There are many ways to determine what minerals are present in a sample. You can observe its color, streak, luster, magnetism, cleavage and hardness. Obviously, you can see what color it is and whether it is metallic or cloudy, but other tests may be required. Streak is tested by rubbing the mineral onto a streak slab of concrete to see what color the powder is. Magnetism is determined by putting a magnet next to the sample, or placing it next to a dish of iron filings. Cleavage is determined by cracking the sample to see the way it fractures. Finally, to determine hardness, you scratch test rocks with the sample, like as controls. I hope this answered your question. (Also, questions like this would best fit under chemistry, because geography is the study of political land)
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.
