Rivers – weathering, erosion, and deposition

Your students will learn about erosion, how it affects the earth, and why it is so powerful in this series of games. According to study, the Weathering and Erosion learning goal, which is focused on NGSS and state requirements, improves student participation and academic success in your classroom.
Aside from plate tectonics, the most important change to the earth’s crust is caused by moving water (including ice). Wind causes water to move, resulting in waves. Water is often moved by gravity, which allows it to flow downward. The more water there is and the faster it flows, the more erosive effect it has.
Rainwater and runoff, above- and below-ground streams and rivers, ice sheets and glaciers, and oceans are only a few examples of flowing water. Both of them have an effect on the earth’s solid surface over the course of minutes, months, or millions of years.
Weathering is the mechanism of non-moving rock breaking down. When water freezes in holes in the rock, it spreads and fractures the rock, causing physical weathering. Water reacts with minerals in the rock to form new minerals and dissolve others, resulting in chemical weathering.

Weathering is the breakdown or dissolution of rocks and minerals on the Earth’s surface. Water, ice, acids, salts, plants, animals, and temperature variations are all weathering agents.
After a rock has been broken down, erosion transports the rock and mineral fragments further. There is no rock on the planet that is strong enough to withstand the effects of weathering and erosion. These processes carved landmarks in the United States, such as the Grand Canyon in Arizona. This huge canyon stretches for 446 kilometers (277 miles), is as wide as 29 kilometers (18 miles), and reaches a depth of 1,600 meters (1 mile).
The rugged terrain of Earth is continually shifting due to weathering and erosion. Over time, weathering wears away at exposed surfaces. The amount of time a rock has been exposed to the elements influences how prone it is to weathering. Rocks that are easily buried under other rocks, such as lavas, are less susceptible to weathering and erosion than rocks exposed to agents like wind and water.
Weathering is also the first step in the formation of soils because it smooths rough, sharp rock surfaces. Plants, animal bones, fungi, bacteria, and other species combine with weathered minerals. Weathered materials from a range of rocks are richer in mineral diversity and contribute to more fertile soil than weathered materials from a single type of weathered rock. Glacial till, loess, and alluvial sediments are some of the soil forms associated with weathered rock mixtures.

Difference between weathering and erosion

Six pairs of eyes were staring at me blankly. Cows, to be precise. It’s amazing how big those creatures are, particularly when you’re sitting on the grass, so I was glad they hadn’t tried to share my little patch of shade yet. I stood up, slung my pack over my shoulder, and stepped out into the bright sunlight.
I’m teaching a field geology class in southwestern Montana. It’s public property, so I can bring my students there without thinking about closed gates or fences. Aside from the stunning geology, there are magnificent views in every direction, a multitude of cacti, wildflowers, and sagebrush, uncommon wildlife, and, of course, cattle. But we’ve come for the rocks: layer after layer, deposited over 300 million years as seafloor sediment, coastal dune, or river gravel. We’re in the Rocky Mountain Fold-Thrust Belt, where the layers reveal unimaginable twists and turns, as well as fault zones that caused mountains to rise long before the current landscape was created.
We can go pretty much anywhere and anywhere over this 3 or 4 square mile field, just like the cows, since the area is controlled by the Bureau of Land Management. Each student produces a geologic map in great detail. They classify the rocks, draw lines on their maps to indicate the borders between various rock units, and interpret geologic history using their maps. It’s challenging work that pays off handsomely, and most students leave with a renewed sense of trust and competence.

Natural forces shift weathered rock and soil from one location to another by erosion.

Let’s draw weathering-erosion & deposition!

Erosion is caused by gravity, running water, glaciers, waves, and wind.

Erosion and weathering for kids -causes and differences

Sediment is the substrate that is moved by erosion.
Erosion, weathering, and deposition are all active processes on the planet.
Gravity pushes everything into Earth’s core, allowing rock and other materials to slide downhill.
Weathering and erosion are caused by water movements (both on land and underground), which alter the land’s surface features and create underground formations.
The following are the results of these processes:
