The energy in coal comes from energy that was stored in giant plants that lived hundreds of millions of years ago in swamp forests, even before the dinosaurs! When these giant plants and ferns died, they formed layers at the bottom of the swamps. Water and dirt began to pile up on top of the dead plant remains. Hope this helps. ♀️
Answer:
Physical features
Most of the Arabian Sea has depths that exceed 9,800 feet (2,990 metres), and there are no islands in the middle. Deep water reaches close to the bordering lands except in the northeast, off Pakistan and India.

Answer:
1. Without a calendar we could not know when to celebrate any of the festivals on particular days. We would even get the days of the week confused after a while. We would not be able to tell when a year had gone by, so it would be hard to keep track of someone's age.
2. Without numbers we wouldn't be able to count or measure anything. We would forget our age one day, and possibly forget how to count. Also we wouldn't be able to tell time, unless we used the sun. It would make life very problematic.
3. It would take very long to get us somewhere. We could no longer travel with airplanes, since they use wheels to take off. Such a simple thing as going to the grocery store, would turn into a huge task. Traveling would take very long to do, or might be non-existent if we didn't use horses.
Meteorology.
A meteorologist uses science to learn and understand a certain part of Earth's atmosphere, and uses that knowledge to predict weather patterns and how they will impact Earth's systems.
Answer:
True
Explanation:
Escape velocity is the speed needed for any freely moving object to run away from the gravitational pull of the massive body like the sun. This depends on the direction of movement as earth's escape velocity is 465m/s at the equator so a rocket would need a speed of 10.73 km from where the rocket would launch the surface velocity would impact it and the escape velocity would eventually decrease due to friction and gravity pull.
