Question Q.17Briefly explain and differentiateGS1GS1

Briefly explain the process of tide formation and differentiate between tides and waves. (15 marks, 250 words)

Introduction

Tides are the periodic upward and downward movement of water level in water bodies due to gravitational force of celestial bodies.

Main Body

Tides -> help in fishing industry, facilitate tidal energy, soil and mineral enrichment.

Process of tide formation.

Two tides per day are seen usually - Spring tide (upward) and Neap tide (downward)

-i- Spring tide: [diagram showing water level increased due to combined gravity of moon and sun aligned with earth]

-ii- Neap tide. [diagram showing moon-earth-sun at right angle, water level balanced by gravity countering each other]

Tides usually occur twice a day on a difference of close to 12 hours.

Even though moon has lesser force than sun, its proximity increases its force.

Tides are also aided due to landform.

Helpful in myriad of ways

Difference between tides & waves.

Tide | Waves

Periodic upward & downward movement of water level. | water doesnot move, rather the energy make it seem moving

-iii- Occurs on a fixed frequency | continuously keep on moving.

-iii- Caused due to Gravity of celestial bodies | Winds affect the wave Eg: land breeze, sea breeze

-iv- Helps in harvesting tidal energy | Helps in getting tidal wave energy (less efficient than tides).

-v- Tides are more pronounced & deflects more water mass. | Occurs on a local level on the shore.
