Rock flour is a product of both weathering and erosion processes. Weathering breaks down rocks into smaller particles, while erosion transports these particles to another location. Rock flour is created when rocks are weathered into very fine particles, which are then transported by erosion processes such as glacial movement or river flow.
Humans contribute to weathering of rocks on Earth through activities such as mining, construction, agriculture, and deforestation. These activities can lead to physical weathering through the disturbance of rocks and soil, as well as chemical weathering through the release of pollutants that react with and deteriorate rocks. Overall, human activities can accelerate the natural processes of weathering and erosion.
Signs of a potential tornado include rotation in the clouds, a persistent lowering of the cloud base, and a hole opening up in the clouds near the back of a storm (these are all potential precursors). Other signs include a funnel or con shaped extension of the cloud base, and swirling debris on the ground, indicating that a tornado or funnel cloud has formed.
A striation of any length is a sure sign of glacial activity in the past. A striation is formed when a glacier scrapes moraine (load) against the rock face, forming a mark known as a striation. The mark shows that the area was once dominated by glacial activity.
Erratics are a key sign of glacial activity. These are large rocks resting on top of soil, unlike monadnocks which are pinnacles left over from riparian erosion. The rock is carried from some distant mountain on glacial ice, and abandoned on a plain when the ice stops moving and melts. Glacial valleys have a characteristic U shape to them, as opposed to the V shape of valleys carved by water. Often glaciers leave broken rock and rubble in a wavey line known as a terminal moraine, or along the sides of the moving ice in formations known as lateral moraines. Ice also gouges series of characteristic grooves or scars on mountain rock faces, indicative of glacial activity.

yes I have an original red top flour porcelain sign it is a convex sign and measures 17inx22in it was used to advertise flour for the aunt jemima mill in st Joseph mo around 1910 anymore questions please e-mail cassmark9431@sbcglobal.net
its rock bottom
yes an original, and it is for sale if intrested
Chemical and biological weathering are different because: a) biological weathering - this means that if a seed of a plant gets coincidentally deposited in a crack in a rock, if it is humid enough, the see will grow. it's roots will spread out and eventually break the rock. b) chemical weathering - this means that chemicals in rain/acid rain weathers away the rock.
what a sign mean that has a red circle with rock in it and a red line through it
The sign language for rock can vary depending on the context. One common sign is to make a fist with your dominant hand and then shake it side to side, mimicking the movement of a rock. Another sign is to make a "C" shape with your hand and then tap it against the back of your other hand. These signs represent the concept of a rock or the verb "rocking."
They do the thumbs up sign because they rock!
Hi: Pound one fist on the back of the other hand; point 2 fingers down (like legs) and jump them over the other hand. [technically: rock - jump over]
Compression.
The rocks and soil from around the area. The rocks may display various waves of a sort, explaining how it was formed, what creatures may have previously been there, as well as erosion from rain. The tree's may show being struck by lightning more than once, and if the soil is very exposed or spread out, that could be a sign of floods or rain.
