Answer:
There are more earthquakes on the West coast of the United States, because the boundaries of the North American, Pacific, and Juan de Fuca tectonic plates are located there. As the edges of the plates slide past or are forced under each other, the movement creates earthquakes
Answer:
The correct answer is B.
Explanation:
Option A is wrong. Mammals were not the prominent species before the extinction of dinosaurs because the mammal species that lived during the dinosaurs' era were so small that they only weighed several grams and occupied small areas as their habitats.
Option C is wrong. As dinosaurs became extinct, reptiles and "birds" remained as their descendant which evolved to some of the species that we know today.
Option D is wrong. Pangea started to break up to form the geographic isolation for the diversion of many species around 175 million years ago.
So the correct answer is B. Massive extinction disrupts and changes the food chain in such a big way that it triggers a domino effect that leads to species adapting to their new environment and diversifying thus forming new species in the process.
I hope this answer helps.
<span>John can use Cladistic
Analysis as an approach to trace the classifications of the lion and cat
because he can trace a common ancestor for them due to the cat and the lion
having the same characteristics and traits. They are considered to be closely
related because they share a common ancestor which means that they are closely
connected. The earliest discovery of using this method was by Peter Chalmers
Mitchell in 1901 as he was studying how different types of birds belong to the
same ancestry.</span>
It is called a nucleus. It's what determines what type of metal, gas, or whatever on the table.
I think the correct answer from the choices listed above is the first option. THe tool that would be <span>useful for testing cleavage and fracture in a mineral would be a hammer. It can test how a mineral acts when subjected to a very large amount of pressure or force. Hope this answers the question.</span>
