Give three examples of areas impacted by earthquakes in South Africa?

Answers

Answer 1
South Africa is in the vicinity of the African rift system, which is being pulled by a few millimeters annually. The earthquakes in here are caused by the slip on the fault line and by the release of stored elastic energy, but also some of the mining activities can contribute to the earthquakes.
Examples:
1. 29.09.1969, (near Tulbagh) the strongest and most destructive so far with 6.3 on the Richter scale.
2. 09.03.2005, (Stilfontein, North West) 5.3 on Richter scale, two miners killed.
3. 05.08.2014, (near Orkney, North West) 5.5 on Richter scale, lasted for 90 seconds, felt in Botswana and Durban as well.

The statement above is FALSE.
The early indigenous population of Central America were FARMERS.
The Central America is close to the sea, it has fertile soil, it has high amount of rainfall anually and it has tropical climate, these conditions make it a suitable place for cultivation of different crops. 
I would think this would be false as some of the early inhabitants of Central America were the Mayas and their kingdoms were mostly inland so I believe they were mainly farmers involved in agriculture rather than mainly fishermen.

ANSWER:

A wave cut platform is a 'flat bench like surface'.

EXPLANATION:

This a narrow flat area that is found along a shoreline. The area is created because of erosion caused by water that hits the shoreline.A 'wave cut platform' can be easily seen when the tide is low. 'Wave cut platforms' are usually huge areas of 'flat rocks'. These are mostly formed because of the cliff erosion and the rocks are more resistant that undergo weathering but are rarely carried away by water.

What sequence of events led to the origin of the Himalayas in Asia??

Answers

The Himalayan mountain range in Asia formed as a result of the collision of the Indian tectonic plate and the Eurasian tectonic plate. The Indian tectonic plate was once a big island, but it started moving towards Asia, when it finally reached it they collided. Both of the plates have the same density, that resulted in none of them to be submerged, but instead to press against each other and thus start lifting the land. Over time the Himalayan mountain range formed, and till this day this process continues and it is still lifting up.

When a galaxy is observed moving toward the earth, what visible radiation (as in, which color) will it emit?

Answers

It will emit Red because it is moving towards (which creates heat) instead of away (which is blue and cooler).

I hope this helps!

Answer:

When a galaxy moves towards the earth, it will emit blue colour light.

Doppler blueshift occurs when the source of light is coming near to its observer. Alternatively, Doppler redshift occurs when the emitter of light moves away from its observer.

Blueshift occurs when wavelength of light decreases. Redshift occurs when wavelength of light increases.

Blueshift makes the colour of the light move from red towards blue.

The shift in wavelength is determined by observing the spectrum with a spectrometer.

Which region of the early universe was most likely to become a galaxy? which region of the early universe was most likely to become a galaxy? a region whose matter density was lower than average a region whose matter density was higher than average a region with an unusual concentration of dark energy?

Answers

The answer is : a region with an unusual concentration of dark energy. A region whose dark matter density was higher than average, because gravitational runaway takes regions that are initially denser and makes them the more denser.

Answer:

The region of the 'early universe' whose matter density was higher than the average was most likely to become a 'galaxy'.

Explanation:

For an object to be subjected to gravity, it needs to have a specifically higher density. During the formation of galaxies in the early universe, 'the action of gravity' within and over the dense regions of the universe is believed to have 'played a significant role'. The regions which are found in the universe denser than average were the regions where the 'first galaxies of the universe' were formed.

Which two aspects of climate change appear to be having the most impact on forests?

Answers

The two biggest aspects of the global climate change that impact the forests are the temperature and the precipitation. The temperature increases globally, this affects the forests because the trees are adapted on certain temperatures, but now are faced with rapid increase of the same, and the time for adaptation is much shortened, so lots of forests degrade or gradually die off. The precipitation is a crucial factor for all plants. The forests are on places where there's sufficient amount of precipitation, but now lots of regions in the world are suffering from reduced precipitation, this also causes the degrading and dying off of the forests.

An agribusiness investor is weighing viable investment options. Which of the following opportunities would a financial adviser be LEAST likely to recommend based on market conditions?

I. Selling cattle to nomadic farmers in Eastern Africa
II. Selling drought-resistant seeds to farmers in Bangladesh
III. Investing in wine-producing grapes in southern Pakistan
IV. Investing in animal waste treatment facilities near industrial feedlots


I and II

II and III

I, II, and III

II, III, and IV

Answers

The answer is I, II and III.
A financial adviser would not recommend these three options because:
- Selling cattle to nomadic farmers in East Africa is a bad idea because they are very poor and can not afford to buy cattle, but instead reproduce the once they have, plus they only have enough cattle for their own needs, not big herds.
- Selling drought resistant seeds in Bangladesh makes no sense since the country has more than enough precipitation.
- Investing in wine producing grapes in southern Pakistan is not recommendable because in the period when the grapes are harvested there's intense rainfall caused by the monsoons, and also very often this region is flood in this period.

