The changing ocean currents lead to climate cooling by bringing cooler breezes to places with higher climates. The cool breezes push the warm air out and leads to the drop of temperature
Electromagntic wave, such as an X-ray.
Explanation:
- Electromagnetic wave does not require any medium to travel. These waves propagate outwards from the source.
- They can travel even through the vacuum of outer space.
- The major source is the sun which emits radiation in the form of the Electromagnetic spectrum.
- These waves travel through oscillating electrical and magnetic fields generated by the oscillating charged particles.
- These waves oscillate in the perpendicular direction of planes concerning each other and are in form.
- Electromagnetic waves travel at speed of light.
That's the definition of "free fall".
We can never observe free-fall in our daily life on Earth. There's always
at least one other force besides gravity acting on a falling body, because
it's always falling through air.
