primary cause of tides on Earth.

Front

How does the gravitational pull of the Moon affect ocean tides?

Back

The Moon's gravitational pull creates bulges in the ocean, leading to high tides in the areas closest to the Moon.

Front

What is the difference between high tide and low tide?

Back

High tide is when the water level is at its highest point, while low tide is when the water level is at its lowest point.

Front

What role does the Sun play in the formation of tides?

Back

The Sun's gravitational force also affects tides, but to a lesser extent than the Moon.

Front

What is the significance of the term 'specific heat capacity'?

Back

Specific heat capacity is the amount of heat required to raise the temperature of a unit mass of a substance by one degree Celsius.
