Earth as a Source of Elements
Earth as a Source of Elements - Most elements are formed due to fusion of simple nuclei to give heavier nuclei i.e., nucleosynthesis or nuclear fusion reactions taking place in the stars. Atoms of these elements began to fall together about six billion years ..
The Earth's Crust
Continents and ocean basins (land beneath the oceans) are part of a rocky 'skin' that surrounds the main body of the earth. This skin is called the earth's crust. The crust of the earth is like the skin around an orange or an apple. The thickness of the crust varies fr..

During the formation of the Earth, cooling of gaseous mixtures took place and molten earth condensed to form different earth zones or layers. Each layer that formed on top of the other had a definite chemical composition and thus a distinct distribution of elemen..

The Earth as a Magnet
About AD1600, William Gilbert, who was a court physician of Queen Elizabeth of England, performed certain experiments using spherical lodestones. When he placed small, pivoted magnetic needles at different positions on this sphere, he found that their behavior was quite similar to that of magnetize..

The Earth's Early Development
Scientists theorize that the earth began as a waterless mass of rock surrounded by a cloud of gas. Radioactive materials in the rock and increasing pressure in the earth's interior gradually produced enough heat to melt the interior of the earth. The heavy ..

The strength of the earth's magnetic field is about 10 - 4 tesla or 1 gauss. To describe the magnetic field of earth at any place three quantities or elements are required. They are: Magnetic declination ( q ) Magnetic inclination ( d ) Horizontal component (B H..

I love the interaction and ability to explain the process of math problem in depth! Would like see the same for all future lessons one on one! THANK YOU!!!
This tutor was excellent. very clear on all of the problems. I would like to have more tutoring from Tutor Vista
all my questions were answered in a very clear way and i learned a new math rules which i did not know this service is very helpful - mike
I like the way this tutors double check the work with me and took time to explain each detail. It really helped me to better understand - Harry
