Across 4. horizontal layering in sedimentary rock 5. weathering process in which rocks are broken down into smaller pieces by temperature and pressure – but their chemical makeup is the same 11. mechanical weathering process that occurs when water repeatedly freezes and thaws within the crack or rocks, often resulting in rocks splitting. 12. rock that undergoes high pressure and temperature change deep within Earth’s crust 13. the changes that rocks go through as a result of temperature, pressure, and weathering 14. layers with in a rock that are caused by heat and pressure breaking the rock into sheets or flakes 15. weathering process in which the minerals that make up rocks are broken down into smaller particles due to chemical reactions- acid rain 16. the wearing away of materials by glacier movement

Down 1. process that breaks down rocks and minerals into smaller pieces but does not change their composition 2. record of Earth’s history from origin 4.6 billion years ago to the present 3. the process responsible for breaking down large rocks into smaller rocks and solid rock and soil 6. rock composed of layers of weathered material 7. rocks formed when magma cools and solidifies 8. ridge in the center of the ocean where new crust forms 9. the wearing away of materials by wind 10. the part of the Earth that is composed of the crust and the top part of the mantle
