Two questions which arises in my mind about aurora borealis are:
- Why does aurora borealis occur?
- Why does aurora borealis occur in a particular time of the year?
Answers:
- As solar wind approaches the Earth, it meets the Earth's magnetic field. In the ionosphere, the ions of the solar wind collide with atoms of oxygen and nitrogen from the Earth's atmosphere. The energy released during these collisions causes aurora borealis.
- Aurora borealis is active the whole year. Since it needs to be dark in order to see aurora borealis in the sky, late August/September through the very beginning of April is the best time to go to a destination located in the aurora zone for a chance to see them.
Note: These are the questions which arises in my mind only. It may differ from person to person.

Answer:
The Colorado River (that is The lost river) proceeds from Rocky mountains into the Gulf of Calfornia. At the US & Mexico border, the Colorado river deflects into the farmland & orchards of different states of USA eldorado valley and other smaller basins.
After eight weeks of running through its delta, the fresh waters of the Colorado River meets the high tides of the briny sea.
Colorado’s nutrient-rich freshwater used to mixed with the Upper Gulf’s salty tides to create the perfect water chemistry and nursery grounds various water creatures of great commercial and cultural importance to the region, this was prior to the construction of big dams and diversions of the 20th century.
