Give 5 places in Ghana with their relief features

Answers

Answer:

Relief features (highlands and lowlands) are important in many ways.a) Deposits in Minerals: Many of the highlands in Ghana contain minerals like gold, diamonds, bauxite and manganese. Example, Atewa has large deposits of bauxite.b) Settlement and road construction The lowlands make it easy to build houses, factories and construct roads.c) Rocks for construction: Our houses, factories, roads, dams, bridges are built from rocks quarried from the mountains. Example, the Tema harbor was built with rocks from Shai Hills.d) Fertile Soils: Valley and river plains have fertile soils for cultivation. The rivers deposit minerals on their plains when they overflow on the banks.e) Rainfall: Highlands (usually mountains) influence the development of rain. Highlands act as wind breaks to slow down the wind. As a result the wind rises up and leads to condensation of water vapour and forms clouds which give rain called relief rainfall.d) Watersheds: Highlands in Ghana are the main sources of rivers and watersheds. Example; Rivers Densu, Birim and Ayensu take their source from the Atewa range.

-Some of the highlands serve as tourist sites which help generate revenue. Eg, Mount Afadjato, Kwahu – Mampong ridge etc.

What is a behaviourist psychologist?

Behaviorism, also referred to as behavioral psychology, holds that people's behavior is influenced by their environment. The most basic definition of behavioral psychology is the study and analysis of observed behavior. This branch of psychology had a great influence on many concepts in the middle of the 20th century.

Practitioners of behavioral psychology hold the view that behavior may be analytically investigated and monitored because all behaviors are learned through conditioning that occurs during interactions with an individual's environment. Additionally, behavioral psychologists look at how actions of people affect decisions.

Simply defined, strict behaviorists believe that all behaviors are the results of experience. Everyone, regardless of background, may be made to behave in a certain way with the right instruction. Behaviorism rose to prominence as a school of thought.

Thus, it is behaviourist psychologist.
