Spheres of Influence: The Earth's Differentiation Into Solid, Liquid, and Gas Layers Spheres of Influence: The Earth's Differentiation Into Solid, Liquid, and Gas Layers. Any person examining their surroundings immediately realizes the vastness of what envelopes him. However, the visible objects of the Earth pale in comparison to what is going on, unseen and unnoticed. The Earth around us is divided into three layers, the gas layer (atmosphere), liquid layer (hydrosphere), and solid layer (land). These layers developed and evolved over the course of billions of years and are still changing today.

Sphere Note that the ordinary sphere is a 2-sphere, because it is a 2-dimensional surface (which is embedded in 3-dimensional space). The surface area of the (n − 1)-sphere of radius 1 is. where γ(z) is Euler's Gamma function. Another expression for the surface area is.

Dyson sphere – Montgomery Scott, 2369 (Relics) A Dyson sphere was a colossal sphere constructed around a star, completely surrounding it. The interior of the sphere would absorb the entire energy output of that star, allowing for lifeforms to live on the interior surface almost indefinitely. Such a structure was theorized by the 20th century physicist Freeman Dyson.

The Four Spheres of Earth: Geosphere, Hydrosphere, Biosphere, and Atmosphere The continents, the ocean floor, all of the rocks on the surface, and all of the sand in the deserts are all considered part of the geosphere. Basically, if it looks like solid ground, it's part of the 'ground' sphere.

- How to Calculate the Volume of a Sphere. A sphere is a perfectly round geometrical object that is three dimensional, with every point on its surface equidistant from its center. Many commonly-used objects such as balls or globes are spheres. If you want to calculate the volume of a sphere, you just have to find its radius and plug it into a simple formula, V = ⁴⁄₃πr³.

Quad screen (second-trimester prenatal screening) The quad screen is usually done between 15 and 20 weeks of pregnancy. You'll have a blood sample taken and sent to a lab for analysis. Results are usually available in about a week. The test measures the levels of four substances in your blood: 1  alpha-fetoprotein (AFP), a protein made by the baby.

Hydrosphere Hydrosphere Hydrosphere comprised of the two words: ‘Hydro’ and ‘Sphere’. The word ‘Hydro’ comes from Greek language whose meaning is ‘water’, and the word ‘sphere’ comes from the word ‘sphaira’. Hydrosphere contains the different types of water bodies throughout the whole earth. Hydrosphere can be defined as a non continuous layer of water on the earth. Hydrosphere includes each and every source of water such as lakes, ponds, streams, oceans, etc. About part of our earth covered with water.

- What is a hemisphere? A hemisphere is half of a sphere. The names comes from hemi which means half, so hemisphere means half a sphere. We often talk about the northern and southern hemispheres …which are the halves of our planet north and south of the equator respectively. Similarly, we have the eastern and western hemispheres, the halves of the globe that are either east or west of the prime meridian. A hemishere is like half of a ball. 1. A half sphere; one half of a sphere or globe, when divided by a plane passing through its center.

- Pythagoras (569-475 B.C., Ionian) was a mathematician who put forward the idea that the universe is made of crystal spheres that encircle the Earth. According to him, the Sun, the Moon, the planets, and the stars travel in separate spheres. When the spheres touch each other, a 'music of the spheres' can be heard. Aristotle (384-322 B.C., Greek), the great philosopher, proved that the Earth is spherical, and believed that it was at the center of the universe.
