Across
- 3. a sweet compound that contains energy for life
- 5. erosion when ice formations called glaciers slide down a mountain, picking up pieces of mountain with them
- 10. to make something
- 11. living things that produce their own food using photosynthesis

Down
- 1. an area that receives some sunlight and some shade each day
- 2. Processes by which rock, sand, and soil are broken down and carried away (i.e. weathering, glaciation)
- 3. an area free of direct sunlight (no sunlight is found)
- 4. Plants use the sun's energy to convert water and carbon dioxide into sugar and oxygen
- 6. Dioxide A gas that is breathed out from humans. Also, this gas is used by plants in photosynthesis
- 7. a gas that is found in nature that both humans and animals need to breath in to survive.
- 8. 6 or more hours of direct sunlight daily
- 9. erosion when streams, river, and oceans cut into the land wearing away the soil and rocks moving them elsewhere.
- 12. erosion when wind moves sand, dust and soil from one place to another; can be limited by planting trees and other plants
