According to the information provided in the image the emergence of photosynthetic organisms contribute to the weathering of rock was
option B was the correct answer
what does weathering of rock refers to ?
Rock Weathering: Weathering is the transformation of rocks into more stable materials as a result of exposure to agents such as air, water, and organic fluids. No rock is impervious to weathering.
Weathering is the process through which rocks disintegrate and decompose in situ. It signifies that weathering is a static process. Weathering, as defined by C.D. Oilier (1969), is "the breakdown and modification of minerals near the earth's surface to produce products that are more in balance with freshly imposed physico-chemical circumstances."
The rock was formed when oxygen reacted with other elements to form earths crust which weathered the rock.
that is the oxygen that is produced from the photosynthetic process was reacted to the hydrogen that is present in the gases formed the water and that lead to the weathering of the rock.
As we know, the number of protons specifies Atomic number. So, the atomic number for this element is 19. Now, element having 19 protons must have 19 electrons, So, writing electronic configuration for 19 electrons,
1s², 2s², 2p⁶, 3s², 3p⁶, 4s¹
So, valence shell is 4, means element is present in 4rt period. And number of electrons in 4rth shell are 1. Means element belong to group 1.
Take periodic table go to period 4 and group 1. Its Potassium (K).
