What happens during coal formation after plants die and fall to the bottom of a swamp.
Answer:
Coal is formed when dead plant matter decays into peat and is converted into coal by the heat and pressure of deep burial over millions of years.
Explanation:
When plants die, they are no longer in contact with the air. The pressure of rocks and the earth makes the plant matter undergo a chemical change witch transforms the plant matter into coal. The process takes millions of years. This is one of the reason why coal is a non-renewable natural resource.

Why different places have different time zones?
What's the time in your country right now?
time zones are just what they sound like, in certain areas, in one spot it might be 12:00am in the next time zone, it would be 1:00am
the reason there different time zones is because on one side of the world it's day, on the other side, it's night.
for example in Pacific time zone compared to the China standard time, china standard time is +13 hours ahead of a place like California, if that makes sense.
where I'm at it is 1:30am

Within saprolite, spheroidal weathering often creates rounded boulders, known as cornerstones or woolsack, of relatively unweathered rock. Spheroidal weathering is also called onion skin weathering, concentric weathering, spherical weathering, or woolsack weathering. Because of their lightweight shapes, they remain in the same place.
How does spheroidal weathering occur?Spheroidal weathering is also a process of cracking and splitting off curved layers from a generally spherical boulder but on a much smaller scale. It occurs when a rectangular block is weathered from three sides at the corners and from two sides along its edges.

Would you give up quality of life for a higher standard of living?
Answer:
no
Explanation:
Imagine you heard the meteorologist on TV announce that the atmospheric pressure for the day is going to be 767 mmHg. You know that 1 atmosphere of pressure = 760 mmHg. So, based on the surface pressure map of the United States that you just created, which region (northern, southern, eastern, western, central) of the country might you be living in where the pressure is 767 mmHg?
Answer:
Southern
Explanation:
I think because that is closest to the sea level and as you go higher in terrain height pressure increases.
The region of the country the individual might be living in is the Southern part.
What is Pressure?
This is defined as the force per unit area of an object and is measured in mmHg or torr.
Increase in altitude leads to a corresponding increase in pressure which is why the individual was most likely closest to the sea level which is the Southern region.

Do you feel that the role of women has changed significantly to where they are now able to affect more cultural change?
Answer:
Women today are more prone to be included in paid work, for more prominent times of their lives. What has changed is the part of regular lady workers in the spot where they have aggregate force. The changed role opens up the possibility of liberation.
Explanation:
The role of women has indeed changed significantly in many societies, with women now having greater opportunities to affect cultural change than in the past. In many cultures, women have traditionally been relegated to the domestic sphere, with limited access to education, employment, and political power.
Why is a role of a woman important in society?Women are remembered primarily in ways that support their well-being. They are producing a source of money to support the way of life. When they are employed in the teaching profession, they also contribute to society's protection, spread information, and increase public awareness.
The changing role of women is increased access to education. As more girls and women have been able to attend school and pursue higher education, they have gained the skills and knowledge needed to participate more fully in society. This has led to greater representation of women in fields such as science, politics, and business, and has allowed women to bring their perspectives and expertise to bear on issues of cultural importance.
