Physical geography focuses on natural processes of the earth, including climate and plate tectonics, whereas human geography studies the effect and behavior of humans and how they relate to the physical world. The two fields of geography are interrelated.
A gravel covered plain is called a Reg. A reg is a desert basin where the sand has been blown away leaving a gravel covered plain.
The Earth's rocky outer crust solidified billions of
years ago, soon after the Earth formed. This crust is not a solid
shell; it is broken up into huge, thick plates that drift atop the soft,
underlying mantle.
The plates are made of rock and drift all over the globe; they move both
horizontally (sideways) and vertically (up and down). Over long
periods of time, the plates also change in size as their margins are
added to, crushed together, or pushed back into the Earth's mantle. These plates are from 50 to 250 miles (80 to 400 km) thick.
Answer:
Th similarities between the black hole and the neutron star is that they are formed from dead (dying) starts. But they come from different parent stars, if the parent star is 1.4 times the mass of the sun, a neutron star will be formed, but if the parent star is twice the mass of the sun a black hole is formed.
Explanation:
A black hole is defined as an area of space whereby the matter is so compacted that nothing can escape from it. This area is called <em>event horizon. </em>Black holes are formed when an enormous star dies in z supernova. They weigh at least twice the sun's mass, and their mass is directly proportional to their radii.
Neutron stars are created during supernova and maintained by a neutron called <em>degeneracy pressure.</em> Neutron star has a small radius, typically 30 km, with a very high density made up of compacted neutrons.
