What are the major processes that shape planetary surfaces after solar system formation quizlet?

To answer this, we must start with an understanding of the processes that cause planetary surfaces to change: volcanism, tectonics, erosion, and impacts.

What are the two reasons that the Earth appears to have relatively few impact craters choose all that apply?

There are so few craters on the Earth because most have been destroyed due to plate tectonics and erosion. There are so few craters on Venus because lava flows have filled in the craters. Also, both planets have atmospheres, which cause the smaller meteoroids to vaporize or broken up into smaller pieces.

What processes affect the surfaces of terrestrial planets?

Terrestrial planets have hard surfaces that can be re-shaped by several different processes: impact cratering, volcanism, erosion, and tectonics.

What are the four major geologic processes that can shape a planet’s surface?

What processes shape Earth’s surface? The four major geological processes are impact cratering, volcanism, tectonics, and erosion.

Why did the terrestrial worlds turn out so differently?

Why did the terrestrial worlds undergo differentiation? Why have larger worlds retained more internal heat than smaller ones? Differentiation- the process by which gravity separates materials according to density, with high-density materials sinking and low-density materials rising.

What are four major geological features on the surface of the moon?

The lunar landscape is characterized by impact craters, their ejecta, a few volcanoes, hills, lava flows and depressions filled by magma.

Is the moon just a big rock?

The composition of the Moon is much like that of the Earth. Its rocks are similar to Earth rocks and contain many but not all of the same minerals. Gradually, the lava ocean cooled and solidified, forming the light-colored crust we call the lunar highlands, which still covers 80 percent of the Moon.

Is there titanium on the Moon?

Titanium on the moon is primarily found in the mineral ilmenite, a compound that contains iron, titanium and oxygen. Charged particles from solar wind and micrometeorite impacts can change the moon’s surface materials, pulverizing rock into a fine powder and altering the chemical composition of the lunar surface.

How hot is the core of the moon?

about 2,420 to 2,600 F

Does the Earth’s core heat the earth?

As a result, much of the planet’s primordial heat, from when the earth first accreted and developed its core, has been retained. Additionally, descent of the dense iron-rich material that makes up the core of the planet to the center would produce heating on the order of 2,000 kelvins (about 3,000 degrees F).

How hot is the crust of the earth?

The upper crust withstands the ambient temperature of the atmosphere or ocean—hot in arid deserts and freezing in ocean trenches. Near the Moho, the temperature of the crust ranges from 200° Celsius (392° Fahrenheit) to 400° Celsius (752° Fahrenheit).

What is energy from the internal heat of the Earth called?

geothermal

What helps keep the Earth’s heat inside the Earth?

For all this, however, Marone says, the vast majority of the heat in Earth’s interior—up to 90 percent—is fueled by the decaying of radioactive isotopes like Potassium 40, Uranium 238, 235, and Thorium 232 contained within the mantle. Radioactivity is present not only in the mantle, but in the rocks of Earth’s crust.

What is in the core of Earth?

At the center of the Earth is the core, which has two parts. The solid, inner core of iron has a radius of about 760 miles (about 1,220 km), according to NASA. It is surrounded by a liquid, outer core composed of a nickel-iron alloy. The inner core spins at a different speed than the rest of the planet.
