Latitude.
It is measured with 180 degrees imaginary lines that form circles around the Earth east west, parallel to the Equator. These lines are known as parallels.
Earths history of climate is easily understandable through the study of existing rock and shells aquatic organisms. Rocks came into the earth million of years ago. So, the study of age determinism of rock gives an idea of climate through which it has come across. This is called paleontology.
Explanation:
In studying Earth's history of climate scientists take help of available rocks and body parts of aquatic animals. As rocks are the most eventful findings on the earth's surface which has come across million of years and witnessed several changes. These study if changes in rock is called paleontology.
Shells of aquatic animal which found in underwater are also a good evidence of earth's history of climate. It is found in the layers of sedimentary rock which is soft in nature and found in layerwise. Where all the organism became fossil after death and its body parts remains in the form of stone.
Fossils (from the Latin fossilis, which means 'excavated') are the remains or signs of the activity of past organisms.These remains, preserved in sedimentary rocks, may have undergone changes in their composition (by diagenesis) or deformations (by dynamic metamorphism) more or less intense.
Primary economic activities are defined as extracting raw materials. This includes mining, arable and pastoral farming, forestry and fishing.
Secondary economic activities include manufacturing good using raw materials. An example could be anything made in a factory, such as cars or processed foods, to a house or roads.
Tertiary economic activities provide services and good to people. Teachers, shops and doctors provide tertiary economic activities.
1. Declines in primary sector employment
Machines take away the need for manual labor in the primary economic sector.
As there is often higher paid jobs in the tertiary economic sector people begin to get an education and aim for jobs in the tertiary sector instead.
2. Decreases in infant mortality rate
Education of basic health care helps communities give a child a healthy environment growing up.
More availability of medical resources and professionals help to treat the illnesses that could cause the death of an infant.
3. Improvements in women's social status
Higher education for both women and men encourages gender equality.
Women become less dependent on men with more education and can gain better jobs and equal social status.
