If you want to know this because it is your homework (Yes, I am talking about Ms.Brooking's grade 7 class) then tough luck because you guys have to think about this yourself.
But if not, thank you for your interest in structures, but I am sorry that I have not written an answer.
Sincerely,

Shell structure
It is a shell because the structure is with a hallow, curved shape
Shell structures have solid surfaces. They are hollow and there shape is often curved.Eg: Eggs, helmets, conch shell etc.Some of the examples of shell structures are storage tanks (water, oil, gas), domed roofs, and pressure vessels.
This shell is known as Laba Laba or Spider shell. This is made by inlaying shell in resin.This is what I could find on Laba Laba shell. All I know is that they are sometimes (oftentimes) breathtaking.Basically, it is shell (MOP, Abalone, whatever color shell you see) laid into patterns in a plastic base

chairs are shell/solid structures because it is a solid and can be considered a frame
Shell structures are enclosed and hollow in the middle e.g. a snail shell or a house. Frame structures are open on the sides e.g. a tree or the Eiffel tower.
Some structures are combinations of different types of structures:- Football helmets are shell structures - to protect the head, with a frame structure attached in front - to protect the face.- Hydro-electric dams are mass structures, with frame structures inside to house the generators- Airplanes are frame structures, with a 'skin' that acts like a shell - giving it the added strength to resist stresses and making it lightweight and flexible.- Domed buildings combine shell and frame construction- Warehouses are often built with columns to support the roof (frame) and concrete blocks, (mass structures) which stay in place because of their weight.
A geodesic dome is a spherical or partial - spherical shell structure or lattice shell based on a network of great circles on the surface of a sphere.
mass structure, frame structure and shell structure
FRAME STRUCTURESFrame structures are structures that are made up of rigid (stiff, firm, difficult to bend) parts joined together to form something called a framework. These parts are known as members. There are lots of examples of frame structures such as a bridge - a bridge is a frame structure that spans a gap, and a bicycle is a frame structure that supports a load such as the mass of a person.SHELL STRUCTURESShell structures contain or protect things from the outside and are usually hollow inside. In a shell structure, the outside layer of the structure holds the whole object together. Examples of shell structures are the mug that holds your coffee, the snail shell which both protects and contains the snail, honeycomb which contains and protects bee's honey and shells of nuts.
frame structure
Houses, buildings and stuff that are made up of the different structures. Shell. Frame and Solid. Either it could be combined of the solid or shell or any two. A basket can also be a combination structure. That is if the basket is made of banana leaves or something like that at least.
shell and frame
A geodesic dome is a shell that is made of a lot of small triangles (typically) and is shaped like a sphere. (for more information on this, please go to the wikipedia article, thanks.)
The way you hold it or the way you use it.They can be classified as solid structures frame structures and shell structures .Hoppee it hellps-Selena Gome, Demi Lovato were hereLOVE_YOU_FANS_:)">LOVE YOU FANS :)
