The stars that are visible in the local sky on any clear night of the year, at any time of the night, are called Circumpolar stars.
A circumpolar star is a star that is close to one of the celestial poles and never sets below the horizon hence they are visible from one location throughout the year and one can even see them in the daytime if the sun does not glare.
A geological fold occurs when one or a stack of originally flat and planar surfaces, such as sedimentary strata, are bent or curved as a result of permanent deformation. Synsedimentary folds are those due to slumping of sedimentary material before it is lithified. Folds in rocks vary in size from microscopic crinkles to mountain-sized folds. They occur singly as isolated folds and in extensive fold trains of different sizes, on a variety of scales.
Folds form under varied conditions of stress, hydrostatic pressure, pore pressure, and temperature gradient, as evidenced by their presence in soft sediments, the full spectrum of metamorphic rocks, and even as primary flow structures in some igneous rocks. A set of folds distributed on a regional scale constitutes a fold belt, a common feature of orogenic zones. Folds are commonly formed by shortening of existing layers, but may also be formed as a result of displacement on a non-planar fault (fault bend fold), at the tip of a propagating fault (fault propagation fold), by differential compaction or due to the effects of a high-level igneous intrusion e.g. above a laccolith.
A CBRNE incident is one where chemical, biological, radiation and nuclear hazards are present. Thus, you should:
Practice protective measures of time, distance and shielding
Do not enter zone until agent is identified
Answer:
E. all of the above
Explanation:
Shield volcano -
The composition of shield volcano is fluid lava flows , which is very low in viscosity , and hence flows to form a broad sheet of lava , which builds the distinctive form of the volcano .
These volcanoes are large and have very low slope , just like the Hawaiian volcanoes .
The composition of shield volcano are of lava tube and the solidified lava flow .
