Answer:
B. Warm Caribbean Sea waters were forced up into the north Atlantic Ocean
Explanation:
South America and North America were not connected until 10 million years ago, but instead they were separated by water, thus the Caribbean Sea was connected with the Pacific Ocean. Because of this, the warm waters from the Caribbean were not forced further north in the Atlantic, but instead they were moving between the two continents. Once the two continents merged though, the warm Caribbean waters were forced to move toward the north Atlantic, thus they started to move towards Europe. Because they were warm currents, they significantly warmed Europe, up to 10 C degrees more on average, significantly changing the climate in this part of the world.

∠ABD will be 40 degrees in the provided question.
<h3>Describe an angle.</h3>
When two rays or straight lines intersect at one of their ends, an angle is created. Vertex of an angle refers to the point at which two points meet. The Latin word "angulus," which means "corner," is the origin of the English term "angle."
An angle is a figure in Euclidean geometry made up of two rays that share a common terminal and are referred to as the angle's sides and vertices, respectively. Two rays can form angles in the plane where they are positioned. Angles are also produced when two planes intersect. These are referred to as dihedral angles.
In the given question,
As ∠ABC given = 85°
∠ABC= ∠ABD + ∠DBC
85° = 3x + 1 + 4x -7
85° = 7x - 6
X = 91/7 = 13
∠ABD = 3(13) + 1 = 40°
