Trenches are geological feature is most common at oceanic-continental convergent boundaries.
Explanation:
Usually, the oceanic plate, because it is denser, becomes subducted underneath the continental plate. The enormous stress of the two colliding plates causes the plates to warp abit downwards along the boundary causing a trench to form that stretches the boundary.
As the oceanic plate gets subducted and ‘dives’ into the mantle, it begins to melt into magma. Usually, due to the enormous stress along the boundary, fissures develop on teh continental plate along teh boundary. The magma rises through these fissures and erupts at the surface. Several mountains form long the boundary forming another signature geological feature of convergent boundary which is volcanic arc mountains.

The effect that malnutrition have on the fetus during critical development in pregnancy is that the impairment of the development of an organ is irreversible. Maternal malnutrition can adversely affect the division and replication of cells in the embryo at this stage, impairing its development. The effects of malnutrition during critical periods of pregnancy are seen in defects of the nervous system of the embryo, poor dental health among other effects.
Answer:
The type of biodiversity been practiced is REFORESTATION .
Explanation:
Reforestation is the deliberate or natural process by which destroyed plants are re-planted in a particular forest. Deforestation usually brings about destruction of different plants species and this normally throws the ecosystem out of balance. The negative process can be reversed by mean of reforestation, in which new plants are planted in the place of the destroyed ones.
Answer:
Actually, the main pigmenting (coloring) agents in soils are organic matter, iron, and, to a lesser extent, manganese. When these agents are not covering the mineral grains, the natural color of the grains is visible. Colour is a simple method of classifying soil. Black/dark brown soil usually indicates the presence of decaying organic matter so is generally fertile. Pale brown/yellow soil often indicates that organic matter and nutrients are low and this generally means poor fertility and structure.he colour of the soil varies from one place to the other because soil is formed out of different types of rock . Since rocks are of different colours and textures , the colour of the soil varies from one place to another .
