Question

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

Answer 1

Mountains form when Earth's plates smash together and push the ground up or when volcanoes spit out lava that piles up. Valleys form when rivers and glaciers slowly cut into the rocks or when plates pull apart and the land drops down. Over millions of years, these slow movements and erosion make the big ranges and low valleys we see today.
