Seismologist Inge Lehmann, studied the seismic waves of an earthquake and discovered about inner core in the mantle layer of Earth. She States that there is a boundary of discontinuity between the outer and inner core of Earth.

She studied the travel of secondary and primary waves during an earthquake and how it flows at different shells of Earth's layer which helped her in finding about the inner core of mantle. She observed that the inner core is a solid layer inside the molten layer of outer core

Choose all of the areas in which the United States invoked the Roosevelt Corollary to the Monroe Doctrine.
LekaFEV [45]

The correct answer to this open question is the following.

Unfortunately, you did not attach the options to answer this question.

What we can do to help you is commenting on the following.

Throughout history, the United States invoked the Roosevelt Corollary to the Monroe Doctrine to accomplish some imperialistic and interventionists goals in different Central American and South American countries.

We can set some examples here. For instance, that was the case of the US intervention in the Island of Cuba, in Nicaragua, Dominican Republic, Hati, and the US presence for so many years in the Panama Canal.

Let's have in mind that the Roosevelt Corollary to the Monroe Doctrine was originally called for intervening in Latin American countries that could not pay their debt to European creditors.

The message the US wanted to convey to European superpowers that had interests in this region was that from now on, it was going to be the US business to intervene in the Americas. If Europe tried to intervene, it was going to be understood as direct aggression to the United States.
