Answer:
The BERING STRAIT Hypothesis states that Native people entered the Americas by crossing a land bridge between Asia and North America.
Answer: Mantle plumes, Continental rifts, island arcs, and Continental arcs
Explanation:
Mantle plume is the mechanism of convecting abnormally hot rocks within the Earth's mantle. The plume head partly melts on reaching shallow depths, the plume is often invoked as the cause of volcanic hotspots.
Continental rift refers to the belt of the continental lithosphere where the extensional deformation (rifting) is taking place. Continental rift zones have important consequences and geological features, and if the rifting is successful, leads to the formation of new ocean basins.
Island arcs are long chains of active volcanoes with intense seismic activity found along convergent tectonic plate boundaries. Most island arcs originate on oceanic crust and have resulted from the descent of the lithosphere into the mantle along the subduction zone. They are the principal way by which continental growth is achieved.
Continental arc is a type of volcanic arc occurring as an "arc-shape" topographic high region along a continental margin. The continental arc is formed where two tectonic plates meet, and where one plate has continental crust and the other plate has an oceanic crust along the line of plate convergence, and a subduction zone develops.
Answer:
It's an Angular Unconformity.
Explanation:
How old the rock is
thats my answer
The first question is D. desert
and the second answer is B. the study of land
because geography's meaning is the study of the physical features of the earth and its atmosphere, and of human activity as it affects and is affected by these, including the distribution of populations and resources, land use, and industries. HOPE THIS HELPS
