Erosion and Other Stuffs Related
By Abby Incorporated 🌊🐳
The 3 primary forces that changes earth's surface are:
1.) Glaciers moving and pushing through mountains.
2.) Water (rain and floods) weathering down on land and stone.
3.) Natural disasters (like tornadoes and earthquakes) tearing up land.
🌋Volcanoes🌋
Volcanoes are mountains with stored lava and magma inside. Sometimes volcanoes, can be dormant and not be active. Meaning that it won't blow up and explode with lava and ash everywhere. But sometimes dormant volcanoes can become active once again and is ready to explode. When volcanoes are erupting, people have to evacuate and move to a safe place for months or maybe even years, for fear that their village or homes being destroyed by fire and ash. Volcanoes can also cause erosion and land to change formation and shape.
☁️Earthquakes☁️
Earthquakes are natural disasters that happen when the ground is shaking violently which is caused by the earths tectonic plates when they are shifting. Earthquakes usually occur or begin right near fault lines. Fault lines are made by shifting tectonic plates. Seismometers are tools to help measure
how big earthquakes are and how dangerous it is.
❄️Glaciers❄️
Glaciers are basically just big icebergs that are near Antarcticam Greenland, and the Canadian Arctic. Glaciers are made up of very and strongly compressed snow that has been staying in the same place for a long time. Presently, glaciers are about 10% of Earth's total land area. Glaciers used to (and still sometimes do) slowly move across the Earth and bring nutrients and good soils from the edge of river beds, or edges of oceans where the dirt is rich and extra fertile than some other dirt. Glaciers can be very slow or actually very fast. The fastest glacier ever was the Jakobshavn Glacier (formed in Greenland) which went so fast that it was went more than 10.5 miles per YEAR. But also, 150 feet a DAY. That is a pretty fast glacier!
☀️Glaciers With Global Warming☀️
Global warming has a big impact on glaciers. Especially traveling ones. They will melt (slowly) and since they are HUGE, it would probably cause floods on nearby cities or towns. What's worse is that all the big and important cities are right near the edge of the continent or country meaning, that glaciers can come at anytime and cause huge floods!
How Glaciers Move
They move depending on how much snow and ice that's on the glacier. If there's more ice and snow added on the glacier than lost, it will move forward. If more is lost than added, it will move back.
Also, if the glacier comes to a certain thickness and weight it will be so heavy that it will
change shape and (because of gravity) will move slowly. Thanks Gravity!!! 👍
Weathering and Erosion
Weathering is when a rock of some sort or just any surface gets worn away or eroded. Erosion is what it's called when something is weathering down something else. Like water or rocks can cause erosion. Wind and sand can cause erosion too! Sand is actually rock that has been eroded for many, many years (like more than a couple hundred years we're talking about).
Different Types Of Erosion/Weathering
There are many types of erosion or weathering. For example, chemical weathering. This is when water (works better if water is a little acidic) mixes or meets rock and keeps flowing to make cracks and little tunnels. There is also physical weathering which is sometimes called mechanical weathering, physical weathering is what it's called when rocks break apart without changing their chemical composition (BTW, chemical composition means different amounts of chemicals and minerals in types of rocks).
What Is Soil?
This is one of the questions I have to answer as a necessity to the presentation. So I'll make this short. Soil is just a fancier and more scientific name for dirt. :3
Deposition
Deposition (geologically) is the process which sediment, soil, and rocks are added to a landform or land mass. In deposition, wind and water lay down grains of eroded material that has been transported from another place. Deposition happens when the forces which transport sediments are weaker than the forces of particle weight and friction. This causes a resistance to movement and the particles drop down.
Eroded Landforms
Eroded landforms are landforms that have been eroded or weathered over time (I'm guessing you probably figured that though). They can carve caves and arches in mountains and cliffs. They are really beautiful and so landscape-y.
