1Daily Warm-Up Exercises Day 9 Why do some igneous rocks have large crystals while others have small crystals or no crystals at all? Some form underground, where the temperature is very warm. The magma cools slowly, allowing large crystals to form. Others form at the surface, where the temperature is cooler. The lava cools quickly, so crystals don’t have time to get very big, and they may not form at all.

Essay Question What forces are constantly shaping and reshaping Earth’s surface? (Hint: constructive/ destructive) Earth processes are going all the time. Destructive processes break down landforms. These include weathering, erosion, and tectonic plates sinking and melting. Constructive processes build up. They include mountain building, deposition (sedimentation), and new crust formation.
