What a great question !
The earth's orbit is elliptical, the ellipse has two foci (focuses), and the center
of the sun is at one of them. All true.
But the earth's orbit is so close to being circular that the distance between the
two foci isn't that great, and the other focus is inside the sun !
I'm not sure about Pluto, but I think that's true for all the other planets.
Currently, after Pluto was degraded to a dwarf planet. Neptune is the planet furthest away from the sun. about 30 AU away ( 1 Astronomical Unit equals Earths orbit around the sun). when it comes to dwarf planets however. there is a newly discovered one called Sedna. it has a very ecliptic orbit, but it is believed that at its furthest it will be over 900 AU away from the sun.
all volcanoes are caused by the earths plates moving toward each other and that is called convergent boundaries.
227,940,000km away
The plates on either side are moving away from each other.
Sometimes it causes earthquakes, as well as when earths plates move in opposite directions. But yes, volcanoes are also formed when these plates move out of place or away from each other, for example Hawaii. That is an example of plates sliding through the ocean which causes islands.
Tangent to orbit, north away, tangent to orbit, south away.
that it will be faster when closer to the sun than futher away
Rigel and Betelgeuse don't orbit each other. They are hundreds of light-years away from each other.
When earths plates move away from each other ( separate ) Volcanoes form.
Well, when earths plates move away from each other that's when it happens but move well then NO!
The changes in the distance from the sun (due to elliptical orbit) make marginal differences in the amount of energy recieved by the earth,. > The major contributor to seasonal differences is essentially due to the tilt from perpindicular of the earths rotational axis and the fact that the axis will remain parallel throughout the earths yearly orbit around the sun, so in the northern hemisphere the winter equinox is when the top of the axis is at maximum tilt away from the sun, resulting in diffused sunlight and less daylight hours.
It means the point where a planet, or other object, is farthest away from the Sun in its orbit.

The earth by its gravitational pull keeps the moon in its orbit. The earths gravitational pull and the Moon's inertia creates a force called the centripetal force which keeps the Moon in orbit.
Since the earths orbit is not exactly even, when we are closer to the earth it causes warmer seasons and when we are further away it causes colder seasons.)
