Answer:
time taken for 25% Phlebotinum and 75% Dilithium is 168 million years
Explanation:
radioactive isotope of Phlebotinum decays into Dilithium.
time taken to half life takes = 42 million years
half life means that the Phlebotinum is 50% and Dilithium is also 50%
and now it is given that Phlebotinum is 25% and Dilithium is 75%
hence this condition will come after two half lives.
for one half life it takes 42 million years
and for second half life time becomes 4 times of first half life
time for 25% Phlebotinum and 75% Dilithium is = 4 × 42
= 168 million years.
hence time taken for 25% Phlebotinum and 75% Dilithium is 168 million years
Abyssal plains are large, flat features that cover about one third of the planet.
<h3>What are Abyssal plains?</h3>
- The broad, flat, sediment-covered regions of the deep ocean floor are known as abyssal plains.
- They have a slope of less than one foot of height variation for every thousand feet of travel, making them the flattest, featureless places on Earth.
- When tectonic plates separate, magma rises and forms new crust, filling the space that was left between the plates.
- When sediments from the shoreline pass over the continental shelf, tumble down the continental slope, and deposit on top of the more recent oceanic crust, they create an abyssal plane.
