Consider the following statements about jet streams:
1. Jet streams are important component of westerly flow which influences weather in north and northwestern India.
2.The jet streams are found mainly in the upper atmosphere or in troposphere.
3. Jet streams generally follow a straight path.
4. Jet streams are caused by a combination of a planet's rotation on its axis and atmospheric heating

Jet streams are fast flowing; narrow air currents found in the upper atmosphere or in troposphere .The main jet streams are located near the altitude of the tropopause.
The path of the jet stream is meandering and wavy. Most of the jet streams flow west to east, except tropical easterly Jet stream which blows over India and Africa during the summer and play an important role in the precipitation in India.
Jet streams are caused by a combination of a planet's rotation on its axis and atmospheric heating (by solar radiation and, on some planets other than Earth, internal heat). Jet streams form near boundaries of adjacent air masses with significant differences in temperature, such as the polar region and the warmer air towards the equator.
