Earth system for Grade 11 students .pptx

Earth and life science

1. Earth system

2. Objective: The learners demonstrate an understanding of the different contributions of personalities about Earth’s systems.

3. Review: - Explain the four subsystem of the Earth?

4. Characteristics of the Earth necessary to support life: - Has breathable atmosphere - Abundance of water - Temperature is neither too hot or too cold - Solar energy - Strong magnetic field - Suitable climate

5. How can we understand the different concepts of knowing the planet’s age? How do we solve the various mysteries, such as the formations of mountains and oceans? When did the scientific studies about the Earth system started? To whom do we credit all of these information?

7. The concept of Earth – the whole planet – as a complex interacting system was set out in the late 1960’s. Although the idea of Earth operating like a living organism, with its dynamic processes acting in concert for self-stabilization, was and still is controversial, it has also been a fruitful source of new thinking. The origins and evolution of Earth system science.

8. The period from the late 1960s onwards saw remarkable technological developments in space exploration, new Earth observation technologies, and the development of computers capable of handling and storing very large data sets and running calculations at unprecedented rates.

9. James Hutton (1726-1797) - Scottish geologist, chemist, naturalist, and originator of one of the fundamental principles of geology—uniformitarianism, which explains the features of the Earth’s crust by means of natural processes over geologic time.

10. Robert Mallet (1810–1881) Ireland, “father of seismology.

11. Charles Darwin (1809–1882) - British naturalist, author of On the Origin of Species - known for his contributions to the Science of Evolution - scientific discovery is the unifying theory of the life sciences, explaining the diversity of life.

12. Eduard Suess (1831-1914) - he was the first geologist who used the word and introduced the concept of the biosphere , - describe the part of the earth that supported life. - He is responsible for hypothesising two major former geographical features, the supercontinent Gondwana (proposed in 1861) and the Tethys Ocean .

13. Vladimir Vernadsky - (1863–1945) saw the functioning of the biosphere as a geological force generating a dynamic disequilibrium, which in turn promoted the diversity of life.

14. Angel Alcala (1929) created the artificial coral reefs in the Philippines –Internationally known for his authority on the community ecology, biogeography, and systematics of amphibians and reptiles.

15. Alfred Wegener (1880 – 1930) - is a German climatologist and meteorologist. He was primarily known for his meteorology and as pioneer polar research. - originate the continental drift

16. William ‘Strata’ Smith (1769 – 1839) - was an English geologist, credited with creating the first nationwide geological map. - father of English geology

17. James Ephraim Lovelock (mid 1960) is an independent scientist , environmentalist , and futurist who lives in Devon , England. He is best knownfor proposing the Gaia hypothesis , which postulates that the Earth functions as a self-regulating system.

18. Lynn Margulis - further developed the theory of James Lovelock with American evolutionary theorist during the 1970s.

19. Walter Langbein (1907-1982) - contributed to the growth of scientific hydrology in a number of ways.

20. Richard Blane Alley (1999) - is an American geologist. He has made outstanding contributions to the study of ice, its interactions with the landscape and its link to climate.

21. Paul A. Witherspoon (1919-2012) - the influential leader in hydrologic sciences.
