A stationary front is depicted in the picture at L. A stationary from is a narrow zone separating two air masses in which neither air mass is displacing the other. When this occurs there is a stall in the motion of the front. The blue triangles point away from the cold air and the red semicircles point away from the warm air.
Answer:
Because of their wave movement, P waves travel through any kind of material, whether it is a solid, liquid or gas. On the other hand, S waves only move through solids and are stopped by liquids and gases. ... This also accounts why fewer S waves are recorded than P waves.
Answer:
<u>There are a total six crystal system like triclinic, monoclinic, tetragonal, hexagonal, orthorhombic and cubic</u>.
Explanation:
- The crystal forms of the crystal family refer to several classes of crystals that are informally formed by the grouping of crystal and being divided based on sources.
- The crystal; system that corresponds to space groups is given a lattice system giving them a 32 point scale.
- These points are assigned to the trigonal crystal system which consists of all the above 6 system forms of crystals.
- Their name is given by Whittaker who formed these crystal structures as protein structures
Answer: An elliptical galaxy is a type of galaxy with an approximately ellipsoidal shape and a smooth, nearly featureless image. They are one of the three main classes of galaxy described by Edwin Hubble in his Hubble sequence and 1936 work The Realm of the Nebulae, along with spiral and lenticular galaxies. Elliptical (E) galaxies are, together with lenticular galaxies (S0) with their large-scale disks, and ES galaxies with their intermediate scale disks, a subset of the "early-type" galaxy population.
