Question

In three short simple sentences, explain how the valleys and mountain ranges form. Make it look like a 8th grader wrote it

Answer 1

Valleys form when rivers or glaciers slowly carve out the land, or when the Earth's crust pulls apart. Mountain ranges form when tectonic plates smash together and push the ground up, or when volcanoes pile up lava and ash. Over millions of years, weather and erosion keep changing valleys and mountains into the shapes we see today.
