There have been a number of scientific observations which led to the development of the Big Bang Theory. There observations are reported as observable fact without editorial judgement.
1] the spectra of light reaching us from distant stars appears shifted towards the red (lower energy) wavelengths.
2] there is an observable background radiation of 3 Kelvin everywhere we look.

Here’s what the Big Bang Theory says:
Learning objective:
To understand the distinction between climate an weather
To understand how low and high pressure areas affect local weather
To understand how storm fronts are formed
Do you know the difference between Climate and Weather?
What drives the earth’s climate?

Sound’s speed in seawater is of particular interest to anyone trying to use sonar or other underwater exploration techniques. The speed of sound in sea water is, on average, about 1560 m/s, or 3490 mph. But ocean waves are much slower:
Wave velocity is the speed of the wave. Velocities of normal ocean waves are about 90 km/hr while tsunami have velocities up to 950 km/hr (about as fast as jet airplanes), and thus move much more rapidly across ocean basins.

The Gulf Stream
From memory: sketch the north Atlantic ocean, draw and annotate the cold and warm sections of the gulf stream.
Q: England is as far north as central Canada yet its climate is about the same as New York’s. Explain why this is and why London is usually foggy.
The Gulf Stream is driven by the difference in water temperature between waters near the equator and waters near the north pole.
The Gulf Stream is a convection current.
