Lightning does not come after thunder. Thunder is the sound produced from lightning. The amount of time in between when you see the lightning and when you hear the thunder makes you think that the thunder comes first but it is in fact the other way around.

Thunder comes after lightning because lightning is caused by a rapid heating and expansion of the air around it. This sudden expansion creates a shock wave, which we hear as thunder. Since light travels faster than sound, we see the lightning first before hearing the thunder.
Because sound is slower than light; The speed of Sound is 1,125 feet per second and the speed of light is 386,000 miles per second (avg speeds given). When the "Event" happens light travels out from it much faster than sound so you see it before you hear it (relative to your distance from the event).
The light from the lightning travels at the speed of light, whereas the sound (thunder) travels much slower.
No, thunder does not come from the ground. Thunder is caused by the rapid expansion of air surrounding a lightning bolt, creating a shockwave that we hear as thunder.
Lightning is caused by the buildup of electric charges in a storm cloud. When the charge difference becomes strong enough, it discharges as a lightning bolt. Thunder is the sound produced by the rapid expansion and heating of air surrounding the lightning bolt.
No, the two are quite different. The main difference is lightning is light, thunder is sound. Lightning is an electric charge that can come from a cloud for various reasons. Thunder is the sound made by lightning. Since sound travels slower than light, lightning comes first, thunder second.
Lightning is an electric discharge from the cloud to ground (although you can have other types, such as cloud to cloud). When the lightning strikes it heats up the surrounding air so fast that it causes an explosion, which is heard as thunder.
Thunder is "heleleʻi" and lightning is "ainalā" in Hawaiian.
