Half-life is defined
as the time which is taken to reduce the initial amount of isotopes by half.
Hence, after one half-life,
half of initial amount of isotopes will remain.

<span>The equation for the
half-life, t1/2 = ln 2 / </span>λ,<span> where </span>λ <span>is the decay constant. </span>

Explanation:
Earth is the only planet in the solar system with an atmosphere that
can sustain life. The blanket of gases not only contains the air that we
breathe but also protects us from the blasts of heat and radiation
emanating from the sun. It warms the planet by day and cools it at
night.
Earth's atmosphere is about 300 miles (480 kilometers) thick, but most
of it is within 10 miles (16 km) the surface. Air pressure decreases
with altitude. At sea level, air pressure is about 14.7 pounds per
square inch (1 kilogram per square centimeter). At 10,000 feet (3 km),
the air pressure is 10 pounds per square inch (0.7 kg per square cm).
There is also less oxygen to breathe.
If it were to be in a different position, life can no longer be alive on Earth.
Hoped I helped!
