, the world was made up of a single continent through most of geologic
time. That continent eventually separated and drifted apart, forming
into the seven continents we have today. The first comprehensive theory
of continental drift was suggested by the German meteorologist Alfred Wegener
in 1912. The hypothesis asserts that the continents consist of lighter
rocks that rest on heavier crustal material—similar to the manner in
which icebergs float on water. Wegener contended that the relative
positions of the continents are not rigidly fixed but are slowly
moving—at a rate of about one yard per century.

Answer:
Hey!
Stars are formed from massive clouds of dust and gas in space CALLED NEBULAE. Gravity pulls the dust and gas together to form a PROTOSTAR...much like a baby star!
These gases come together, and as they do, the temperature begins to increase...
The finished stars are formed when the OPTIMUM TEMPERATURE is released for the chemical reactions within to start!
OUR SUN'S COLOUR IS WHITE! (Although its actually all the colours mixed together)
