tide flashcard..! ☆

Front

What is a spring tide?

Back

A spring tide occurs when the Moon, Earth, and Sun are aligned in a straight line, resulting in higher high tides and lower low tides.

Front

What is a neap tide?

Back

A neap tide occurs when the Moon, Earth, and Sun form a 90-degree angle, resulting in lower high tides and higher low tides.

Front

What happens during a new moon?

Back

During a new moon, the Moon is positioned between the Earth and the Sun, leading to higher tides due to the alignment of the Moon and Sun pulling on the Earth's waters.

Front

What is the effect of the Moon moving away from a body of water?

Back

When the Moon moves away from a body of water, low tides occur as the gravitational pull on the water decreases.

Front

How do tides affect swimming at the beach?

Back

Tides can significantly affect swimming conditions; high tides may provide deeper water, while low tides can expose more beach area and shallow water.

Front

What is the gravitational effect of the Sun on tides?

Back

The Sun's gravity also influences tides, but its effect is less than that of the Moon; however, during spring tides, the Sun enhances the tidal effect.

Front

What is the relationship between the Moon's phases and tides?

Back

The phases of the Moon (new moon and full moon) are associated with spring tides, while the first and third quarters are associated with neap tides.

Front

What is the significance of the alignment of the Earth, Moon, and Sun?

Back

The alignment of the Earth, Moon, and Sun determines the type of tide occurring: spring or neap tides.

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

How often do tides occur?

Back

Tides typically occur twice a day, with two high tides and two low tides in a 24-hour period.
