Most people in Botswana earn their living doing which of the following?
farming
tending livestock
working in diamond mines
working in construction
In Botswana, the majority of people earn their living by working in diamond mines, which are the main contributors to the country's export income and provide substantial employment.
The majority of people in Botswana earn their living by working in diamond mines. Botswana's economy is heavily reliant on the mining sector, particularly diamond mining, which has been the principal extraction activity that dominates the country's export income. While there is also a significant presence of agriculture and livestock tending, as well as a growing construction sector, none of these surpass the economic impact of diamond mining. Additionally, Botswana has seen the rise of its service sector and has a tourism market benefitting from attractions such as the Kalahari Desert and game reserves. The stability provided by uninterrupted civilian political leadership and progressive social policies has fostered an environment where the mining industry thrives, and, as a result, it employs a significant portion of the workforce, contributing to Botswana’s position as having the second highest standard of living in the region after South Africa.
Suppose a star has the same luminosity as our sun (3.8×1026watts) but is located at a distance of 20 light−years . what is its apparent brightness?
The apparent brightness is [tex]8.667\times{10^{-33}}{\text{ W/}}{{\text{m}}^{\text{2}}}[/tex]
Further Explanation:
The apparent brightness of a light source is measured by dividing luminosity with surface area of sphere with radius that is equal to the distance from source of light. The formula for calculating apparent brightness is:

C.They have moveable eyelids.
D. They are ectotherms.
99 POINTS
Answer:
The characteristic that is common to "all three groups of reptiles" is that they are all ectotherms.
Explanation:
Almost all the reptiles are referred to as 'ectotherms' because they are all cold-blooded. They adjust their body temperature according to the temperature of the surrounding. Reptiles like snakes do not have claws or eyelids. Moreover, not all reptiles protect their eggs. The "sea turtles" lay eggs on the seashores and go back to the seas. Thus, the only common characteristic among all the reptiles is that they are all ectotherms.Answer:

Match the labels with the symbol on the weather map
From the given weather map- H denotes High pressure areas.
- L denoted Low pressure areas.
What is atmospheric pressure?
A layer of gases known as the Earth's atmosphere envelops the globe. The atmosphere is continually being drawn toward the surface of Earth by gravity, despite it appearing as though these gases might just float away into space. A place on Earth experiences atmospheric pressure when our atmosphere pulls down on it with a certain amount of power.
The mass of the atmosphere at a given location and the air temperature are the two fundamental factors that affect atmospheric pressure. There is a lot of atmosphere above us and the weight is particularly heavy if we're at a low level, as in a valley. That indicates that the air pressure is higher at lower elevations and lower at higher elevations.
The atmosphere's water vapour may also alter atmospheric pressure. Huge amounts of water vapour in extremely humid air make it less dense and lighter than dry air. This is due to the fact that oxygen and nitrogen, the most prevalent gases in our atmosphere, are heavier than water molecules. Therefore, extremely dry air can result in high atmospheric pressure and very wet air can result in low atmospheric pressure.
What it means on the Weather Map?
A thick air mass that is often colder and drier than the surrounding air is known as a high pressure system. Less dense air masses that are often moister and warmer than the surrounding air make up low pressure systems.
Typically, regions with high atmospheric pressure also have good weather. Clouds and storms can arise as a result of low pressure systems. Normally, air moves from high-pressure zones to low-pressure zones.

Sustainability refers to using resources in a way that meets current needs without compromising future generations' ability to meet theirs. Conservation involves practices like recycling and solar power, and the Endangered Species Act is a law protecting endangered species. Both concepts emphasize the interconnectedness of humans and the environment.
Explanation:
Sustainability is defined as the use of a natural resource in a way that meets the needs of the present and also preserves the resource for use by future generations. Conservation exemplifies sustainability through practices like recycling and utilizing renewable energy sources such as solar power. The Endangered Species Act is a legal framework designed to protect threatened and endangered animal populations by law.Examples of renewable resources include sunlight and wind, which are not depleted when used, thereby providing a sustainable source of energy. Sustainable practices in resource use, such as harvesting wood and cork in a way that does not prevent future generations from meeting their needs, directly support the health of ecosystems—the benefits of which humans are intricately connected to.
Conservation efforts often include establishing protected areas to maintain biodiversity and provide opportunities to appreciate nature with minimal impact. These efforts form an integral part of a sustainable ethic, emphasizing the interconnectedness of humans and nature and the necessity to practice environmental stewardship to ensure long-term availability of resources.
How many hours of daylight does New York State experience on the spring equinox?
On the spring equinox, New York State experiences roughly 12 hours of daylight and 12 hours of night.
On the spring equinox, every location on Earth, including New York State, experiences roughly 12 hours of daylight and 12 hours of night. This occurs on approximately March 21st and is due to the Earth's axial tilt, which is perpendicular to the line between the Earth and the Sun on this date. Hence, the circle of illumination cuts all latitudes in half, giving equal hours of day and night.
Interestingly, the actual day length on the spring equinox is slightly longer than 12 hours for all places on Earth. This is due to the way sunlight refracts in the Earth's atmosphere and the finite size of the solar disk.