How is cotton farming harmful to the soil what was done to keep the earth usable?

Answers

The cotton farming is harmful to the soil because it is very easily infested by worms, and to keep the crops safe and healthy a big amount of pesticides are used. The big amount of pesticides are washed away with the water into the soil, the soil gets contaminated, and also the underground waters, and a big damage is done to the surrounding environment as well. Since it requires a lot of water for irrigation, also salinisation of the soil occurs, thus the soil is degrading. For this process to stop, in recent times the cotton farming has been directed in the way of the organic production, where there's no usage of toxic chemicals, but organic ones.
Answer:

Cotton plants require large quantities of nutrients and they absorb all the nutrients from the soil, what has been done to have the soil beneficial is cotton farmers ought started crop alternating.

Explanation:

Indeed if cotton farmers follow crop rotation because the pesticides and fertilizers do not endure on the plants themselves, they can influence later cotton crops, other food yields an area that may not relate to the cotton farmer at complete.

Strategies to improve water quality in the region include _____.
building dams
improving irrigation techniques

What do most current climate models suggest will happen to global temperatures by the end of the 21st century?

Answers

Current climate models base their operations on how much CO2 will be emitted in the future. Considering the actual trend, most models shows a rise in temperature in between 4/6 centigrade. Considerable change are possible with significace changes in the emission of co2.

ANSWER:

Most current climate models suggest that the global temperatures will rise by the end of 21st century.

EXPLANATION:

This will happen because of the global warming being caused by the greenhouse gas emissions. The rising temperatures will change the rate of precipitation which will increase because with more evaporation, the water cycle will become faster. The increased temperatures will also cause ice and snow to melt more resulting in the decrease in the glaciers and ice sheets that float on oceans. The climate will change in an extreme manner meaning that summers and winters will become more severe.

How does convection transfer heat from one place to another on the earth?

through the movement of winds and currents

through the movement of precipitation

through the angle of the sun’s rays

through the greenhouse effect

Answers

Thermal energy is transferred from hot places to cold places by convection. Convection occurs when warmer areas of a liquid or gas rise to cooler areas in the liquid or gas. Cooler liquid or gas then takes the place of the warmer areas which have risen higher. This results in a continous circulation pattern. Water boiling in a pan is a good example of these convection currents. Another good example of convection is in the atmosphere. The earth's surface is warmed by the sun, the warm air rises and cool air moves in.

Convection is the movement of heat through gases or liquids. Heat from the sun heats the air which can account for A and D, but a lot of the Earth's heat is distributed by the ocean. Water has a high specific heat which can absorb a lot of heat in one place, and distribute it in a colder place evening out the Earth's temperatures a bit.

So, the answer would be 
through the greenhouse effect
And could also be through the movement of winds and currents

How does trade and exchange affect groups of people? How does this relate to wealth in Brazil?

Answers

Trade and exchange mostly always benefits those nations that engage to it, nevertheless only when it is average to the total national economy. Also, a minority is always hurt by the evolution of trade patterns, and they’ll always ask for protection. In relation with this, Brazil is composed of a only a few wealthy people and a lot of very poor people. This gap among the highest and lowest socials levels is so huge, even though it already decreased during the late 1990s. However, stabilization to the economy, by means of lower inflation levels has likely added more purchasing power to the less fortunate.

How did southeast Asia’s physical geography encourage the cultivation of rice?

Answers

Southeast asian countries like Philippines, Thailand, and Vietnam are located near the equator. Thus, they only have wet and dry seasons (except for the northern parts of Vietnam). Climates in the tropics are the best for growing rice because it doesn’t get as much cold and freezing as winter. Also, Philippines and Indonesia have lots of islands, and more land that could be used as rice fields.

HELP!!!!!! FAST!!!! What role does the S-P interval play in locating an earthquake epicenter?

Answers

P and S waves travel at known velocities through the Earth. S waves are slower than P waves by a known amount. As the P and S waves travel out from an earthquake the P waves get progressively farther ahead of the S waves. Therefore, the farther a seismic recording station is from the earthquake epicenter the greater will be the difference in time of arrival between the P and S wave. The distance of a seismic station from an earthquake is easily determined from the S-P interval, the time difference between the time of arrival of the first P wave and the first S wave.
