Answer:
a. plate tectonics
Explanation:
plate tectonic theory describe the fact that the earth is divided into different thick plates(crust) that moves slowly and change in sizes. This plates drift away from each other , slides past another or even collide with each other . The resulting movement of this plates brings about the uneven configuration of the earth crust. Some part of the earth are been subducted while some are uplifted resulting to mountain belts and hills. The plate tectonic idea was born out of the theory of continental drifting and seafloor spreading.
continental drifting talks about the movement of the continents on the earth surface . it is believe that the continents changes position in relation to one another. Sea floor spreading is the idea that the sea floor drift away from each other into two parts with the mid oceanic ridge forming the mid points . As you move away from the mid oceanic ridges the floor becomes increasingly older in age.
Generally, plate tectonic plays a major role on how the earth looks, the structures that are formed and the rocks formed.
Because the earth is a globe and has rounded sides, it couldnt be a straight line it'd always have to be rounded to fit the curvature
Answer:
Food production contributes to Climate change, eutrophication and acid rain, as well as the depletion of biodiversity.
Explanation:
Answer:
Continental drift in terms of plate tectonics.
Explanation:
- Continental drift is a theory given to explain the formation of various plates or slabs on the surface of the earth and the theory is evident in the form of Alfred Wegener as a geologist who through his research and discoveries and advanced knowledge gave the concept.
- Plates on which the landmasses and various features are made is not static as it looks and is more dynamic and was more destructive in the past as the formation of the earth during the 4.6 billion years ago the continental landmass underwent transformations and breakthrough happened as the split and rejoined and again joined to form what is seen today.
- These plates drifted in such ways that the landmasses formed various properties of the northern and southern hemispheres. Wegener gave evidence of Jigsaw fit puzzle, drifting of the climatic zones, spreading of the plants and animals located at the same continental borders.
- Moving of the plates under the action of gravity and wind speeds.
Oil and natural gas. Both are needed all of the time in our daily lives.
