A globular cluster is a collection of stars in the form of a sphere that orbits a galactic core. Global clusters are generally tightly bound by gravity, making the stellar density higher toward the center, and giving them their spherical shapes. Globular clusters are usually found in the halo of a galaxy.
The fact that the gravitational pull of a globular cluster is rather weak means that a single supernova explosion can blow the interstellar gas out of a globular cluster. This would mean that the gas left is not dense enough to form new stars. After the first generation, globular clusters cease to form new stars because they lack material due to their deficiency in heavy elements.
Answer:
d. clear evidence of land bridges, like the one connecting Alaska and eastern Russia, clearly exist and explain most of Wegner's observations without Continental Drift.
Explanation:
The correct answer for the given question is d. clear evidence of land bridges, like the one connecting Alaska and eastern Russia, clearly exist and explain most of Wegner's observations without Continental Drift.
The main objection to Wegener's hypothesis was his inability to identify a credible mechanism for continental drift.
Harold Jeffery pointed out that Wegener's proposition of the gravitational forces was not correct and that instead of breaking up land it would have brought Earth's rotation to halt in a matter of years.

The United States are divided into few large regions. Even though they may not always correspond with the actual geographic position of the state and its regional location as in south, northeast, west, or Midwest, the states are carefully put into the regional divisions, and it is mostly done by natural characteristics of the places, as well as climate.
