Answer:
Americans had played an active role in the economy and politics of cuba.
Explanation:
Before the 1959 United States and Cuba they have a good relationship. The rise of General Fulgencio Batista in the 1930s to the de facto leadership and presidency during two legislatures (1940-44 and 1952-59) produced a period of close cooperation between the governments of Cuba and the United States. The second term as President of Batista was initiated by a planned military coup in Florida, and US President Harry Truman soon recognized Batista's return to power with military and economic aid. When Fidel Castro came to power in 1959, relations between the two countries quickly devolved into bitter arguments, political grandstanding and the occasional international crisis.
Weathering is the process that wears down rock formations. Mechanical weathering occurs when rocks are chipped away or broken such as if water seeps into a crack and freezes thereby expanding and breaking the rock apart. Chemical weathering can occur when the chemical composition of a rock or mineral is disrupted. For example, rainwater mixing with limestone leads to chemical weathering
Erosion, on the other hand, occurs when pieces or rock or sand are blown about or get caught in river currents and are brushed against other rocks (leading to mechanical weathering).
