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.

A precious natural resource was found below a lake in 1914. Today the lake's surface is a thicket of derricks. Wealth from this resource has helped make this country one of the richest in Latin America. What resource was found? What is the name of the lake? What is the name of the wealthy country?
The precious natural resource that found during exploration below the lake in 1914 is natural oil (crude oil).
The lake was known as Lake Maracaibo in the country called Venezuela which is located in South American (Latin America).
The oil which was discovered in Lake Maracaibo sits above one of the world's largest oil fields. Today the lake's surface is filled with thicket of oil derricks and the economic wealth derived from the oil exportation has helped Venezuela to become one of the richest countries in Latin america.In conclusion, the precious natural resource that found during exploration below the lake in 1914 is natural oil (crude oil).

facts about Deforestation
Answer:
Deforestation is when you clear a forest or treeline but cutting them down.
Explanation:
It can be bad and good in many ways. It can make space for Urbanization (Population that moves into an area) bit it can mess up the atmosphere because the carbon dioxide that the trees intake will be out in the open air as soon as it gets cut down.
Answer:
There are many conflicts as well as benefits caused by Deforestation that I'll list below.
Explanation:
Deforestation causes greenhouse gases like carbon dioxide to leak into the atmosphere. Over time this accumulates and warms our planet, this is how Global Warming happens.
The actions of deforestation, as in cutting down trees, destroy the habitats of animals that once lived there.
Agriculture expansion is a benefit of deforestation, like the construction of roads, urbanization, and croplands.
If the diagram illustrates Earth's relative position on December 21 of a given year, which of the following statements would be correct?
According to the image, we can say that on December 21st, the tropic of cancer will have a shorter day and with less intensity of solar radiation, as shown in the last answer option.
We can arrive at this answer because:
As we can see in the image, the tropic of cancer is not receiving sunlight directly.This is because the position of the earth makes the tropic of cancer receive less sunlight.There is a direct link between the intensity of sunlight that a region receives and the length of the day in that region. Therefore, if the tropic of cancer is not receiving much sunlight, this region will have a shorter day.
The answer options are in the attached image,

Lawrence, ks and nashville, tn occupy similar latitudes. Based on your knowledge of biomes, why is one found in a grassland and the other in a forest biome?.
Answer:Nashville is located several hundred miles east of Lawrence where considerably more precipitation falls. This occurs primarily due to the climate factor of 'continentality', which is essentially proximity to a large body of water. Nashville receives moisture from both the Gulf of Mexico and Atlantic Ocean, whereas Lawrence is much farther from large bodies of water, and, therefore, major sources of moisture. As a result, the average precipitation in Lawrence is barely half that of Nashville, which can only support grasslands.
Explanation:
One is closer to the ocean than the other, or their geographical settings—mountain ranges, etc. affect their biome classification. Their lack of plant life places them both in the same category.
Why do the same biomes exist in different locations?These biomes' variations can be attributed to climatic variations and their locations in regard to the equator. The sun's rays' angle of incidence on the various regions of the Earth's curving surface affects global temperatures.
Lawrence is far further from substantial bodies of water and, consequently, an important source of precipitation than Nashville, which receives moisture from both the Atlantic Ocean and the Gulf of Mexico. Because Nashville can only maintain grasslands, Lawrence's average annual precipitation is only slightly higher than Nashville's.

Describe why scientists use two different models to represent the layers of the Earth.
Answer:
Scientists use models to help them understand and explain ideas. Models explain objects or systems in a more simple way. Models often only show only a part of a system. The real situation is more complicated. Models help scientists to make predictions about complex systems. Some models are something that you can see or touch. Other types of models use an idea or numbers. Each type is useful in certain ways.
Explanation:
Physical Models
A physical model is a representation of something using objects. It can be three-dimensional, like a globe. It can also be a two-dimensional drawing or diagram. Models are usually smaller and simpler than the real object. They most likely leave out some parts, but contain the important parts. In a good model the parts are made or drawn to scale. Physical models allow us to see, feel and move their parts. This allows us to better understand the real system.
