elliptical

Which planet do most known extrasolar planets most resemble

Jupiter Neptune

The planet that most extrasolar planets resembles Jupiter.

Jupiter(apex)
Most of the confirmed Exoplanets are larger gaseous planets with large masses. These are easier to detect and confirm due to their size. They most resemble Jupiter, although many are thought to be much larger than our largest planet.

Which planet experiences the smallest range of temperatures

earth has the smallest range of temperatures

Which is the first step in building a solar system from a solar nebula

An explosion disturbs the gas and dust in the nebula.

Not nuclear, it takes an extremely hight temperature for Fusion to occur with in the sun or any other star.

ADDED: Yes "nuclear". Fusion is one of the two type of nuclear reaction, the other being Fission.

What were the heavier elements in the universe formed by

They were formed in supernovae.

Sunspots are temporary disturbances in the sun's

Sunspots are the temporary dark spots on the surface of the sun, specifically the photosphere. Sunspots can get as big as 50,000 km long. Sunspots can interrupt terrestrial magnetism.
