Answer:
Convection currents flow due to variations in the temperature and salinity in seawater, both of which influence its density. Variations in density in different regions of the ocean will cause water to flow from less dense areas to more dense areas as water heats up and becomes less saline, producing a horizontal convection current. Vertical convection currents can arise as cooler, more saline water sinks, causing warmer, less saline water to rise.
<u>Answer</u>:
<em>Topographic maps are plan-see portrayals of Earth's three-dimensional surface. They are a standard kind of guide see that gives an overhead, or elevated, point of view. </em>
<u>Explanation</u>:
Among the characterizing <em>highlights of a topographic guide are the form lines that demonstrate areas of consistent height.</em>
The height interim between the shape lines is subject to the degree of detail gave by the <em>guide and the sort of geology present. </em>
For instance, areas with critical topographic variety may require shape lines isolated by 40-100 ft., <em>though by and large level lying districts with minimal topographic variety may have all the more comprehensively isolated 10-20 ft. forms.</em>
Answer:
Explanation: The only real solution is to have a large automated labor force moving materials from Venus to Mars to make Mars large enough to kick start it's own magnetosphere and natural life cycle processes. The solar winds could potentially be harnessed to travel back and forth while stripping materials from Venus to Mars.
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.
