Answer:
competition
Explanation:
An ecological community is a naturally occurring group of native plants, animals and other organisms that are interacting in a unique habitat. Its structure, composition and distribution are determined by environmental factors such as soil type, position in the landscape, altitude, climate and water availability(Department of Agriculture).
A climax community refers to the last stage of ecological succession in which the community remains relatively unchanged unless it is destroyed by events such as fire or human interference.
Competition between species in the same habitat is an important biotic factor in discussing ecological succession and the emergence of climax communities. Competition leads to a drop in the diversity of species in a given ecosystem because the dominant species live on and reproduce while the other species die off.
The following choices are provided;
One plate moves below the other due to the movements in the inner core.
One plate moves below the other due to the movements in the mantle.
A plate slides past another due to the movements in the inner core.
A plate slides past another due to the movements in the mantle
The answer is; One plate moves below the other due to the movements in the mantle.
It is common that such convergent boundaries have a cascade of volcanic ranges. This is because as the oceanic plate moves below the continental plate the pressure and high temperatures cause the rock to melt and become magma. The magma makes it way up the crust through fissure and erupts.
Answer:
Option (3)
Explanation:
The continental crust is usually thick because it has an average thickness of about 35-40 km. In the high mountain ranges, it is the thickest, forming about 80 km on an average. These are formed when two continental plates form a sandwich pattern by sharing a convergent type of plate boundary.
For example, the thickest part of the crust is the Mt. Everest which lies in the great Himalayan range, which has started to form about 50 million years back. It is geologically the most recent mountain range.
The older mountains are continuously eroded in the geological past, as a result of which the height of the mountains is affected.
Thus, the correct answer is option (3).
