Answer:
the outermost layer of Earth's lithosphere
Explanation:
the outermost layer of Earth's lithosphere that makes up the planet's continents and continental shelves and is formed near subduction zones at plate boundaries between continental and oceanic tectonic plates. The continental crust forms nearly all of Earth's land surface.
The correct answer is option (a). Parent material
The soil horizon refers to distinct layers of the soils, which are parallel to one another, but have a different composition from the layer present above and below to it.
The soil horizon can be divided into four different layers. First one is organic layer, which is the topmost layer, below this layer second layer of topsoil is present. Below top soil, subsoil is present. Below subsoil, the bottom most horizon parent material is present.
(705/224) / (224/224)
224/224 = 1.
So (705/224) / (224/224) = (705/224) / (1/1).
Dividing 2 fractions is equal to multiplying the first fraction by the inverse of the second:
(705/224) / (1/1) = (705/224) * (1/1) = 705/224.
Hope this Helps! :)
The first one is commensalism. The second one is mutualism. The last one is parasitism.
