What else can I help you with?
Why are continents not fixed permanently in location on the earths crust?
The continents are embedded in the top side of crustal plates which float on the surface of the mantle. Convection currents in the mantle carry the plates around and the embedded continents travel along.
Hoe does air circulate around earths surface?
Heat from the sun
What are the advantages and disadvantages of each way of showing earths surface?
by turning them around.

What describes how continents have moved around Earth's surface throughout Earth's history?
continental drift
Did wind push continents together?
No. The continents 'float' on a huge reservoir of magma - melted rock - and the deep underground/undersea forces push the continents slowly but unstoppably around on the surface of the globe.
What is the surface on which the lithospheric plates move around earths surface?
Lower mantle is the surface on which the lithospheric plates move around earths surface.
Which planets surface gravity is 38 percent that of earths?
Both mercury and mars have a gravity which is around 38% of earths. Mercury's gravity is 37.8% of earths, Mars' gravity is 37.7% of earths.
Did the earths continent shift?
Yes, the Earth's continents have shifted over millions of years due to plate tectonics. This movement has resulted in the formation of supercontinents, such as Pangaea, which eventually broke apart to form the continents we see today.
Which rocky planet has the strongest gravitational pull?
Of the four inner, rocky planets, Earth is the largest and most massive. As a consequence, it has the highest surface gravity of the four inner planets. The gravity for Venus is around 90% of Earths, while for Mars and Mercury the surface gravity is around 38% of Earths.
How did continental drift happen?
Continental Drift happened, when the tectonic plates in the earth shifted, and pushed the lithosphere up, causing our continents to split.
What planet has low air pressure and is mostly carbon dixide?
Mars has a thin atmosphere, mainly of Carbon Dioxide. Its surface pressure is around 0.7 kPa, around 0.7% of Earths surface pressure.
