A stationary front is depicted in the picture at L. A stationary from is a narrow zone separating two air masses in which neither air mass is displacing the other. When this occurs there is a stall in the motion of the front. The blue triangles point away from the cold air and the red semicircles point away from the warm air.
Igneous rocks are defined as formations made from solidified lava or magma.
When lava or hot Magma reaches the surface of the earth or a water body it quickly cools down and changes it's from from a hot liquid to a solid rock.
The chemical composition of Igenous rocks can vary depending on their location, cooling time etc.
However, most Igenous rocks contain some or all of the following minerals:
1. Quartz
2. Micas
3. Amphiboles
4. Olivines
5. Pyroxenes
6. Feldspathoids
7. Feldspars
Answer:
I didn't understand the question
Some countries that span both Europe and Asia include Turkey, Russia and Kazakhstan. They are called trans continental countries. Even though Europe and Asia are continents in their own rites, geographically speaking they span one landmass known as Eurasia. The landmass rests on the tectonic plate known as the Eurasian plate.
Answer:
Chemical weathering changes the soil pH and affects the crops that grow on them
Explanation:
Chemical weathering refers to the breaking down of rocks through chemical reactions.
Whenever rocks which are chemically active come in contact with acidic rain, they react to form new compounds. These new compounds formed usually have different properties from their parent rocks.
As a result of chemical weathering, changes in the soil properties can occur such as its pH. These changes will affect the nutrients which can be found in them, thus affecting farming practices on such soil.
