Answer:
A good answer should contain the following:
viscoelastic
Isostatic equilibrium
asthenosphere
This theory explains how the tectonic plates in the lithosphere can move freely on the asthenosphere. The lithosphere is less dense than the asthenosphere. There's an equilibrium of the buoyancy between the lithosphere and asthenosphere.
Explanation:
Tycho Brache is the person who suggested the sun and moon to orbit the Earth. Danish Nobleman is the person suggested the rest of the planets orbited the sun.
The percentage of the orignal uranium that remains after two half-lives is 25%
<h3>Data obtained from the question </h3>
- Original amount (N₀) = 100%
- Number of half lives (n) = 2
- Percentage remainig (N) =?
<h3>How to determine the percentage remaining</h3>
N = N₀ / 2ⁿ
N = 100 / 2²
N = 100 / 4
N = 25%
Thus 25% of the original sample remains

Answer:
C
Explanation:
Breaks are called faults, and the 2 tectonic plates at the fault move and they can squeeze together to form a mountain. They can also form earth quakes like that. Volcanoes can be formed by 2 tectonic plates that move apart
