Document Summary
Originates from the mountains of north vancouver, which are very rich in sediment and are transported along the river. Erodes the parallel mountains and bedrock whose sediment is later deposited sediment-rich water in the strait of georgia. Causes the delta to grow seaward and new landmass to be added. Form on earth"s surface, mostly from loose sediment that is deposited by moving water, air, or ice. If loose sediment is buried, it can be consolidated into hard rock over ime. May form by precipitaion of minerals from water or coral and other organisms. From when volcanoes erupt ash or lava or when molten rock crystallizes at depth. Rocks formed by changes in temperature, pressure, or deformaion. Can change sedimentary, igneous, or preexising metamorphic rocks. Rocks that precipitate directly from hot water. The present is the key to the past. The understanding of present-day geological processes in order to infer the processes that formed geologic structures and formaions throughout earth"s history.
