South Africa's location makes it a key spot for renewable energy in the forms of wind, hydroelectric and solar, as it is on the peninsula of the continent it has access to many of these rich resources. There is also a great deal of industry in South Africa, particularly in the mining of metals, as one of the country's largest exports. This extraction uses huge amounts of energy in the process and most of this equipment used in the extraction pumps toxic gases and chemicals into the atmosphere, if SA uses more renewable energy sources, the levels of pollution will decrease.
Answer:
Wind erosion is a natural process that moves soil from one location to another by wind power. It can cause significant economic and environmental damage. Wind erosion can be caused by a light wind that rolls soil particles along the surface through to a strong wind that lifts a large volume of soil particles into the air to create dust storms.

Answer
Physical weathering weathering is is breaking breaking up up rocks rocks by by force, force, while while chemical weathering weathering involves involves chemical chemical processes.
Explanation:
- Physical weathering refers to the mechanical weathering that takes place due to the freezing and thawing go the rocks which are exposed to hot and cold temperatures of the day and night
- An example of physical weathering is the onion peel weathering of rocks.
- While chemical weathering is the weathering by addition of oxygen, water and carbon to rock minerals.
Cumulus cloud has the cauliflower structure
Answer:
Quartz is not pure in this rock.
Explanation:
When quartz shows effervescence in contact with an acid, it means that it is not in its pure state, but rather related to other substances that may be cementing the quartz. This effectiveness is caused by substances that do not react like quartz, such as calcite.
In this case, we can conclude that in relation to the calcium-rich rock shown in the question above, the calcium is not pure, but it is likely to be related to calcite, or other material that does not react to acid.
