उत्तर
| S.No. | Spring tide | Neap tide |
| (i) | When the Sun, Moon and Earth aligned in the same line, the collective gravitation pull of the Sun and Moon on earth’s water strengthens to form a high tide known as spring tide. | When the Sun and Moon are at right angles their gravitational forces work against each other causing a low tide called Neap tide. |
| (ii) | These tides always occur on Full moon and New moon days. | A Neap tide occurs between two spring tides, i.e., twice a month when the first and last quarter moon appears. |
