Answer: It is the weight of air molecules pressing down on the earth.
Explanation: Without air, then their would be no living creatures roaming around on earth.
The air around you has weight, and it presses against everything it touches. That pressure is called atmospheric pressure, or air pressure. It is the force exerted on a surface by the air above it as gravity pulls it to Earth.
Atmospheric pressure is commonly measured with a barometer. In a barometer, a column of mercury in a glass tube rises or falls as the weight of the atmosphere changes. Meteorologists describe the atmospheric pressure by how high the mercury rises.
An atmosphere (atm) is a unit of measurement equal to the average air pressure at sea level at a temperature of 15 degrees Celsius (59 degrees Fahrenheit). One atmosphere is 1,013 millibars, or 760 millimeters (29.92 inches) of mercury.
Atmospheric pressure drops as altitude increases. The atmospheric pressure on Denali, Alaska, is about half that of Honolulu, Hawai'i. Honolulu is a city at sea level. Denali, also known as Mount McKinley, is the highest peak in North America.
As the pressure decreases, the amount of oxygen available to breathe also decreases. At very high altitudes, atmospheric pressure and available oxygen get so low that people can become sick and even die.
Mountain climbers use bottled oxygen when they ascend very high peaks. They also take time to get used to the altitude because quickly moving from higher pressure to lower pressure can cause decompression sickness. Decompression sickness, also called "the bends", is also a problem for scuba divers who come to the surface too quickly.
Aircraft create artificial pressure in the cabin so passengers remain comfortable while flying.
Atmospheric pressure is an indicator of weather. When a low-pressure system moves into an area, it usually leads to cloudiness, wind, and precipitation. High-pressure systems usually lead to fair, calm weather.

Is it possible to find gold in sedimentary rocks? If so, how? If not, why not?
Answer:
No
Explanation:
Gold is primarily found as a pure, native metal. Sylvanite and calaverite are gold-bearing minerals. Gold is usually found embedded in quartz veins, or placer stream gravel. It is mined in South Africa, the USA (Nevada, Alaska), Russia, Australia, and Canada. Quartz is a type of igneous rock and Sylvanite and calaverite are a type of rare metal, which when heated, leaves behind gold or gold-silver. So, simply put, no, you cannot find gold in sedimentary rocks.

From the locations of past coastlines and possible future coastlines, what conclusion can be made about how sea level is tied to glacial growth
The sea level is tied to glacial growth as a result of the changes that occur.
The glacial growth brings about a decrease in sea level.
Glacial growth occurs when water is evaporated and forms ice which is the
sold state of water as a result of the low temperature in the environment.
The ice formed brings about a decrease in sea level.
However, when the ice melts it leads to an increase in the sea level as the
liquid water formed from the ice which flows into the water bodies thereby
bringing about an increase.
