Which answer is not a real life example of geologic cross sections?

What are cross sections in geology?

A geological cross-section is a graphic representation of the intersection of the geological bodies in the subsurface with a vertical plane of a certain orientation.

What does a cross-section show about the earth?

The Cross section of the Earth is a visualization of the composition of the Earth in geological terms. The planet Earth is an immensely complicated and dynamic system, with many different physical and chemical properties.

How do you create a geological cross section?

1. Select a section line.
2. Construct a topographic profile along the line of section.
3. Transfer contacts from the map to the topographic profile.
4. Project dip data into the cross section line.
5. Calculate and plot apparent dips on the topographic profile.
6. Construct the subsurface interpretation.

How do you read a geological cross section?

Quote from video:First by the accumulation of weathered rock debris that was distributed by water wind and gravity. Second though less abundant rock is produced by precipitation.


What is a cross-section of a map?

Definition: Cross-sections are represented on a map by a line which will often be labelled A at one end and B at the other. If you were to slice through the map along this line, and look back, you would be able to see what is happening underneath the ground.

What are the 3 main categories of geologic structures?

A knowledge of common types of geological structures is also essential. Geologists recognize three main classes of structure caused by deformation in Earth’s crust: unconformities, faults and fractures, and folds. We usually think of rocks as being very hard and brittle.

What are some examples of geological structures?

What are geological structures?

• faults.
• bedding planes.
• the edges of igneous intrusions (intrusive contacts)
• ancient erosion surfaces (unconformities)




What are geological layers called?

Rock layers are also called strata (the plural form of the Latin word stratum), and stratigraphy is the science of strata.

What are primary geological structures?

A primary structure is defined by Wilkerson (2019) as, “any structure that develops prior to or during the formation of the rock.” Primary structures are non-tectonic, meaning they form during sedimentary deposition, or in the case of metamorphic rock, during crystallization.

What causes cross-bedding?

Cross-bedding is formed by the downstream migration of bedforms such as ripples or dunes in a flowing fluid. The fluid flow causes sand grains to saltate up the stoss (upstream) side of the bedform and collect at the peak until the angle of repose is reached.

What is geological structure India?

The stratigraphy of India can be divided into several divisions such as Archean System, Dharwar System, Cudappah system, Vindhyan system, Paleozoic, Mesozoic, Gondwana, Deccan Trap, Tertiary and Alluvial. The Geology of India is an essential aspect to be studied, in Earth Science and geography.

What is an example of a secondary protein structure?

A secondary structure of a protein pertains to the folding of a polypeptide chain, resulting in an alpha helix, beta sheet or a random coil structure. Another example of a secondary structure is that of a nucleic acid such as the clover leaf structure of tRNA.

Which of the following is not an example of protein secondary structure?

hydrophobic folding is not an example of secondary structure found in proteins. answer is c.

What is an example of a tertiary structure of a protein?

Protein tertiary structure.



For example, amide hydrogen atoms can form H‐bonds with nearby carbonyl oxygens; an alpha helix or beta sheet can zip up, prompted by these small local structures. Hydrophobic interactions among the amino acid side chains also determine tertiary structure.

Which of the following is not true about secondary protein structure?

2. Which of the following is not true about secondary protein structure? Explanation: The hydrophilic/hydrophobic character of amino acid residues is important to protein tertiary structure rather than to secondary structure.

Is not a classified form of conjugated proteins?

Which of the following is not the classified form of conjugated proteins? Explanation: On the basis of the chemical nature of their prosthetic groups conjugated proteins are classified into lipoproteins, glycoproteins and metalloproteins.

Which of the following is not the function of proteins?

Enzymes are proteins made up of amino acids and acts as biological catalysts in our body. However, glucose serves the purpose of energy provider for metabolism which is not a protein.

Which of the following is not correct about alpha helix?

Which of the following is not correct about the α-Helices? Explanation: The structure is stabilized by hydrogen bonds formed between the main chain atoms of residues i and i + 4. The hydrogen bonds are nearly parallel with the helical axis.

Which of the following is not true for protein engineering Mcq?

Which of the following is not true for protein engineering? Explanation: Protein assay is indeed a step in protein engineering. The protein engineering cycle requires a knowledge-based design.

Which of the following is not formed by structural protein?

So, the correct option is ‘Albumin‘.

Which is correct for alpha helix of a protein?

(A) The α helix, a common structural motif of proteins, consists of a right-handed helix with a repeat length of 3.6 amino acid residues per helical turn. The α helix is stabilized by hydrogen bonds between an amide hydrogen of one amino acid and a carbonyl oxygen four amino acids away.

Why does proline not fit into an alpha helix?

The proline residue lacks an amide proton. This precludes hydrogen bonding between it and hydrogen bond acceptors, and thus often restricts the proline residue to the first four positions of an α-helix.

Why is glycine not found in alpha helices?

The amino acid glycine is known to be very small, which is why it destabilizes alpha-helices. Glycine, owing to its small size, can cause bends in the chains, resulting in extreme conformation mobility.

What connects alpha helices?

Ω-loops are so called as they have the general shape of the letter omega. These are usually 6–16 residues long and connect α-helices and β-sheets. They are predominantly found at the protein surface in globular proteins or connecting membrane α-helices at the cytoplasmic or extracellular face.

What are peptides?

Peptides are short strings of amino acids, typically comprising 2–50 amino acids. Amino acids are also the building blocks of proteins, but proteins contain more. Peptides may be easier for the body to absorb than proteins because they are smaller and more broken down than proteins.

What are alpha helix and beta sheets?

The most common types of secondary structures are the α helix and the β pleated sheet. Both structures are held in shape by hydrogen bonds, which form between the carbonyl O of one amino acid and the amino H of another. Images showing hydrogen bonding patterns in beta pleated sheets and alpha helices.
