negative impact of droughts on the economy of South Africa
Answer:
Declining agricultural production could lead to shortages of some food items like maize, wheat and some protein sources such as meat and eggs. This could, in turn, force South Africa to import more. Thirdly, a shortage of local produce could push up prices
The damaging consequences of droughts on South Africa's economy underscore the necessity of creating plans to lessen their effects, such as investing in water infrastructure and encouraging the cultivation of crops that are resistant to drought.
What are the negative effects of droughts?Drought can shorten the growing season and make it easier for insects and diseases to infest some crops. Low agricultural yields might result in increased food costs and scarcity, which could cause hunger. The health of livestock bred for food can also be impacted by drought.
Agriculture has a significant role in the economy of South Africa. Droughts can lower agricultural productivity, which lowers food output, raises food prices, and lowers export income. Droughts may have a negative effect on South Africa's natural environment and thus on the number of travellers there. This can result in less money coming in from tourism, which is a significant source of income for the nation.

Which happened before the Neolithic Revolution?
A. Economic specialization
O B. Hunting and gathering
O C. Stratification
O D. The rise of civilizations
Answer:
During the Paleolithic and Mesolithic periods before the Neolithic, when people lived by hunting and gathering rather than by agriculture, the data suggest that hunter-gatherers also made war.
Explanation:
hope this helps
Before the Neolithic revolution, people subsisted on hunting and gathering rather than cultivation. Option (b) is correct.
Some human populations totally abandoned their nomadic, hunter-gatherer way of life to start farming, marking the beginning of the Neolithic Era. It may have taken humans hundreds or even thousands of years to completely change their way of life from one in which they lived off of wild plants to one in which they kept little gardens and eventually cared for vast crop fields.
Earlier groups relied on the practice of scavenging animal leftovers that predators left behind before hunter-gatherer cultures emerged. Because they did not depend on agriculture, hunter-gatherers exploited mobility as a survival tactic.
Therefore, Option (b) is correct.

The theory of plate tectonics implies that Earth's crust is composed of many lithospheric
plates that are in gradual, but continuous movement. Which statement explains the
movement of these lithospheric plates?
A
The underlying mantle layer is molten where convection currents cause the
movement of the lithospheric plates.
B
Earth's magnetic polarity differences at the poles cause the movement of the
lithospheric plates.
The gravitational pull from both the Sun and the Moon cause the movement of
the lithospheric plates.
C
Earth's rotation on its axis and its revolution around the Sun cause the movement
of the lithospheric plates.
The reason why the lithospheric plates that compose the Earth's crust are constantly moving is A. The underlying mantle layer is molten where convection currents cause the movement of the lithospheric plates.
Why do plates move?The earth's crust is made up of lithospheric plates that rest on the mantle which is molten as a result of the high temperatures of the core.
Convection currents in the mantle result in the plates moving as the currents come up from the core to heat up the mantle.

How can we reduce the impact of global warming?
Answer:
there are many ways
Explanation:
For example, a way of decreasing the impact of global warming is utilizing renewable energy into daily lifestyle. This could be switching to solar energy for heating homes and water via solar panels because it consumes natural resources which is in this case the energy from the Sun rather than using things such as boilers which consume fossil fuels and results in releasing greenhouse gases into the atmosphere which only intensifies the deterioration of the environmental state.
can I get a brainliest answer? :)
It will take more than a single person to reduce the impact of global warming, but here are a few things you can do to help with your part:
Power your home with renewable energy such as solar panels, windmills, etcReduce how much water you waste. A lot of toilets use more water than is needed, for example.Buy more efficient light bulbs. This goes hand in hand with renewable power as well.Try to eat less meat. You do not need to go "fully vegetarian," but the creation of meat products creates a lot of greenhouse gasses. Reuse and recycle. If you can use something again, then do. If you cannot, try to recycle. You can recycle many things, most will have some kind of label.Define the term government
