Question

A tide that occurs when the sun, earth, and moon are positioned to form a right triangle in space; high tides are lower than normal,while low tides are higher than normal.

Answer 1

These tides are known as Neap Tides. Spring Tides are tides formed when sun and moon are in straight line so the gravity pull by them is strongest but when they are at right angle to each other they cancel out the gravitational force of each other this leads to neap tides in which high tides are lower than normal,while low tides are higher than normal.

Answer 2

The  neap tide  is  tide that occur  when  sun,earth and  moon  are  positioned  to form  a  right triangle  in  space.The sun,earth and  the moon  form  a right angle and  the  gravitational  pull  of  the  sun  counteracts  the  pull  of  the  moon.This  neap  tide  occurs  when  the  difference  between  high  and  low  tide  is  least. In addition  the  neap  tide comes  twice  a month,in  the  first and  third  quarters  of  the  moon.
