What occurs on the side of Earth that is closest to the moon and on the opposite side of Earth?
Gravity and inertia act in opposition on the Earth’s oceans, creating tidal bulges on opposite sites of the planet. On the “near” side of the Earth (the side facing the moon), the gravitational force of the moon pulls the ocean’s waters toward it, creating one bulge.
What type of tide occurs when the gravity of the sun and moon pull Earth’s surface in the same direction?
A spring tide occurs when the gravitational pull of both Moon and the Sun is in the same direction, making high tides higher and low tides lower and creating a large tidal range.
What type of tide occurs when the Earth is closest to the moon?
perigean spring tide
A perigean spring tide occurs when the moon is either new or full and closest to Earth. Often between 6-8 times a year, the new or full moon coincides closely in time with the perigee of the moon — the point when the moon is closest to the Earth. These occurrences are often called ‘perigean spring tides.
What are neap and spring tides?
Rather, the term is derived from the concept of the tide “springing forth.” Spring tides occur twice each lunar month all year long without regard to the season. Neap tides, which also occur twice a month, happen when the sun and moon are at right angles to each other. This occurs twice each month.
What neap tides are?
A neap tide—seven days after a spring tide—refers to a period of moderate tides when the sun and moon are at right angles to each other. During full or new moons—which occur when the Earth, sun, and moon are nearly in alignment—average tidal ranges are slightly larger.
Why is the high tide on the opposite side of the moon called?
As the ocean bulges toward the moon, a high tide is created. The high tide on the side of the Earth facing the moon is called the high high tide. The high tide caused by the bulge on the opposite side of the Earth is called the low high tide.
What’s the name of the high tide on the Earth?
Earth’s Tides. The high tide on the side of the Earth facing the moon is called the high high tide. The high tide caused by the bulge on the opposite side of the Earth is called the low high tide.
What makes the tides move around the Earth?
Tides move around Earth as bulges in the ocean. As the ocean bulges toward the moon, a high tide is created. The high tide on the side of Earth facing the moon is called the high high tide. The high tide caused by the bulge on the opposite side of Earth is called the low high tide.
When do the Sun and Moon align for spring tides?
Figure 14.13: Spring tides occur when the Earth, the Sun, and the Moon are aligned, increasing the gravitational pull on the oceans. Sometimes, the Sun and Moon are on opposite sides of the Earth while at other times, they are on the same side.
