What kind of surface features result from tectonic activity?

Earth’s magnetic field. C) Tidal forces. D) Lava flows in trenches along the sea floor. E) Convection cells in the mantle.

What features on the planet would you look for to detect past and present plate tectonic activity?

Topographic features revealing mountain ranges and deep valleys as well as volcanic activity would be indicators of plate tectonics, because these formations are consistent with plate existence.

What process has shaped the Earth’s surface more than any other?

What process has shaped Earth’s surface more than any other? shield volcano on Mars. How did the lunar maria form? Large impacts fractured the Moon’s lithosphere, allowing lava to fill the impact basins.

What would the surface of the Earth be like if there was no tectonic activity?

Erosion would continue to wear the mountains down, but with no tectonic activity to refresh them, over a few million years they would erode down to low rolling hills. So the whole planet would be flatter, and the topography would be a heck of a lot less exciting.

What are surface features of Earth?

Our home planet Earth is a rocky, terrestrial planet. It has a solid and active surface with mountains, valleys, canyons, plains and so much more. Earth is special because it is an ocean planet. Water covers 70\% of Earth’s surface.

What is on Earth’s surface?

[/caption]Most of the Earth surface, about 70\%, is covered with water. The remaining 30\% is made up of the seven continental landmasses. Underneath the water that fills the oceans, and the dirt and plants that cover the continents, the Earth’s surface layer is made of rock.

How is the Earth’s surface affected by the movement of the tectonic plates?

Plate motions cause mountains to rise where plates push together, or converge, and continents to fracture and oceans to form where plates pull apart, or diverge. The continents are embedded in the plates and drift passively with them, which over millions of years results in significant changes in Earth’s geography.

What are some features of Earth that make it distinct from other planets in the solar system?

Earth is a little more than 12,000 kilometers in diameter. It differs from the other planets because it has liquid water on its surface, maintains life, and has active plate movement. It rotates on its axis every 24 hours (a day) and revolves around the Sun every 365 days (a year).

What surface processes affect the earth?

Wind, water, and ice erode and shape the land. Volcanic activity and earthquakes alter the landscape in a dramatic and often violent manner. And on a much longer timescale, the movement of earth’s plates slowly reconfigures oceans and continents.

What are processes that shape Earth’s surface?

The physical processes on Earth create constant change. These processes—including movement in the tectonic plates in the crust, wind and water erosion, and deposition—shape features on Earth’s surface.

What would Earth look like without plate tectonics?

If the continents were eroded completely into the oceans there would be no continents and no land left. Without plate tectonics that push the continents up the erosion would result in the continents disappearing under the surface of the oceans.

What are 3 surface features?

Mountain ranges, subduction trenches, tectonic plates, and mid-ocean ridges are all visible in the image. The Earth’s surface is composed of rigid plates that move relative to each other.
