Great introduction to geology and the science about Earth and other planets. It makes me want to read more book about geology or even go further into the field. The whole new world about rocks and why they are there are really fascinating which have so much things to learn about rocks (Igneous rock - đá magma, Metamorphic rock - đá biến chất, Sedimentary rock - đá trầm tích) and other things like earthquakes/ seismic wave (sóng địa chấn), the Earth's crust and mantle and other layers included lithosphere (thạch quyển), asthenosphere (quyển mềm) till the core of Earth, tsunami, plate tectonics (mảng kiến tạo), volcanoes, and even fossils - yes by study rocks you would know ton of stuffs about your fossil. Necessary knowledge and something I don't know much but need to know more from now on!
