Answer:

1. Earth rotates on its axis; this causes us to experience day and night.

2. The speed of light is 186000 miles per second

3. The four seasons happen because of the tilt of the Earth's axis. At different times of the year, the sun's rays hit different parts of the globe more directly. The angle of the Earth's axis tilts the Northern Hemisphere towards the sun during the summer.

Answer:

Seasons occur because of the tilt of the earth's axis which is at an angle of 23.5o. As the earth rotates, the sun rays hit different parts of the globe more directly than others... that's why in the UK its Summer when its Winter in Australia ie North/South hemisphere.

Google speed of light for eg mph, km/h etc but the exact figure is 299,792,458 metres per second

Why are solar winds potentially fatal for organisms living on earth?

Amiraneli [1.4K]

Solar winds contain high levels of radiation which could lead to various health related complications in living organisms on Earth. These complications include and are not limited to radiation sickness, chromosomal damage, and cancer. However, solar winds are blocked by the Earth's magnetic field, only posing problems to our telecommunications.
