Presentation transcript:

A solar eclipse happens when the moon blocks our view of the sun. This happens when the Moon is exactly between the Sun and the Earth.

Solar flares release huge amounts of high-energy particles and gases and are tremendously hot! solar flares can cause sunquakes A Solar wind is a continuous stream of ions (electrically charged particles) that are given off by magnetic anomalies on the Sun.ions A solar prominence (also known as a filament) is an arc of gas that erupts from the surface of the Sun. Prominences can loop hundreds of thousands of miles into space.

Tides are periodic rises and falls of large bodies of water. Tides are caused by the gravitational interaction between the Earth and the Moon. The gravitational attraction of the moon causes the oceans to bulge out in the direction of the moon. Another bulge occurs on the opposite side, since the Earth is also being pulled toward the moon (and away from the water on the far side). Since the earth is rotating while this is happening, two tides occur each day.

The water on the far end of the earth, away from the moon is always being pulled out from the center of the spinning earth.

When the moon is between the sun and the earth (at new moon), the sun’s gravitational pull is in the same direction as the moon’s. During these days the high tides are higher and the low tides are lower than they'd be with just the moon’s pull alone. This is called spring tide.

A solar prominence (also known as a filament) is an arc of gas that erupts from the surface of the Sun. Prominences can loop hundreds of thousands of miles into space. Spring tides are especially strong tides (they do not have anything to do with the season Spring). They occur when the Earth, the Sun, and the Moon are in a line. The gravitational forces of the Moon and the Sun both contribute to the tides. Spring tides occur during the full moon and the new moon.Sun

When the moon is in its first quarter or its last quarter, the sun’s gravitational pull is in perpendicular direction to that of the moon. The sun pulls water away from the areas of high tide to the areas of low tides, resulting in lower high tides and higher low tides. These are called neap tides.

Neap tides are especially weaker high tides. They occur when the gravitational forces of the Moon and the Sun are perpendicular to one another (with respect to the Earth). Neap tides occur during quarter moons.
