The sun 🌞 is an incredibly hot sphere of gas that is generating energy.
Its core is particularly hot and dense .Here nuclei of hydrogen collide and fuse to form helium.
This reaction produce energy which ,among other things light and heats the solar system.
The energy passes through the radiation and convection zones to the surface,then through the sun's atmosphere into space.
Since most plastics are made from petroleum chemicals that cannot be replaced,there is a need for recycling.
Thermoplastic,such as polythene,are easy to recycle ♻️ because they can be re-melted.
Thermoplastic such as Bakelite, pose a problem as they cannot readily be broken down.
Rising level of these "greenhouse gases" such as carbon-dioxide ,which come from burning oil 🛢️ or forest land ,may trap so much heat the Earth could warm up by 4°c(7.2°f) over the next 50 years.
An ecosystem contains several different wildlife communities and their habitat.
Ecologist use the term to mean all the complicated interaction that take place among living and non-living thing in an area.
The various components of the ecosystem include sunshine, water 💦, nutrients in the soil , bacteria 🦠, plant 🌵 and animals.
Acid are widely used in idustry because they react so readily with other materials.For ex-Sulphuric acid is used in the production of dyes and pigments , artificial fibre , plastic soap 🧼 and explosive 🧨.The acid is made by sulphur and oxygen reacting together.
Burning fossil fuels to produce energy for use at home and in industry releases polluting gases into the air. The gases dissolve in water in the 🌨️ clouds to form Nitric acid and Sulphuric acid .This water falls as acid rain, which erodes stone 🪨 building 🏫 and statues 🗿,kill tress and aquatic life , and reduce the soil's fertility.
(ISRO) has achieved a significant milestone by successfully launching the Aditya-L1 spacecraft, an observatory designed to study the sun. ...
