# What is a Neap Tide?

Jan 26, 2018

Neap tides are the tides with the least difference between the high and low tides.
They are the two lowest high tides of the month.

#### Explanation:

Tides are caused by gravitational attraction from the moon and from the sun.

When the sun and moon are both pulling in the $s a m e$ direction, the tides get higher than usual.

But when the sun and moon are pulling at $r i g h t$ $a$$n g$$l$$e s$ to each other, the tides don't get as high as usual.

When the gravitational pull of the sun and moon are working together, it causes an unusually high tide called a spring tide.

When the gravitational pull of the sun and the moon are pulling at right angles to each other, it causes an unusually low high tide called a neap tide.

Here is a diagram showing how gravitational pull causes
