Answer:

B and C

Explanation:

B. In a given rock sample, the amount of Silicon-32 isotopes gets divided in half about every 170yrs.

This is the concept of half-life. Half life is the time take for half of a radioactive isotope to disintegrate. The shorter the half life the faster the isotope disintegrates.

From the question, we were told that it would take 170yrs for half of the isotope of Silicon to disintegrate to Phosphorus. This is the half life.

C. The half life can be used to determine the amount of Si-32 that has decayed from the time closure temperature was reached.

The closure temperature is very important in radioactivity. It is the temperature at which a system has cooled and there is no resulting disintegration of parent and daughter isotopes.

From first order kinetics, we know that the rate at which radioactive elements decay at any time is directly proportional to the number of radioactive atoms present. A knowledge of the half life helps to figure out the number of atoms that has decayed in time.

How did Wegener use the reconstruction of climate belts on this map to justify continental
Nadya [2.5K]

Wegener was able to use  evidence from climate change  so as to be able to give support his theory in the sense that he used  explained that   an island in the Arctic Ocean do contains fossils of tropical plants.

Base on the theory that continents were once connected  help in explaining the glacial striations  however, if the  continents always occupied their present-day positions, it will be hard to explain pattern of glacial striations since the theory of continental drift theory is based on the rotation of the Earth.

<h3>What is Wegener  continental drift theory?</h3>

It should be noted that Wegener suggested that  rotation of the Earth that come as a result of how the continents  shift towards and apart from each other.

Lines of longitude measure distance from where, the equator or the prime meridian?
dusya [7]
<h2>Answer</h2>

These lines measure the distance of Prime Meridan

<h2>Explanation</h2>

Prime Meridian line divides the earth into two hemispheres as South hemisphere and North hemisphere. Lines of longitudes runs vertically on the globe as up to down to connect these north-south poles. These lines are used to measure the distance of East or West location from the prime meridian. These lines cross the equator at the right angle (90^{o}) also known as Greenwich Meridian.
