Answer:
Changes in the pressure create the flow of the air to move up and down in the ear and thus create popping sound.
Explanation:
- The ear-popping is caused by the phenomenon of the opening of the Eustachian tube when one swallows and it might be automatically when you blow our nose or are setting in an airplane and this sound is created when the air enters the middle ear through the tube.
A biggie: the transcontinental railroad. Because it would economically improve wherever it was, both the North and the South competed for the railroad to be in their respective territory, evidenced by the Kansas-Nebraska Act and the Gadsen Purchase and induction of California as a free state in 1860.
In addition: people could get land cheap because it was abundant and might leave to start afresh economically.
There's other stuff I can't remember as clearly, but there's a little and I hope it helps :)
The amount of LFG produced in a year from the calculations is 1.5768 * 10^8 cubic feet.
<h3>What is LFG? </h3>
The acronym LFG stands for land fill gas. It is a gas that is produced by the decomposition of biomass in a land fill. This gas can be burnt to generate steam. This steam is used to turn a turbine and generate electricity.
If 1 million tons of LFG is burnt in a day, then 365 million tons of LFG is burnt in one year.
1 million tons of waste produces 432,000 cubic feet of LFG
365 million tons of waste produces 365 million tons * 432,000 cubic feet /1 million tons
= 1.5768 * 10^8 cubic feet of LFG

Answer:
The seafloor is younger at the mid-ocean ridge, and as it gets further away from it is older and older.
Explanation:
The seafloor and its characteristics is one of the best evidence when it comes to the theory of plate tectonics. This was first noticed by Alfred Wegener and later by any other scienticsts that have been interested in this theory. Basically, the evidence lies in the fact that the seafloor is the youngest at the active mid-ocean ridge, and the further it is from it it gets older and older, with the oldest seafloor being found at the subduction zones.
The reason for this is the manner in which the seafloor forms. The high activity in the mantle below manages to break the crust of a preexisting plate and divide it. It pushes enormous amouns of magma toward the surface constantly for millions of years. The magma quickly solidifies and creates new seafloor as it gets in touch with the water. The magma that comes through pushes the already consolidated one aside and the process goes on for millions of years.
