Answer:
Organic and traditional farming are fundamentally different in that conventional farming depends on chemical intervention to combat pests and weeds and provide plant nutrition. Organic farming, on the other hand, produces balanced, abundant food by relying on natural concepts such as biodiversity and composting.
Answer:
C. Magma from venus mantle erupted as lava.
Explanation:
A volcano is a landform which results from the eruption of molten rocks (lava) on the surface. Volcanic rocks are a special type of igneous rock that forms when molten rock cools and solidifies on the surface.
From the little description given, option C gives the best scientific explanation to the occurrence of the volcano on the surface of Venus. For a planet like venus which is presently not active and little to no movement occurs within the plates, the volcanisim must have occurred when the planet was relatively young and it must have been millions of years ago.
It is widely believed that Venus was geologically active in times past. Mantle generated lava must have solidified on the surface in times past to have formed the volcano.
Evaluating other options:
... Impact of space objects on Venus would lead to the formation of a crater which is a depression on the surface. The rock would be mostly metamorphic.
.... If water was ever present in Venus, they would have produced sedimentary rocks instead. The erosive power of water is not high enough to cut through the crust. Also, water would not aid the formation of volcanoes.
.... Heat is not enough to from volcanoes. Other factors are also in play.
