Earth is a single sphere, though not quite perfectly round in shape. Therefore, I assume that the 'spheres overlap' in the question is more about tectonic plates - which indeed overlap at their edges. If I'm wrong, then the question needs more information.
You probably mean "oblate spheroid," which is the 3D analogue of an ellipse. The earth and other planets, due to the competition between rotational momentum and gravity, is an oblate spheroid. You can model an oblate spheroid by rotating an ellipse around its shorter axis, just as you can model a sphere by the rotation of a circle around any diameter.
A hemisphere is one half of the sphere that makes up Earth's surface.
The atmosphere interacts with all living things because it contains oxygen. The lithosphere contains rocks and minerals which are helpful for building materials for various things. The hydrosphere interacts with all the other spheres providing water and nutrients for all living things, and also helps wash and clean other things. All of the above comprise the biosphere. The biosphere interacts with all the other spheres as well (especially the human race) because everything people or animals do affects the air, water or land.
Bucky balls are composed of carbon atoms linked to three other carbon atoms by covalent bonds. However, the carbon atoms are connected in the same pattern of hexagons and pentagons you find on a soccer ball, giving a buck ball the spherical structure as shown in the following figure. Bucky balls, also called fullerenes, were one of the first nanoparticles discovered. A Bucky ball is any molecule composed entirely of carbon, in the form of a hollow sphere, ellipsoid, or a tube. This is the informal term used to describe these compounds which are collectively known as polyhedral carbon molecules. A buck ball is a spherical or ellipsoidal cage made up of covalently bonded carbon atoms
4D refers to a coordinate system made of 4 axes, all at right angles from each other. In common use 4D generally refers to coordinates in 3D Space/Time. 3 of these coordinates are in space. The fourth is the position in time, where time is considered mathematically as a fourth axis that is at right angles to all other axes. 3D space/time geometry is at the heart Einstein's equations of physics. 4 Space, or four dimensional space is like 3D space/time except that the fourth dimension is not considered to be position in time but rather a fourth spatial coordinate that is along an axis at right angles to all other axes. So called "hyper-cubes" and "hyper-spheres" are 4 space equivalents of spheres and cubes. The easiest way to understand 4-space is to think first off about 2-space, or 2D objects. A circle is a 2D object. A sphere is the extension of a circle into the 3rd dimension to make a 3D object. A hyper-sphere is the extension of that Sphere into the fourth dimension to make a 4D object. A 4D hyper sphere has the same relation to a normal 3D sphere as that sphere has to a 2D circle. Note that the term "4D" is also misused in all sorts of marketing jargon to mean other things. The scientific term for this usage is "nonsense."4d is like when you go see a movie you feel it like in sea world a movie was in 4d and water splashed me in the face
The hydrosphere overlaps with the geosphere, biosphere, and atmosphere. Water in the hydrosphere interacts with the land in the geosphere, supports life in the biosphere, and exchanges gases with the atmosphere.
Lithosphere, Hydrosphere, Atmosphere, Biosphere
The four spheres (lithosphere, hydrosphere, atmosphere, and biosphere) do not represent specific elements but rather components of the Earth system. While oxygen is the most abundant element in the Earth's crust, it is not specific to any particular sphere.
A part of the hydrosphere is any body of water.
Tornadoes primarily impact the atmosphere and lithosphere by causing destruction and changes in weather patterns. While they can lead to flooding and affect water bodies, their direct effect on the hydrosphere is minimal compared to other natural disasters like hurricanes.
No a sphere doesn't even have any angles
any two points on the sphere ;)
Any view of a sphere will be a circle.
Because the thread overlap each other.
A sphere does NOT have any edges
Oceans are part of the hydrosphere. The hydrosphere is all the water on Earth at any given moment.
