The currents of the mantle pull the crust above it through drag. The plates, therefore, move on top of the mantle. At San Andreas fault, the North American Plate met the Pacific plate. However, due to the presence of the Farallon plate that was disappearing into the mantle in a subduction zone, the Pacific and North American plates movements changed in their configuration. The two plates now move past each other. The San Andreas fault is, therefore, a strike-slip fault.
Answer:
Si4Br8
Explanation:
The chemical names are formed with prefix and suffix with helps in the formation of chemical formula. Example of prefix are mono- means one, “di-” means two, and “tri-” is three" and suffix are "ide". Prefix represents the number of elements present in the compound and so help in formation of chemical formula.
The formula for Tetrasilicon octabromide is Si4Br8 as "tetra" used as prefix which represents that there are 4 element of silicon present in the compound and "octa" used as prefix in bromide represents that there are 8 element of bromide present in the compound.
Hence, the correct answer is "Si4Br8".
Answer:The ocean takes up carbon dioxide through photosynthesis
Explanation: by plant-like organisms (phytoplankton), as well as by simple chemistry: carbon dioxide dissolves in water.As we burn fossil fuels and atmospheric carbon dioxide levels go up, the ocean absorbs more carbon dioxide to stay in balance.
