Yogita Ingle 6 years, 4 months ago

<th>

The land breeze is shallow.	However, the sea breeze is deep.
Land breezes are normally experienced during the winter and autumn. This is due to the cooler nights.	Sea breezes normally occur during the spring and summer seasons. This is due to the consequential differences between the land and water.
Land breezes’ pace span from 5 to 8 knots.	Sea breezes’ pace span from 10 to 20 knots.
The temperature might remain the same when the land breeze occurs.	Sea breeze tends to decrease the air temperature.
Land breezes usually blow dry winds.	While the sea breeze contains more amount of moisture due to the particles absorbed from the water bodies.

How rain watet harvesting can be done

Meghna Thapar 5 years, 10 months ago

The activity of collecting rainwater directly and store it in big tanks for later use, or making the rainwater percolate into ground more efficiently to recharge the ground water, is called rainwater harvesting.

Rainwater harvesting can be done in two ways:

Rooftop rainwater harvesting: In this method, the rainwater is collected from the rooftop to a storage tank through pipes. This water may contain soil particles from the roof and needs to be filtered before use. Instead of collecting rainwater in the tank, the pipes can go directly into the percolation pit in the ground. The water seeps into the soil to recharge or refill the ground water.
Rainwater harvesting from open spaces around buildings. Rainwater goes into the ground directly from the roadside.
