From where does the solar wind originate

Solar wind originates from Coronal holes

Explanation:

The solar wind originates from the upper layer of the Sun, called the Corona. This plasma generally comprises of electrons, protons and alpha particles with motor vitality somewhere in the range of 0.5 and 10 keV.  It differs in thickness, temperature and speed after some time and over sun oriented scope and longitude.

The particles can get away from the Sun's gravity in light of their high vitality because of the high temperature of the crown, which is a consequence of the coronal attractive field.

i would expect light rain in pittsburgh throughout the following 24 to 48 hours. the lower/falling weights in urban areas toward the west demonstrate that a low weight framework is moving from west to east toward pittsburgh. low weight frameworks are ordinarily connected with precipitation. the way that you don't see a major drop in temperature in the more western urban areas demonstrates the low weight framework is moving with a warm front, so just light rain would be normal. substantial downpours or progressively vicious climate is just typically connected with chilly fronts, where the warm air is pushed up and over a cool front quickly. this quickly rising air (convection) is what gives you heavier torrential downpours, and other conceivably serious weather conditions.

heat from the core of the earth causes convection currents to occur in the mantle. these currents slowly move the crust around.
