What is the cause of Niagara Falls?
The formation of Niagara Falls is mainly attributed to the geological background and glaciation. During glacial periods, rocks and sand carried by glaciers impinge on river beds, forming canyons and laying the foundations for waterfalls. The water speeds up, the erosion increases, and the waterfall moves forward. Climatic conditions and human activities also have an impact on the formation and change of waterfalls.
Section 1 Geological Background
Located on the mighty Niagara River, Niagara Falls originates in New York State and flows through the United States and Canada.
This natural wonder was formed by the movement of the Earth's crust and the carving of glaciers billions of years ago.
The rocks on both sides of the waterfall have formed unique geomorphologic features after a long period of geological evolution.
The geological setting of Niagara Falls is not only breathtaking, but also a witness of natural history.
Section 1 Geological Background
This land, has a long history, its geological structure ever-changing, like a thick history books.
Glacier erosion, honed by the years, will be carved here landscape mix.
The texture of the rock and the layers of the soil reveal the antiquity and mystery of the land.
Section 1 Geological Background
During the Ice Age, glaciers melted and vast currents swept across the North American continent, creating deep canyons.
The river Pentium ceaselessly, scours out the landform miracle, the canyon magnificent, is breathtaking.
As the years passed, these great rivers changed the geography of the North American continent, leaving an eternal imprint.
Section 1 Geological Background
Niagara Falls originated from the unique geological structure of the land.
Hundreds of millions of years of wind and rain erosion, shaping the outline of the canyon.
The layers of rocks bear witness to the changes of the Earth.
Section 2 glacial erosion
During the Ice Age, huge glaciers carried large amounts of rock and sand, which cut and honed the Earth's surface to create a unique landscape.
Glaciers flow like giant bulldozers, carrying soil and debris along the way into the valley, forming rich sediments.
As the glaciers melted, these sediments gradually settled on the valley floor, creating fertile land that provided for later biodiversity.
The erosion of glaciers not only changes the shape of the Earth's surface, but also affects the Earth's climate and environment.
Section 2 glacial erosion
As the glacier moves, the material impinges on the riverbed and the riverbed is gradually eroded.
The riverbed is cut down to form a unique geomorphologic feature.
The erosion of glaciers has created a rich and colorful natural landscape.
Section 2 glacial erosion
The Niagara River bed was eroded by glaciers and gradually formed a canyon hundreds of meters deep.
The glaciers have made the river bed smooth, and the river is roaring in a deafening roar.
Years of baptism, so that the canyon on both sides of the rock weathering, forming a unique landscape.
Glacial erosion not only changed the riverbed, but also shaped the spectacular Niagara Falls.
Section 2 glacial erosion
Rocks on both sides of the canyon have long been under the action of glaciers, creating steep banks, and traces of time are carved into the rocks, telling old stories.
The huge force of the glacier, like a sword, cutting the mountain, creating a magnificent natural landscape.
Rock surface, ice cracks crisscross, witness the melting and change of glaciers, the passage of time in each crack reflected incisively and vividly.
The power of glacial erosion not only changes the landscape, but also breeds a unique ecosystem, and life survives tenaciously in extreme environments.
Standing on the edge of the canyon, overlooking the foot, that piece of glacier remains, people can not help but sigh the magic and greatness of nature.
Source and waterfall of Niagara River
The waters of Lake Niagara converge and meander through the canyon to form Niagara Falls.
The water on both sides of the waterfall accelerates, scouring the rocks and forming a magnificent landscape.
Torrent raging under the waterfall, driving the splash, magnificent.
The water swirls around the falls, creating unique swirls that are spectacular.
With its magnificent scenery, the Niagara River attracts tourists from all over the world.
Flow velocity and direction
The topography of the riverbed is changeable, and the water flow at the waterfall accelerates.
The rapids were rough and the speed was amazing.
The direction changes, sometimes turns left, sometimes turns right.
The water Pentium, making layers of spray.
Flow velocity and direction
The scouring force of the riverbed rock is enhanced obviously under the impact of the flow velocity.
This increased flow rate makes the river bed rock erosion process more intense.
The surface of the rock is gradually washed more smoothly by the rapid flow of water.
Continuous erosion leads to changes in the rock structure of the riverbed.
The rocks at the bottom of the river bed are constantly worn and shaped by the impact of water.
With the increase of flow velocity, the change of flow direction also affects the erosion process.
At the bend of the river, the flow velocity increases and the erosion effect is more obvious.
The riverbed rocks are constantly changing under the combined action of velocity and direction.
Waterfall, water droplets such as sword, across the sky, falling aroused layers of ripples, the surging water, like the long River of History, carrying the traces of time, All the way.
Years silent, the power of erosion, over time, so that the waterfall continue to move forward, its scale, breathtaking.
Water to, traces of mottled, witness the flow of time, the slowly flowing river, telling a section of unknown story.
The rocks under the waterfall are smoothed by the force of the current, as if whetted by time.
The climatic conditions in Niagara Falls are favorable for erosion, and the humid climate provides sufficient energy for water erosion.
Four distinct seasons, abundant rainfall, so that the rocks around the waterfall are constantly impacted.
Long water erosion, making the rock surface gradually peeling off, forming a unique landscape.
It is this climate that makes Niagara Falls one of the most spectacular waterfalls in the world.
The seasons change, the climate changes, the raindrop is like silk, moistens the earth.
The water flows away, scouring the riverbed, and the rock slowly changes shape as it dissolves.
The force of nature, silent, shaping every inch of the texture of this land.
Years of circulation, geomorphological changes, witnessed the blend of climate and erosion.
Section 4 Climate and Erosion
Niagara Falls, a world-famous wonder of water, has evolved over the years in shape and scale.
Over the long geological years, the rocks in the waterfall's riverbed have been buffeted and weathered by water, day after day, year after year.
It is this constant natural erosion that shapes the unique features of Niagara Falls and makes it a timeless landscape.
Section 5 Impact of Human Activities
Human activities have brought about significant changes in the erosion process of Niagara Falls.
The development of tourism around the waterfall and the influx of tourists have damaged the vegetation around the waterfall.
The frequent movement of ships has impacted the riverbed and accelerated the rate of erosion.
The pollution enters the river and affects the water quality of the waterfall.
Human development around waterfalls, such as buildings and road construction, has also had an impact on erosion processes.
The interaction between human activities and natural environment makes the erosion process of Niagara Falls more complicated.
Section 5 Impact of Human Activities
Riverbank construction and water conservancy projects stand like boulders, changing the direction and strength of the water, Subtle changes have taken place in the rate and shape of erosion.
Humans dug tunnels and built bridges on river banks, and these actions, like giant hands, quietly changed the landscape, and the outline of the waterfall was reshaped.
Water Conservancy project is like a sword, cutting the original track of the river, the form of the waterfall in the carving of human wisdom, gradually showing a new style.
Human activities, like the carving knife of time, have left deep imprints on the surface of nature, the erosion speed and form of waterfalls, Also at this moment was given a new definition.
Behind the splendor of Niagara Falls is the work of Mother Earth for countless years, during which the forces of nature have shaped the falls. Has given it an incomparable charm.
In the torrent of human activities, Niagara Falls has also encountered unprecedented challenges, since the Industrial Revolution, human development and use of natural resources, The ecological environment of the waterfall is under great pressure.
Human misconduct, such as overfishing, pollution and ecological destruction, is gradually changing the ecological balance around the waterfall, we must realize, Protect the environment, care waterfall, is our common responsibility.
