A thermally-driven circulation develops because: Group of answer choices in cold, dense air, isobars bunch closer together, while in adjacent warm, less dense air, they spread farther apart. aloft, high pressure develops in cold air regions while low pressure develops in warm air regions. at the surface, high pressure develops in warm air regions while low pressure develops in cold air regions. cold air rises and warm air sinks.
Answer:
Aloft high pressure develops in cold air regions while low pressure develops in warm air regions
Explanation:
A thermally-driven circulation, or thermals are the movement of warm air that move to a higher level due to the buoyancy forces acting on them. That is due to the difference in densities between the warmed and cool air
Given that pressure = Density, ρ × Gravity, g × Height, h, we have that decrease in pressure (low pressure) is due to low density, therefore, the warm air having low pressure, moves upwards, due to their low density
Therefore, the best option is aloft, (as we move higher), high pressure develops in cold air regions while low pressure develops in warm air regions

Lakes can form:_______.
a. when soil becomes supersaturated
b. during hurricane activity
c. because of a collapsed volcanic caldera or subsidence caused by rifting
d. as a result of the deposition of valley walls or subsidence caused by convergence.
Answer:
D
Explanation:
Idrk know how to explain this but um basically deposition of valley walls will create a river-like path which over the years creates a river I think. I just used process of elimination tbh... Hurricanes don't make rivers so B definetley isn't the correct answer. A collapsed volcanic caldera has legit nothing to do with rivers so thats a no for C. and that leaves A and D and if you poor like 100 whole jugs of water into soil its not going to create a river which leaves B as the only answer that makes sense. (I hope this somewhat helps, if need be I can try to elaborate more in the comments)
Lakes can form as a result of the deposition of valley walls or subsidence caused by convergence. Option d is correct.
What is lake?A lake is a body of water bordered on all sides by land. In the world, there are millions of lakes.

if 73.87% of South Africa's households use electricity for cooking. what do the remaining 26% use? suggest other three resources
Answer:
Africa’s population is among the fastest growing and youngest in the world. One-in-two people added to the world population between today and 2040 are set to be African, and the continent becomes the world’s most populous region by 2023, overtaking China and India.
More than half a billion people are added to Africa’s urban population by 2040, much higher than the growth seen in China’s urban population in the two decades of China’s economic and energy boom. How Africa meets its growing energy needs is crucial for the continent’s economic and energy future, as well as for global trends.
Growing urban populations mean rapid growth in energy demand for industrial production, cooling and mobility. With the growing appetite for modern and efficient energy sources, Africa also emerges as a major force in global oil and gas markets. The projected growth in oil demand is higher than that of China and second only to that of India as the size of the car fleet more than doubles (the bulk of which have low fuel efficiency) and liquefied petroleum gas (LPG) is increasingly used for clean cooking. Africa’s growing weight is also felt in natural gas markets as the continent becomes the third-largest source of global gas demand growth over the same period.

Which statement describes the Richter scale
According to the question, Richter Scale gauges fault movement during an earthquake. Therefore Option A is correct.
What is Richter Scale?
American seismologists Charles F. Richter and Beno Gutenberg invented the Richter scale (ML), a numerical indicator of an earthquake's size, in 1935. The height of the most significant seismic wave, as measured by the logarithm of its amplitude (height), is used to calculate the earthquake's magnitude.
Given that the Richter scale is logarithmic, whole-number leaps represent a tenfold increase. The rise in this instance is in wave amplitude.
In other words, a level 6 earthquake has a wave amplitude that is 10 times bigger than a level 5 earthquake, and between a level 7 earthquake and a level 9 earthquake, the amplitude increases by 100 times. Between whole number values, the energy emitted increases 31.7 times.
Hence, Richter Scale gauges fault movement during an earthquake.

Surface features that are created when water dissolves limestone, like sinkholes and disappearing streams, are parts of Group of answer choices a potentiometric surface. a geothermal landscape. a karst landscape. an artesian surface.
Answer:
The correct answer is ''a karst landscape.''
Explanation:
A karst landscape is due to the erosion of water in limestone, that is, it is the surface of the earth resulting from the action of water on soluble rocks, in a slow dissolution process that takes thousands and even millions of years –approximately 5 mm of advance in the rock every hundred years–. The phenomenon is common in limestone rocks. This type of relief originated from the dragging or accumulation of soluble and disintegrated materials, such as those made up of carbonates. Limestone rock can decompose with water, since it is soluble; this solubility increases with the presence of acids produced by the mixture of CO2 and water, or by organic acids from the microbial activity of the soil. In this way, the limestone rocks fragment and form holes that, over time, give rise to various types and sizes of holes or depressions on the surface.

In the past century, the world has recorded a rapid increase and decrease in population in different geographical areas. This has been influenced by different factors such as urbanization and family planning.
Urbanization creates better employment opportunities and wages. It also provides better social amenities such as schools and hospitals. These encourage people to move from rural areas to urban areas in search of a better living. The migration results in a decrease of population is the rural areas and a rapid increase in population in the urban cities.
Increased access to contraceptives has enabled women to limit family sizes. Women are able to plan for the number of children they intend to have. This has generally decreased the population growth in developed regions.

If an earthquake measures 1.5 on the Richter Scale, what is the intensity of this earthquake, relative to a 0-level earthquake? Round off your answer to the nearest integer.
Answer:
Intensity depends on the distance form the ground and source of energy.
Explanation:
Earth quake that has an intensity of 1.5 on the Richter scale can be detected only through the seismograph. The earthquake with an intensity of 0 levels on the Richter scale that is below micro will not be felt or rarely felt in scale. This can be defied by the Richter scale formula of R=log(IcIn), Ic is the intensity and In is the intensity if the standards earthquake. Hence the difference will be R2−R1=log(I2I1)Give one example of how the T (technology) variable could potentially increase the total impact of the United States, and one example of how it could potentially decrease the U.S. impact.
