Answer:
The moons gravitational force at different points on the earth
Explanation:
The perstubation force of the sun on the moon at two places in its orbit . The blue arrows represent the direction and magnitude of the gravitational force on the Earth. Applying this to both the Earth's and the Moon's position does not disturb the positions relative to each other. When it is subtracted from the force on the Moon (black arrows), what is left is the perturbing force (red arrows) on the Moon relative to the Earth. Because the perturbing force is different in direction and magnitude on opposite sides of the orbit, it produces a change in the shape of the orbit.
In astronomy , perturbation is the complex motion of a massive body subject to forces other than the
gravitational attraction of a single other
massive body .

Because geologic evidence supported the existence of tropical swamps in the Northern Hemisphere
Subtropical / tropical wetlands are wetlands found along the coasts of subtropical or tropical regions. The Everglades in Florida, for example, is a well-known example of subtropical wetlands. These wetlands are often, but not always, dominated by mangrove trees. The
Northern Hemisphere includes North America, northern South America, Europe, the northern two-thirds of Africa, and much of Asia. The Southern Hemisphere includes most of South America, Africa, Australia, one-third of Antarctica, and some Asian islands.
The Northern Hemisphere refers to half of the planets north of the equator, and the Southern Hemisphere includes all planets south of the equator. Some continents pass through both hemispheres, but Europe and North America are all in the northern hemisphere.
