Which phrase describes a feature of a Mercator projection Is least commonly used sizes most features to scale present longitude
Komok [63]

Answer:

The correct answers are:

- is most commonly used;

Despite being a projection that is not the best representation, nor the most accurate one, still this map seems to be the most practical one for usage, so it is still the most popular one.

- presents longitude lines as parallel;

This projection is a cylindrical one, so all of the longitude lines are presented are lines that are parallel to one another.

- distorts land size as it moves away from the Equator;

The biggest problem with this projection is the distortion. The distortion becomes bigger and bigger with the increase in latitude, so it depicts the places around the poles as much larger than they actually are.

Write a paragraph explaining how the movie "The core" supports your knowledge of the following state indicator
Vadim26 [7]

Answer:

The outermost shell of a terrestrial planet is referred to as "crust." The Earth's crust is separated into two types: continental crust, which is older and thicker, and oceanic crust, which is younger and denser. Plate tectonics influences the dynamic geology of the Earth's crust. The outermost shell of a terrestrial planet is referred to as "crust."

The mantle is the layer immediately beneath the sima. With a thickness of 1800 miles, it is the Earth's thickest layer. The mantle is made up of extremely hot and thick rock. Under the weight of a huge load, this layer of granite even flows like asphalt. The flow is caused by large temperature differences between the mantle's bottom and top. The movement of the Earth's plates is due to the movement of the mantle! The mantle's temperature ranges from 1600 degrees Fahrenheit near the top to about 4000 degrees Fahrenheit near the bottom!
