What else can I help you with?
Which hypothesis states that continents slowly moved to their present-day positions on Earth Is it subduction or erosion or continental drift or seafloor spreading?
The hypothesis that states that continents slowly moved to their present-day positions on Earth is called continental drift. This theory was proposed by Alfred Wegener in the early 20th century, suggesting that continents were once part of a single supercontinent called Pangaea and have since drifted apart.
What role does continental drift play in erosion?
Continental drift plays a role in erosion by influencing the distribution of landmasses and the formation of topographic features. As continents move, they can create new mountain ranges, change the direction of river flow, and alter the patterns of erosion and sediment transport. These changes in topography can impact erosion rates and shape landscapes over long periods of time.
What forces control the shape of a continental shelf?
The shape of a continental shelf is mainly controlled by past and present geological processes, such as erosion, sedimentation, and tectonic activity. Sea level changes and climatic conditions can also influence the shape of a continental shelf by impacting erosion and sedimentation rates.
What is the erosional part of continental margin?
Erosion happens constantly everywhere, from mountains to seashores. Although I would imagine that the greatest amount of erosion would occur in water, so perhaps anywhere from a near shore enviroment down to the continental slope/abyssal plain.
Steep area between continental shelf and ocean floor?
The steep area between the continental shelf and the ocean floor is called the continental margin. A continental margin is usually composed of a steep continental slope that is followed by the flatter continental rise.

What is the major source of the dissolved minerals that affect the salinity of ocean water?
Continental Erosion
Most common way that material is added to a continental shelf?
Erosion and sediments from large rivers.
Who don't continental coastlines fit perfectly together now?
because of erosion over time.
What is a continental coast?
A continental coast is the boundary where a continent meets the ocean. It typically includes a variety of landforms such as cliffs, beaches, and headlands. Continental coasts are subject to processes like erosion, sediment transport, and tectonic activity.
What is the difference beween a hypothsis and a theory?
A hypothesis is any idea used to explain and test a scientific idea, while a theory is a hypothesis that has become scientifically accepted. For example, say I hypothesize that rocks in a stream are worn smooth by erosion. This is a hypothesis of sorts. I test this hypothesis by putting rocks in a room and in a stream, and conclude that the stream rocks have been worn smooth. If I complete multiple tests and the scientific community believes in my conclusion, I would call it the Theory of Water Erosion, or something similar.

The steep area between the continental shelf and the ocean floor is called the continental margin. A continental margin is usually composed of a steep continental slope that is followed by the flatter continental rise.
What forces control the shape of Continental slope?
The shape of the continental slope is primarily controlled by gravitational forces, erosion by currents and waves, and tectonic processes such as subsidence and uplift. These forces work together to shape the steep boundary between the continental shelf and the deep ocean floor.
How are Continental plateaus formed?
During continental drift, the Pangaea broke into, 2 parts: Gondwana land and Laurasia, they drifted apart and were raised up to form Continental plateaus. Eg: Canandian Shield, Deccan Plt, Plt of West Africa. Soham_Patha Bhavan
