Answer:
1. Today instead of rotating upright, The earth's axis is tilted 23.5 degrees. The angle varies a little over time, but the gravitational pull of the moon prevents it from shifting by more than a degree so. This tilt is what gives us seasons.
2.The cooling effects of more indirect sunlight cause autumn and winter. Because of the earth's approximately 23.5° tilt, the season in the northern and southern hemispheres reversed, about six months apart from each other.
Answer:
Because of climate change
Answer:
The fossil is 17,100 years old.
Explanation:
The decay equation:
Integrating both sides
When t=0, N=
= initial amount
The decay equation is
Given that,
The half life of carbon - 14 is 5700 years.
For half life, 
To find the value of 
, we need to put the value of N and t in the decay equation.
[ Divided both sides]
Taking ln both sides
[ 
]
[ln 1= 0]
The fossil has only 12.5% of the carbon carbon-14 that it would have had originally.
So, 
Then,
Taking ln both sides
The fossil is 17,100 years old.
