Which of the following is NOT a common sample preparation technique used in geomorphology?

  1. Sieving

  2. Thin sectioning

  3. Polishing

  4. Dissolution


Correct Option: D
Explanation:

Dissolution is not a common sample preparation technique used in geomorphology. Sieving, thin sectioning, and polishing are all commonly used to prepare samples for analysis.

What is the purpose of thin sectioning in geomorphology?

  1. To create a two-dimensional representation of a rock sample

  2. To measure the grain size of a sediment sample

  3. To determine the chemical composition of a mineral sample

  4. To identify the fossils present in a rock sample


Correct Option: A
Explanation:

Thin sectioning is used to create a two-dimensional representation of a rock sample, which can then be studied under a microscope to identify the minerals and textures present.

Which of the following is NOT a common data analysis technique used in geomorphology?

  1. Grain size analysis

  2. X-ray diffraction

  3. Scanning electron microscopy

  4. Radiocarbon dating


Correct Option: D
Explanation:

Radiocarbon dating is not a common data analysis technique used in geomorphology. Grain size analysis, X-ray diffraction, and scanning electron microscopy are all commonly used to analyze geomorphic samples.

What is the purpose of grain size analysis in geomorphology?

  1. To determine the texture of a sediment sample

  2. To measure the porosity of a rock sample

  3. To identify the minerals present in a rock sample

  4. To determine the age of a rock sample


Correct Option: A
Explanation:

Grain size analysis is used to determine the texture of a sediment sample, which can provide information about the depositional environment and the transport history of the sediment.

Which of the following is NOT a common interpretation of geomorphic data?

  1. The age of a landform

  2. The climate of a region

  3. The tectonic history of an area

  4. The vegetation of a region


Correct Option: D
Explanation:

The vegetation of a region is not a common interpretation of geomorphic data. The age of a landform, the climate of a region, and the tectonic history of an area are all common interpretations of geomorphic data.
