Answer:
b) About 31 times more energy
Explanation:
Lot of people get confused with the way in which the earthquake magnitude is calculated. The scale for measuring the earthquakes is logarithmic, so every whole number increase in magnitude represents a tenfold increase in the measured amplitude. This results in every consecutive whole number the earthquake to be 33 times more powerful than the previous one, so the difference in power between magnitude 7 and magnitude 8 is 33 times. If we take magnitudes that are not consecutive numbers, like magnitude 6 and magnitude 8, then the difference in power will be around 1,000 times.
Answer:
tributary
Explanation:
A tributary or affluent is a stream or river that flows into a larger stream or main stem river or a lake. A tributary does not flow directly into a sea or ocean.
Answer:
The word region: an area or division, especially part of a country or the world having definable characteristics but not always fixed boundaries.
Explanation:
Geographers categorize regions in two basic ways: physical and cultural. Physical regions are defined by landform (continents and mountain ranges), climate, soil, and natural vegetation. Cultural regions are distinguished by such traits as language, politics, religion, economics, and industry.
