South Africa has a republican government system, with a mixed market economy, composed of private liberty and a centrally planned economy.
<h3 /><h3>What is a planned economy?</h3>
It corresponds to the economic system where most companies belong to the state, which is responsible for decisions that influence business and the economy, unlike the market economy, which is determined by supply and demand.
Therefore, the centralized economy is an important factor in the country, where the state manages most of the wealth produced, with greater control over the economy.

Answer and Explanation:
In case, the major ocean currents stops or slows down, the heat distribution on the Earth will be affected in the following ways:
- There would be quite significant climatic changes.
- It affects one of the major phenomena in the ocean , the thermohaline circulation of the ocean which is responsible for the supply of heat to the polar areas.
- Heat distribution is affected in such a way that keeps the warm water of the equatorial region remains in the same region and can not delivered to the polar areas.
- This phenomena results in more heat in the equatorial region and colder polar areas.

Explanation:
the warming trend over the last 50 years (about 0.13° C or 0.23° F per decade) is nearly twice that for the last 100 years. The average amount of water vapor in the atmosphere has increased since at least the 1980s over land and ocean. and one more
If the world temperature rises by two degrees, mountain glaciers and rivers will start to disappear and mountainous regions will see more landslides, as the permafrost that held them together melts away. By 2100, sea levels could rise by a meter, displacing 10% of the world's population.
Global warming is projected to have a number of effects on the oceans. Ongoing effects include rising sea levels due to thermal expansion and melting of glaciers and ice sheets, and warming of the ocean surface, leading to increased temperature stratification.
<h2>Answer: D. Rayleigh wave
</h2>
Rayleigh waves are a type of surface acoustic wave that causes particles on the surface of solids to travel along an elliptical path in the vertical plane that contains the direction of wave propagation.
These waves include longitudinal (P wave) and transverse (S wave) movements whose amplitude decreases exponentially as the distance from the surface increases.
This means Rayleigh waves are generated by the interference between the P and S waves on the surface of the Earth.
