The Earth's tilt is causing change of seasons on the latitudes north and south from 23 degrees, mostly being manifested in four different seasons.
Explanation:
The tilt of the Earth is a major factor that contributes to the occurrence of seasons in some parts of the planet. The tilt is roughly 23 degrees, and it half of the year it makes the Northern Hemisphere to be more exposed to the Sun, while in other half of the year it makes the Southern Hemisphere to be more exposed to the Sun. This results in changes of seasons throughout the year.
When the Northern Hemisphere is tilted toward the Sun, it experiences summer. During the summer, the North Pole experiences constant daylight because it is constantly exposed to sunlight. When the Northern Hemisphere is tilted away from the Sun, then it experiences winter, and the North Pole has constant night because it is to exposed to the Sun at all.
The transitional period between the winter and the summer is the spring, where the sunlight and temperatures gradually increase. The transitional period between the summer and the winter is the autumn, where the sunlight and temperatures gradually decrease. This is the same on the Southern Hemisphere as well, just in the opposite part of the year.
There are four stages that mark the seasons:
- spring equinox
- summer solstice
- autumn equinox
- winter solstice

It could be argued that the whites became more accepting of tehe civil rights of blacks because the government gave them little choice.

A radioactive element with a half-life of 1,000 years, and starting mass of 20 grams, will need 2,000 years to decrease to 5 grams.
Explanation:
The radioactive elements all have a specific half-life. Each element's half-life is well known, and they are used by scientists of numerous fields as they are excellent for determining the age of a particular item, be it or organic or non-organic nature. In this case, we have a radioactive element with a half-life of 1,000 years, and starting mass of 20 grams.
The half-life basically means that half of the mass of an element is lost during a particular period of time. For the element in question we need to find out how much time will be needed for it to decrease to 5 grams. In order to get to the result, we just need to add 1,000 years on every decrease of half of the mass:
20/2 = 10
10/2 = 5
So in 1,000 years, the element in question will decrease to 10 grams, and in further 1,000 years (2,000 cumulatively) it will decrease to 5 grams.
