1. What is crystal?

A solid mass such as a mineral, determined by its atomic structure. A single crystal growing without interference has flat faces and such crystals are highly valued. Others crystals growing with interference, such as crystals of quartz found in granite, will not have perfect form/flat faces.

2. What is what are some of the sub-disciplines within the field of Geology?

For instance, if you are thinking - I have a strong interest in physics/chemistry - can I combine such disciplines with geology and still be able to find employment as a geologist?
Geology is a broad field and allows for combining different disciplines - such as physics, chemistry, mathematics, and biology with geology. In fact one of the main reasons students are drawn to geology is because they can easily merge their interests in most scientific fields with geology - an approach that is well-suited for solving environmental problems as the study of the Earth also involves understanding its physics, chemistry and biology!

3. What is Vein in Geology?

Mineral which may fill or comprise a crack in a rock, or masses of rock which occupy fissures in other rocks. Veins may have originated in many different ways and can present a great variety of forms and structures. They are often classified in three groups:
(i.) veins of igneous rock,
(ii.) of sedimentary, and
(iii.) of minerals deposited by water or by gases.

4. What is engineering geologists?

Engineering geologists apply geological data, techniques, and principles to the study of rock and soil surficial materials and groundwater; they investigate geologic factors that affect structures such as bridges, buildings, dams and airports.

5. What is paleontologists?

Paleontologists study fossils to understand past life forms and their changes through time and to reconstruct past environments.

6. What is Sustainable Development?

Sustainable development is the development of industry and natural resources in such a way as not to damage the ability of future generations to meet their basic needs for food, shelter, products, etc.

7. What is environmental geologists?

Environmental geologists study the interaction between the geosphere, hydrosphere, atmosphere, biosphere and human activities. They work to solve problems associated with pollution, waste management, urbanization, and natural hazards, such as flooding and erosion.

8. Explain me industrial Minerals?

A group of minerals and rocks, largely non-metallic, that are of economic value (e.g., gravel, sand, clay, potash, building stone).

9. What is petrologists?

Petrologists determine the origin and natural history of rocks by analyzing mineral composition and grain relationships.

10. What is marine geologists?

Marine geologists investigate the ocean-floor and ocean-continent boundaries; they study ocean basins, continental shelves and coastal environments.
