the sedimentary layers above an erosive surface are __________ relative to all rocks present below the surface.
Which principle states that in a sedimentary sequence, the oldest layer lies at the bottom and the youngest layer at the top
Answer: Principle of Superposition
Explanation: In an otherwise undisturbed sequence of sedimentary strata, or rock layers, the layers on the bottom are the oldest and layers above them are younger. Principle of Original Horizontality: Layers of rocks deposited from above, such as sediments and lava flows, are originally laid down horizontally. Hope this helps!
What is air pressure?
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.

In one or two sentences, explain why and how the map of africa has changed over time.
Answer:
When the first World Book was published in 1917, there were only two independent countries in Africa: Abyssinia (now Ethiopia) and Liberia. Together, they made up less than 5 percent of the land area of the continent. The rest of Africa was divided into colonies controlled by the European nations of Belgium, France, Germany, Italy, Portugal, Spain, and the United Kingdom.
Organized groups in some African colonies began demanding self-government early in the 1900’s. But a mass independence movement did not take shape until after World War II (1939-1945).
Some countries gained their independence relatively peacefully. In 1951, Libya, which was an Italian colony in 1917, became the first country in Africa to gain independence. In 1956, France granted Morocco and Tunisia independence. That same year, the United Kingdom granted Sudan independence as well. Other countries saw much bloodshed before their independence was granted. In Algeria, a bloody revolt raged against the French from 1954 until the country won independence in 1962. In Kenya, members of a movement called Mau Mau revolted against British control in the 1950’s. The revolt failed, but it contributed to Kenya’s eventual decolonization in 1963.
Explanation: Today, Africa is divided into 54 independent countries. Several European countries still control a few small islands: the Madeira Islands (controlled by Portugal), Mayotte and Réunion (France), and Saint Helena (United Kingdom).

what happens to a sedimentary rock if you apply heat and pressure?
Answer:
it turns into a nonfolaited metamorphic rock.
Answer:
It turns into metamorphic or igneous rock.
Explanation:
When sedimentary rocks are subjected to heat and/or pressure, they either change shape and become metamorphic rocks (foliated or non-foliated, depending on how the sediment was compacted) or melt and erupt as igneous rocks. They can also be reformed into new sedimentary rocks after being weathered and eroded.

if both a basin and a dome are composed solely of sedimentary beds that have been eroded such that thte ground surface is level. how would you idenfity each
There are different ways to identify an item. You can be able idenfity each by:
Domes and basins are said to be circular rock formations.Domes are formed by magma pushing up.Basins are formed by magma moving away and the land sinking down.For one to be able to tell the difference, know that Dome structures are situated where forces deep under the crust have thrust a part of the earth upward.
This makes the cuestas or overlapping folds face inward.
Basins often overlaps and thus face outward as the structure create a depression.
