What is HoneyComb Weathering?
honeycomb weathering is a type of weathering which affects rocks in many different environments where there is a high level of salinty, often on rock walls near the beach or in deserts. Sea spray or wind that is carrying salt lands on a rock surface and the moisture evaporates from the salt and the leftover salt crystalises. The crystalised salt heats up and expands, eroding many holes in the rock surface.
What are some characteristics of chemical weathering?
Some characteristics of chemical weathering include the breaking down of rocks and minerals through chemical reactions, such as dissolution, oxidation, and hydrolysis. It often results in the formation of new minerals and changes in the composition and structure of the original rock. Chemical weathering is influenced by factors such as temperature, moisture, and the presence of certain substances or organisms.
When two pieces of different types of rock are rubbed together one of the rocks often breaks into smaller pieces this is an example of?
mechanical weathering
Is erosion and weathering the same thing?
No, though they are often confused. Here are the definitions:Weathering: the wearing away of rocks in situErosion: the wearing away and taking away of rocks
Why may a geologist have to break a mineral sample to determine its true color?
Rocks are exposed to the elements and undergo weathering. This can cause the minerals that they are composed of and that are exposed at the surface to become discoloured which can make them hard to identify. A geologist will often use a geological hammer to crack the rock sample to see the fresh, unweathered minerals.

Color is often not a useful identification property because?
it can vary widely within a species due to factors such as age, sex, or environmental conditions. Additionally, color can be easily influenced by lighting, background, and other visual cues, making it less reliable for accurate identification purposes.

Why is sandstone not a mineral?
Sandstone is not a mineral because it does not have a definite composition, and often contains several different minerals.

mechanical weathering
The ocean contains many different mineralsWhy?
The ocean contains many different minerals because the minerals are often found near or touching the ocean and trace amounts get dissolved over time resulting in larger amounts.
How does chemical weathering break down rocks?
Chemical weathering often refers to the chemical reactions that take place between acidic rain or ground water and various rock types. It can also refer to the gradual oxidation of minerals by exposure to air and water. The chemical reaction usually results in the gradual dissolution of the rock.

What are the two forms of weathering?
wo important classifications of weathering processes exist - physical and chemical weathering. Mechanical or physical weatheringinvolves the breakdown of rocks and soils through direct contact with atmospheric conditions, such as heat, water, ice and pressure. The second classification, chemical weathering, involves the direct effect of atmospheric chemicals or biologically produced chemicals (also known as biological weathering) in the breakdown of rocks, soils and minerals.[1]The materials left over after the rock breaks down combined with organic material creates soil. The mineral content of the soil is determined by the parent material, thus a soil derived from a single rock type can often be deficient in one or more minerals for good fertility, while a soil weathered from a mix of rock types (as in glacial, aeolian or alluvial sediments) often makes more fertile soil.
Which processes most directly helps create soil from rocks?
Weathering. Weathering is the breaking down of Earth's rocks, soils andminerals through direct contact with the planet'satmosphere. Weatheringoccurs in situ, or "with no movement", and thus should not be confused witherosion, which involves the movement of rocks and minerals by agents suchas water, ice, wind, and gravity. In addition, weathering is the effect ofatmospheric exposure to man-made structures and materials.Two important classifications of weathering processes exist --- physical andchemical weathering.

What effect do anxiety disorders have on people?
Depression affects both men and women, but quite often what they experience and how they respond is different.
