Due to the rotation of the Earth, different cities on Earth experience different times of day at the same moment.
As Earth keeps rotating on its axis, the different locations of the Earth change position with respect to the Sun. The sunrise and sunset, day and night are caused by the course of a 24-hour rotation of the Earth and Sun. Around the clock, half of the Earth faces towards the sun while half faces away from it.
The half facing towards the Sun is brightened by the Sun's glow and it is daytime on that half. At the same time, half of Earth that is in darkness experiences nighttime.

Different cities on Earth experience different times of day at the same time due to the Earth's rotation.
On only one side of the Earth does the sun shine. There will be daylight on this side of the planet. The opposite side of the Earth from the Sun will experience night because of how the Earth rotates. The area of the Earth that is currently experiencing daylight will eventually experience night. Night and day alternate due to the Earth's rotation.
Since we discovered that the Earth's axis is tilted and that the equator does not always face the Sun directly, different parts of the planet would experience days and nights that are not always exactly 12 hours long.

What is NOT a reason that there are still poor nations in such an advanced world?
O the inability to sustain a growing population due to disease and/or famine
oppressive or unstable governments that limit a citizen's ability or desire to excel
O E-mail, the Internet, and cell phones have transformed the way in which people share ideas
Othere is a lack of natural resources to help a nation develop trade
The correct option is:
E-mail, the Internet, and cell phones have transformed the way in which people share ideas
Some key reasons why there are still poor nations in an otherwise advanced world:
O Oppressive or unstable governments that limit a citizen's ability or desire to excel
This limits economic and social progress. Poor leadership and governance hamper development.
O The inability to sustain a growing population due to disease and/or famine
This creates cycles of poverty, lack of healthcare, poor nutrition, disease - all of which sustain underdevelopment.
O Lack of natural resources to help a nation develop trade
Without resources, countries struggle to build industries, trade partners, and wealth.
E-mail, Internet and cell phones themselves do not necessarily transform a poor nation's economy or development levels. They are tools that can be utilized, but do not automatically cause broad-based improvements on their own. Technology needs to be coupled with other factors like governance, healthcare, education, resource access, etc. to help lift countries out of poverty.
So in summary, while technology can help in development, it is not enough on its own to substantively transform poor nations. Political, economic, social and resource-based challenges are bigger roadblocks.

In the 1950s, experts warned that the largest number of victims of a nuclear attack would die from the immediate effects of the blast and thermal radiation. The blast wave from a nuclear explosion can cause extensive damage to buildings and infrastructure, leading to a high number of fatalities and injuries. The thermal radiation released from the explosion can also cause severe burns and ignite fires, further adding to the destruction and loss of life.
In addition to the immediate effects, experts also warned about the long-term effects of a nuclear attack, including radiation sickness and long-term exposure to radiation. The radioactive fallout from a nuclear explosion can contaminate the environment, food and water sources, leading to widespread illness and death.
Overall, the threat of a nuclear attack was seen as a major concern during the 1950s, and experts worked to develop strategies to minimize the damage and loss of life in the event of such an attack. Today, the threat of nuclear war remains a concern, and efforts to reduce the risk of nuclear conflict and prevent the spread of nuclear weapons continue to be a focus of international diplomacy and policy-making.
While some believe that nuclear fallout may cost more lives, it all depends on the circumstances. However, the initial blast coupled with extreme radiation usually causes more deaths and fatalities.
Have a Great Day!
