Answer: 3.6 seconds
Explanation: Geologic time is a way of measuring time based on events in the history of the Earth. If we compress this into one year, a single geologic year equals 4.6 billion years because the planet was formed 4.6 billion years ago.
Columbus arrived in the New World in August 1492, 528 years ago.
If 4.6 billion years = 1 year in geologic time,
528 years = 528 X 
=3.6 seconds
<em>(I broke the year down into seconds by breaking it down into days, then hours, minutes and seconds because the value is very small)</em>
<em />
<em>So, if we compress geologic time into a single year, only 3.6 seconds have elapsed since Columbus arrived in the New World</em>

Answer:
Dentistry of gases and mass and distance from sun.
Explanation:
- Out of the 8 planets the earth is an only habitable planet in the solar system till date and thus is called as the blue planet as it has water as the source of life form.
- Other planets like the mars and Venus are likely that of the earth but have a certain amount of variation in their atmospheric composition and characteristics and thus they have different cycles.
- Thus like the variation of the sunlight in the earth equator and the poles, due to the more bulges to the equator areas and less of above.
- Similar is the variation in the gases and the density of the mass of the planets and other four-planet are gas giants and have there own atmosphere surrounded in thick layers.
It was a quarter of billion years ago and the world nearly came to an end. there was dinosaurs and the greens that they used to eat and today a dino's head is sculptured on a high cliff.
