Why are most maps unable to accurately depict earth

Answers

Because of the curvature of the Earth, a 2-D map cannot accurately represent the correct size of different landmasses, distorting them.

Answer:

    Maps are instruments of communication, they serve to graphically represent a given area of terrestrial space. Maps and cartograms do not aim to represent all the information present on the surface, but only what the author wants to demonstrate.

  Therefore, the maps can be divided into several types and their classification varies according to the topic treated. For this reason, it is called thematic maps.

What are some of the environmental factors that produce areas of precipitation extremes, such as rain forests and deserts?

Answers

One environmental factor that produces precipitation extremes is the proximity to large bodies of water. For instance, in order for there to be large amounts of precipitation, such as in a rainforest, the rainforest must be located near a large body of water, such as a lake. A desert lacks precipitation because it is very far from large bodies of water. Another factor that effects the amount of precipitation is elevation. Higher elevated lands typically receive more precipitation than lower elevation areas.

What is the most likely place a metamorphic rock might form?

Answers

Metamorphic rocks are formed deep within the Earth

Metamorphic rocks most likely form beneath mountain ranges, where pressure and temperature conditions are ideal due to the thickening of continental crust during tectonic activities, such as plate collisions. These rocks are exposed at the surface through erosion and crustal uplift following the pattern known as the Barrovian sequence.

The most likely place a metamorphic rock might form is deep within continental crust, particularly beneath mountain ranges such as the Himalayas. This geological setting provides the necessary conditions of high pressure and temperature needed for metamorphism. Tectonic activities, like continental collisions, cause the crust to thicken, pushing rocks deeper, where they are subjected to these intense conditions.

For instance, during the formation of a mountain range when two continental plates collide, pressure (differential stress) and temperature rise significantly, metamorphosing the rock. As the mountains erode over time, the crust rebounds and uplift occurs, exposing the high-grade metamorphic rocks at the surface. This occurs in established patterns known as the Barrovian sequence, which indicates that the higher the grade of metamorphism, the deeper and closer the rocks are to the collision center.

The process is largely driven by the geothermal gradient and the additional heat from magmatic activities. Metamorphic rocks can also rise from deep within the Earth and form magma if they melt, which would later cool to become igneous rock. Geologists track metamorphic minerals like chlorite, garnet, andalusite, and sillimanite to understand these processes as these minerals form under specific conditions of temperature and pressure.

Knowing we are currently adding one billion people to the planet roughly every 12 years, approximately how many people are we then adding every year? How many every month?

Answers

Ok, so lets start of basic, how many people are added every 12 years?

Final answer:

We are adding approximately 83.3 million people to the planet every year and about 6.94 million people every month if we continue to add one billion people every 12 years. The global population is currently growing at an annual rate of 1.03 percent, signifying over 80 million additional individuals per year.

Explanation:

If we are adding one billion people to the planet every 12 years, we can calculate the number of people being added on a yearly and monthly basis by dividing the billion by the number of years and months, respectively. To find out the number of people added each year, divide one billion by 12, which gives approximately 83.3 million people per year. To calculate the number added each month, divide one billion by (12 years * 12 months per year), which equates to about 6.94 million people added each month.

Using these figures, along with the current growth rate of 1.03 percent per year, and assuming this rate continues, we can extrapolate population increases into the future. The global population growth is significant, as we're adding over 80 million people per year. If we were to maintain a 1% growth rate into the future, the Planet Earth would see its population increase significantly by 2100, likely surpassing well over 10 billion individuals.

What is the length of TU and OL?

Answers

so first, you put the two equations equaled to each other

2x - 14 = x + 2

next solve for the x

2x -x = 14 + 2

x = 16

After getting x (which is 16 in this case) plug it back into all x in the diagram
2x - 14 and x+2 to be exact

TU =2(16) - 14                       OL=16 + 2 
TU= 32 -14                             OL = 18
TU = 18                                  OL = 18

What is Continental crust?

The external part of Earth's lithosphere is known as the continental crust, is produced at the plate margins where the continental and oceanic tectonic plates subduct, creating the continents and continental shelves.

The uppermost part of the Earth's lithosphere, known as the oceanic crust, is created at transform boundaries on mid-ocean ridges that are found at diverging plate boundaries and is found under the oceans.

The density of the oceanic crust is 3.0 grams/cubic centimeter, whereas the density of the continental crust is 2.6 grams/cubic centimeter. Therefore, it is possible to argue that the density of continental crust is smaller than that of oceanic crust.

Cultural geography is the branch of geography that looks at the planet's physical features. As a result, choice (B) is the best way to respond.

What is cultural geography?

A division of human geography is cultural geography. Even though the first references to the study of various countries and cultures on Earth can be traced back to ancient geographers like Ptolemy or Strabo, cultural geography as an academic discipline first emerged as a counterargument to early 20th-century environmental determinist theories, which held that people and societies are governed by the environments in which they develop.

Cultural geography became fascinated with cultural landscapes rather than researching pre-determined regions based on environmental classifications. Carl O. Sauer of the University of California, Berkeley was in charge of it. He is known as the "founder of cultural geography." Because of this, American writers have long been at the forefront of cultural geography.

Hence, option (B) is accurate.

Which area of the united states lies mainly in a desert climate region?

Answers

Final answer:

The American Southwest, including parts of Texas, New Mexico, and Arizona, lies mainly in a desert climate region, characterized by arid conditions, low rainfall, and high sunlight exposure. The Great Basin, Mohave, and Sonoran deserts also contribute to the arid regions of the U.S.

Explanation:

The area of the United States that lies mainly in a desert climate region is primarily found in the American Southwest. This region includes states such as Texas, New Mexico, and Arizona. The Southwest is characterized by arid conditions, receiving low rainfall and a high amount of sunlight throughout the year. Particularly western Texas and states like New Mexico and Arizona are known for these arid climates. Water conservation projects are essential for supporting major metropolitan centers in these regions because of the scarcity of water caused by the desert conditions.

Another notable desert region in the United States is the Great Basin Desert, which is a cold desert that experiences freezing temperatures during the winter. Deserts like the Mohave and Sonoran are also found within the U.S. and are located on the lee side of mountain ranges, which creates a rain shadow effect, further contributing to the arid climate.
