Top 10 Questions for Geosciences Faculty Member Interview

1. Explain the concept of plate tectonics and its implications for the Earth’s geology?

Plate tectonics is a theory that describes the movement of the Earth’s lithosphere (the rigid outer layer). The lithosphere is divided into several tectonic plates, which move over the Earth’s mantle (the layer below the lithosphere). The movement of the plates is caused by convection currents in the mantle.

• Plate tectonics explains the distribution of earthquakes, volcanoes, and mountain ranges.
• It also explains the formation of new ocean floor and the recycling of old ocean floor back into the mantle.
• Plate tectonics has been an important theory in geology since the 1960s, and it has revolutionized our understanding of the Earth’s geology.

2. Discuss the different types of rocks and their characteristics?

Igneous Rocks

• Formed from the cooling and solidification of magma or lava.
• Examples include granite, basalt, and obsidian.

Sedimentary Rocks

• Formed from the accumulation and compaction of sediment (bits of rock, minerals, or organic matter).
• Examples include sandstone, limestone, and shale.

Metamorphic Rocks

• Formed from existing rocks that have been subjected to high heat and pressure.
• Examples include marble, schist, and gneiss.

3. Describe the different types of faults and their characteristics?

• Dip-slip faults occur when the two sides of the fault move vertically relative to each other.
• Strike-slip faults occur when the two sides of the fault move horizontally relative to each other.
• Oblique-slip faults occur when the two sides of the fault move both vertically and horizontally relative to each other.

4. Explain the concept of uniformitarianism and its importance in geology?

Uniformitarianism is a principle that states that the geological processes that occur today are the same processes that have occurred throughout Earth’s history.

• This principle is important in geology because it allows us to interpret the past based on what we observe in the present.
• For example, if we see a rock layer that contains fossils of marine organisms, we can infer that the area where the rock was formed was once covered by an ocean.

5. What are the different types of glaciers and how do they form?

• Alpine glaciers form in mountain valleys and flow downhill.
• Ice sheets are large, thick sheets of ice that cover large areas of land.
• Ice caps are smaller than ice sheets and cover only part of a mountain or island.

Glaciers form when snow accumulates and compacts over time, turning into ice. The ice then begins to flow under its own weight.

6. Describe the different types of volcanoes and their characteristics?

• Cinder cones are small, steep volcanoes that are built from cinders (small pieces of lava).
• Shield volcanoes are large, gently sloping volcanoes that are built from lava flows.
• Stratovolcanoes are large, composite volcanoes that are built from alternating layers of lava and ash.

7. Explain the concept of groundwater and how it moves underground?

Groundwater is water that is stored in the pores and cracks of rocks and soil.

• Groundwater moves underground through a process called percolation.
• Percolation occurs when water seeps into the ground and flows through the pores and cracks in the rocks and soil.
• The rate of percolation depends on the porosity and permeability of the rocks and soil.

8. What are the different types of weathering and how do they affect rocks?

• Physical weathering is the breakdown of rocks into smaller pieces by physical processes, such as freezing and thawing, erosion, and abrasion.
• Chemical weathering is the breakdown of rocks by chemical processes, such as oxidation, hydrolysis, and carbonation.

Weathering can affect rocks in a number of ways, including:

• Changing the color of the rocks.
• Creating new minerals.
• Breaking down the rocks into smaller pieces.

9. Describe the different types of soil and how they are formed?

• Sandy soils are composed mostly of sand particles.
• Clay soils are composed mostly of clay particles.
• Loam soils are a mixture of sand, clay, and silt particles.

Soils are formed by the weathering of rocks and minerals. The type of soil that is formed depends on the type of rock or mineral that is weathered, the climate, and the vegetation.

10. What are the different types of ecosystems and how do they function?

• Forest ecosystems are dominated by trees.
• Grassland ecosystems are dominated by grasses.
• Desert ecosystems are characterized by a lack of water.
• Tundra ecosystems are characterized by a cold climate and a lack of trees.

Ecosystems function by the interaction of the living organisms in the system with the non-living environment.
