Answer:
Shifting cultivation is not included in commercial farming.
Explanation:
There are multiple types of farming, and that is prevailing more and more is commercial farming. This type of farming is characterized by large-scale production, with higher amounts produced in a smaller area, new types of high productivity seeds, use a lot of pesticides, being heavily mechanized, etc. The reason why this type of farming has developed and is becoming dominant is that there has been an exponential rise in food demand because of the growing global population and increase in consumption per capita.
Something that is not used in commercial farming is the shifting cultivation method. This method basically means that every season a new type of crop is planted, thus leaving the soil to recover naturally and restore nutrients needed for when the initial crops are planted again. The commercial farming doesn't use this method because it simply relies on using high amounts of fertilizers, so every season that soil is enriched with nutrients.
Answer:
igneous rock, would be lower
Explanation:
- As the composition of the magma depends on the ricks form which it was formed along with the condition of the melting, has a high level of iron, magnesium, and calcium, and is likely to be determined by the oxygen and the silicon.
- And virtually all the igneous rocks are derived for the magmas that are caused by the partial melting of the original rocks, either in the upper mantle o the crust.
- <u>The main mechanism, that meets the cracks in the zone is called the decomposition melting or the flux melting as the ricks are being moved to the surface. Thus magma continues to cool and the crystals start to form.</u>
