The answer for this question is B: HydroElectric Power
Answer:
A particle or packet of light.
Explanation:
A photon essentially doesn't have a charge and thus can't be called an electron. So, option 1 is incorrect.
Photons are in fact packets of electromagnetic energy that light is made up of. So, option 2 is correct.
A photon is not a gaseous mass that indicates the preliminary stage in a star's growth and thus can't be a protostar. So, option 3 is incorrect.
Photons having different energies are constituents of the electromagnetic spectrum and thus a single photon can't be a spectrum. So, option 4 is incorrect.
Answer:
Earth's tilted axis causes the seasons. Throughout the year, different parts of Earth receive the Sun's most direct rays. So, when the North Pole tilts toward the Sun, it's summer in the Northern Hemisphere. And when the South Pole tilts toward the Sun, it's winter in the Northern Hemisphere.
Answer:
<u>In glaciers, North and South poles and some lakes.</u>
Explanation:
- As more than 70% of freshwater can be found in continental glaciers around the world. The rest is in icecaps and 0.5 % store in lakes and rivers, and swamps.
- Rest if possible may be found in the groundwater aquifers, hidden in remote and cut off lace of the world.
- Antarctica and arctic alone consist of a huge share of freshwater in the world which is stored in ice forms. While 97% of oceanic water is saline not fit for drinking.
- Various techniques are available for desalination of water but most of it not suitable for long term use. As it may have bacteria and harmful effects on the body. Due to climate change release of methane gas and other harmful greenhouse gases are quickly melting and depleting the freshwater r
