Freeze-Thaw: Drag the water into the rock using the mouse, but don’t touch the sides! Then, turn the temperature to freezing, causing the water to freeze and the rock to crack. Thermal Expansion: Using the mouse, quickly move the temperature slider left and right continuously to heat the rock up and down, which causes it to crack. Salt Crystal Growth: Drag the water into the rock using the mouse, but don’t touch the sides! Then turn the temperature to boiling, causing the water to evaporate and the rock to crack. Pressure Release: Move the rock layers above the rock using the mouse, which will remove the pressure from the rock and make it break. Vegetation Root Action: Search for the rock underground using your mouse, then click on it. The roots will grow on the rock and break it.
Pretty much finished. There might be a few bugs but I'm done with it for now. This is for extra credit in AICE Geography.
