What is the cause of the formation of Miyamoto Strait?
Miyamoto Strait is located between Honshu Island and Hokkaido Island, Japan, is an important shipping channel along the northern coast of Japan. Its formation is closely related to geological structure, plate movement, seawater erosion and sedimentation. Long-term plate movement and seawater erosion caused the crust to break, seawater intrusion formed the strait, coastal rock erosion formed marine erosion landform, Current and wave sediments form sandbars and shoals. Meanwhile, human activities such as the development of shipping and fishery have also led to some changes in the ecological environment.
The geographical position and general situation of Miyamoto Strait
The Miyamoto Strait lies between Honshu and Hokkaido, Japan, and acts as a bridge between the Sea of Japan and the Pacific Ocean.
The area is not only a hub for traffic between the two places, but also a busy channel for many ships.
Geographically, Miyamoto Strait has become an indispensable part of world shipping because of its unique position and strategic significance.
The geographical position and general situation of Miyamoto Strait
Strait length of about 100 twists and turns, beautiful scenery along the way, the narrowest point only 3.3 like a natural barrier.
Superior geographical location, connecting the two continents, has important strategic significance.
Economic value is inestimable, is an important channel of trade between the two countries.
The geographical position and general situation of Miyamoto Strait
Miyamoto Strait is located in the northeast of the Japanese islands, this area is the link between northeastern Japan and Hokkaido.
As an important shipping channel along the northern coast of Japan, Miyamoto Strait plays a key role in regional economy and transportation.
The sea area around the strait is rich in marine resources and is an important fishing base of Japan.
Geological structure and plate movement
Miyamoto Strait is located at the junction of plates, and its formation process is complex and subtle.
The changes of the Earth's crust and the movement of plates have shaped the unique landforms of the Miyamoto Strait.
The fracture of the Earth's crust is the trace of plate movement.
The evolution of geological structure has witnessed the interaction between plates.
Geological structure and plate movement
The Pacific Plate and the Eurasian Plate intersection, the crustal activity is frequent.
The interaction between the plates causes the Earth's crust to rise, creating magnificent mountains.
The fault zone is expanding and the geological morphology changes with each passing day.
The plate movement has shaped the unique landform and become a valuable place to study geological changes.
Geological structure and plate movement
Plate movement under the continuous fission of the crust, the gradual emergence of fault zones, the influx of waves.
Fault zone continues to expand, the emergence of a new strait above the sea, communication between the two sides.
Plate movement, the continuous evolution of the strait landscape, witnessed the vicissitudes of the Earth.
Seawater erosion and sedimentation
The force of sea erosion is like the carving knife of time, carving the outline of Miyamoto Strait.
Sedimentation is like a delicate picture, slowly laying out the changes in this area.
The interweaving of the two together depicts the unique geological picture of the Miyamoto Strait.
Seawater erosion and sedimentation
The rocks along the strait were gradually eroded by the sea under the baptism of time.
Sea caves, like the mark of time, bear witness to the power of the sea.
The sea platform is like a stage of nature, showing the spectacular geological changes.
Seawater erosion and sedimentation
The powerful forces of currents and waves, like invisible hands, carry sediments deep into the strait, where they are gradually deposited on the ocean floor.
As sediment accumulates, sandbars and shoals form on the ocean floor, where they lie quietly like islands on the ocean floor.
The sediment not only shapes the topography of the seabed, but also provides a habitat for marine life, forming a unique seabed ecosystem.
The carrying function of current and wave is the magic power of nature. They weave magnificent pictures on the bottom of the sea.
Section 4 Impact of Human Activities
The pace of human activities in the Miyamoto Strait this ancient land left a deep trace.
Ship shuttle, cargo loading and unloading, has brought prosperity, but also brought marine pollution and ecological destruction.
Smoke from factory chimneys on the shore drifted in the sea breeze, affecting the air quality in the area.
The unremitting efforts of humanity have left a unique mark on the land of Miyamoto Strait.
Section 4 Impact of Human Activities
Shipping waves frequently cross the strait, fishing vessels shuttle among them, the growing human dependence on these waters.
With the increase of activities, the ecological environment of the strait has changed quietly, and the living space of some species has been compressed.
Ship exhaust and fishing net residue, like a ghost lurking in the water, affecting biodiversity.
Water pollution and overfishing, so that this once marine paradise is no longer quiet.
Section 4 Impact of Human Activities
The plane's flight path cut through the blue sky, and the exhaust gas formed a trail in the clouds, virtually interfering with the migration of high-altitude organisms.
Smoke from factory chimneys obscures the sun's rays, affecting plants and animals that depend on it for survival.
Harmful substances in automobile exhaust are in the air, and the number of patients with respiratory diseases is increasing year by year.
The misuse of agricultural fertilizers and pesticides has led to poor water quality in rivers and lakes and serious destruction of aquatic habitats.
Overfishing has led to the depletion of marine resources, some rare marine life endangered.
Urbanization has accelerated, forests have been reduced and biodiversity is threatened.
Industrial wastewater is discharged directly without treatment, which pollutes underground water and affects human health.
Plastic waste piles up in the ocean, killing seabirds and sea creatures.
Human activities have an increasingly serious impact on the Earth, so it is urgent to protect the environment.
