A big air current from Equator is reaching Florida. How does this phenomenon affect Florida?
It transports warm air to Florida, creating a warm environment.
Continental drift describes one of the earliest ways geologists thought continents moved over time. This map displays an early "supercontinent," Pangea, which eventually moved to form the continents we know today.
Continental Drift represents

A landslide is defined as the movement of a mass of rock down a slope. Landslides denote direct influence of gravity, a classic morphological cause of landslides is erosion, or weakening of earth due to water, building a new landform at the mountain base by........

The rock cycle is a geologic cycle that describes how rocks change from igneous, metamorphic, and sedimentary types over time. It is driven by plate tectonics, water cycle, and other forces. What low confirms this process?
Law of conservation of mass

A contact force that resists motion between two surfaces in contact
slowing the object down
force acting in opposite direction of the object in motion
