Answer:
I believe the answer is C.
Explanation:
Southeast Asia is very prone to typhoons
Answer:
C. its age
Explanation:
Rex is most likely trying to figure out the age of the rock formation. It is usually done by comparing the isotopic ratios of the daughter to the parent and their decay rates.
- This is known as radiometric dating.
- Here an exact numerical age of the rock is usually obtained by measuring these isotopic ratio.
- The rate of decay serves as a clock to measure how far the radioactive material has decayed in time
It's a frozen wasteland. nothing can grow there. the conditions are to harsh to survive
Answer: Alaska has more land area than California
Explanation:
The seismic activity density of a region is the ratio of the number of earthquakes during a given period to the land area:
Seismic activity density = number of earthquakes/land area
If California has 103,718 mi2, and a seismic activity density of 0.0964, then:
density of 0.0964 = number of earthquakes/103,718 mi2
0.0964*103,718 = 9,998 earthquakes
If Alaska has 570,641 mi2, and a seismic activity of 0.0491, then:
density of 0.0491 = number of earthquakes/570,641 mi2
0.0491*570,641 = 28,018 earthquakes
Even though Alaska has a greater amount of earthquakes, California has a greater density, because it has less land.
The website with the URL .edu will be more credible because .com tends to be a commercial site while .edu is an educational site.
