How does seafloor crust differ from continental crust?

Seafloor crust is thinner, younger, and higher in density. Continental crust is made from volcanic rock called basalt, which is lower in density than what the seafloor crust is made from.

What is the main factor that makes earth more geologically active than the other terrestrial planets?

Why is Earth geologically active? Internal heat drives geological activity. – Larger the planet, more heat retained. – Circulation of liquid outer core creates Earth’s magnetic field.

Why does earth have the strongest magnetic field?

Why does Earth have the strongest magnetic field among the terrestrial worlds? It rotates much faster than any other terrestrial world. C) It is the only one that has both a partially molten metallic core and reasonably rapid rotation.

What are the four major geological 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. Earth has experienced many impacts, but most craters have been erased by other processes. We owe the existence of our atmosphere and oceans to volcanic outgassing.

What are the surface features of the planets?

Common surface features include:

  • Impact craters (though rarer on bodies with thick atmospheres, the largest being Hellas Planitia on Mars)
  • Dunes as found on Venus, Earth, Mars and Titan.
  • volcanoes and cryovolcanoes.
  • Rilles.
  • Mountains (the highest being Rheasilvia on 4 Vesta)
  • Escarpments.

What are 3 slow changes to the earth’s surface?

Earth changes in its own natural ways. Some changes are due to slow processes, such as erosion and weathering, and some changes are due to rapid processes, such as landslides, volcanic eruptions, Tsunamis and earthquakes.

What planets in our solar system have wind?

We’ll just skip methane-blue Uranus, because it’s another really windy gas giant. Same with Neptune, except even more X-treme! Neptune’s winds are the fastest in the solar system, reaching 1,600 miles per hour! Neptune has been known to have giant, spinning storms that could swallow the whole Earth.
