Energy in South Africa describes energy and electricity production, consumption and export in South Africa. South Africa was 6. top hard coal producer in 2009. Hard coal production was 1,620 TWh in 2009 and total energy production 1,995 TWh in 2008.
The difference between the two mentioned magnitudes is 4.
A magnitude 1 earth-quack is 10000 times bigger than a magnitude -3 earth-quack. On the other hand, it is 1000000 times stronger in terms of energy release.
Note: To calculate the difference in energy between two earth-quacks, first you calculate the difference between their magnitudes and then you raise 10 to the output you obtain.
Answer:
Five largest cities in the US
1. Alabama
2. Alaska
3. Arizona
4. Arkansas
5. California
Explanation:
Physical features of these cities
1. Alabama: Montgomery is the state capital and site of many landmark civil rights events, like the Montgomery bus boycotts throughout 1955 and 1956 and the Selma-to-Montgomery March for voting rights in 1965.
The nation’s oldest baseball field, Rickwood Field, which opened in 1910, is located in Birmingham.
2. Arizona: Phoenix is the most populous state capital with approximately 1.5 million people living there. According to the National Climatic Data Center, the sun shines on Phoenix for 85 percent of its daylight hours.
3. Arkansas: Little Rock became the capital of the territory of Arkansas in 1821. The name “little rock” comes from the French explorer Bernard de la Harpe. In 1722, he saw rock formations jutting out from the Ouachita Mountains and named one group the big rock and the other the little rock.
4. California: this is the third largest city in the United States. California boasts mountains that are visible from just about anywhere in the state. Two main mountain ranges dominate: the Sierra Nevada and the Coast Range. The Coast Range runs from the northwest all the way down to the Mexican border, across 800 miles of terrain.
Answer:
Subduction zones are collision between two tectonics plates such that one of the plates is subducted to the mantle (or sinks) directly below the other plate
Whereby the densities of the convergent (colliding) continental plates are lower than the density of the mantle, subduction is prevented from occurring, and subduction zones are not formed at the continental-continental convergent boundaries
Explanation:
<span>Geography and their environment are very influential on a region’s economic activity. For example, most major U.S. cities, including New York City, Chicago, and Boston, are all located near water. This is because when these cities were founded, water was the main mode of transportation. The environment also has many economic consequences, including the type of crops that can be grown and whether or not different activities can take place outdoors.</span>
