Eyf the statement is true. If not then review the underline e the statement true. 1. The core accretion is the process of the Earth's formation by which the high velocity impacts from the cloud of gas and dust was converted to heat energy. 2. Gravity causes adiabatic compression where heat is generated as materials are compressed 3. Internal expansion of the Earth causes the planet to heat up internally. 4. The process by which Earth continuously generate heat is called radioactive decay. 5. A lot of Earth's heat is leftover from when our planet formed four-and-a- half billion years ago. 6. Magma originates in the lithosphere. 7. The addition of water and carbon dioxide to rocks deep in the planet generates magma. 8. Magma can also be created when hot, liquid rock intrudes into the earth's mantle. 9. The Earth's internal heat produces some cyclic displacements called convection, which causes the formation of magma through decompression melting in the planet's mantle. 10. The correct order of the different types of magma with lowest to highest silica content is felsic, intermediate, mafic, ultramafic. 11. The change in pressure and temperature causes chemical reactions in rocks to adjust and stabilize in the new pressure and temperature conditions. 12. Stress causes the change of the rock's appearance or commonly known as deformation 13. Chemical changes in rocks that undergo high grade metamorphism takes place at relatively high temperature and low pressure 14. Ductile deformation is when the high pressure conditions makes a rock, softer, less brittle, and more ductile. 5. Metasomatism is the chemical alteration of rocks by fluids containing dissolved ions.
