By the electric shock

0Thank You

Yogita Ingle 7 years ago

A bulb is said to be fused because of low resistance path provided by broken filament ends which causes spark on account of electric discharge. More thinner the part of filament compared to rest, lesser will be the heat dissipation and more will be the thermal stress as more heat will be generated along thinner part than the rest of filament.

What is the importance of water cycle?

Posted by Sara Gufran 7 years ago

CBSE > Class 06 > Science (OLD)

1 answers

Yogita Ingle 7 years ago

The water cycle is important to all life on earth for many reasons. All living organisms require water and the water cycle describes the process of how water moves through the planet.
Plants wouldn't grow without precipitation (and thus anything consuming the plants wouldn't survive and so forth). Infiltration of water filters and cleans our water. Glaciers, ice, and snow can act as stores of freshwater for both humans and other organisms. Runoff contributes to rivers, other freshwater bodies, and eventually the ocean, sustaining freshwater and marine life.
