NGSS.MS-PS1-2

• Dig burrows through the rock (e.g. rabbit, snakes, worms, etc.)

• Through waves it can carry rocks and make it break

• Can grow on rocks and cause it to break into pieces

• Blow bits of sand and small rocks that scratches the rock's surface

• Carries activities like mining, quarrying deforestation may weathered rocks
