Dunes which are curved and have their tails pointing into the wind are
Dunes <em>which appear</em> as more than a singular type are called:
According to the given question, we are asked to state the names and types <em>of dunes </em>which are curved and point towards the wind and the ones which <em>appear </em>as more than a singular type.
As a result of this, we can see that a sand dune is an <em>accumulation of sand particles </em>which are propagated by agents of air to one location and there are four main types of sand dunes of which parabolic and star dunes are part of them.
Therefore, the correct answers are parabolic and star dunes

About 3.8 billion years ago
Explanation:
Why would I explain?
The precipitation associated with a warm front typically arrives extensively ahead of the actual frontal boundary.
Rain transpires on the foremost fringe of a warm front. As warm air is slightly less viscous than cold air, it slowly rises over the cold air by gradual frontal lifting and permits precipitation to evolve ahead of the frontal edge.
Yet, while cool air at the surface lives forward of a warm front, relatively warmer air often is discovered above it as the warmer surface air after the front rises up and over the cool air below. If sufficient moisture is present, this can develop in precipitation along and forth of the front.
