Geology Interview Questions & Answers - Learning Mode

Geology is the study of the Earth, the materials of which it is made, the structure of those materials, and the processes acting upon them. It includes the study of organisms that have inhabited our planet. Physical geology deals with the study of the physical features of the earth and the processes acting on them. This includes volcanoes, earthquakes, rocks, mountains and the oceans; just about any feature of the earth. Historical geology is the study of the history of the earth.

Question: What makes mountains appear purple?

Answer: This is to do with light and the atmosphere.

The way the rays of light strike the mountains at a greater height than us, then reflect and reach our eyes below the height of mountains, coupled with the air in-between, leads to them looking purple, in a similar way to the process with different wavelength light makes the sky look blue on a sunny day.

Question: Which type of rock is critical for the formation of geysers?

Answer: Liquid rock is needed for geysers to form in the form of what is called magma - which is the geological name for liquid rock. Without that, you cannot get geysers forming. Source:
Question: Which kind of volcano is the most destructive?

Answer: Well each type of volcano can be very destructive and if you are talking in human loss of life terms than the answer is any type of volcano that is near dense population.

The most destructive type of volcano though that is generally acknowledged; as such, independent of people is that which is called the stratovolcano. Source:
Question: What is granite?

Answer: Granite is a hard, igneous rock. It is made up of mica, quartz, feldspar and sometimes bits of other rocks as well. Granite is usually pink, white, or grey. It is crystalline and so shines. Source:
Question: How are the layers of schist separated into alternating light and dark minerals?

Answer: The heat and compression deep within the earth?s magma are what cause these unique and interesting layers of striation.

Depending on the particular stresses and strains, heat and pressure applied, and the individual rocks and minerals there in that composed the material, they react differently and this is what causes the banding. Source:
Question: What is the difference between a canyon, gorge, and valley?

Answer: The simplest way to answer this is to define each term, so you can see:

1) A canyon is a deep valley with steep sides thinks of the Grand Canyon most famously to visualize what this is.

2) A gorge is a deep ravine, which usually has a river running through it - though this does not have to be the case.

3) Finally, a valley is any depression, usually of a certain length, in the surface of the land and often contains a river.

Therefore, a canyon is a specific type of va Source:
Question: What layer of the earth does magma form?

Answer: Magma is part of the layer just under the crust.

It reminds us that whilst everything seems solid underfoot actually that is not quite so, and there are only relatively thin layers on top that move and float on a sea of magma underneath, it is this that moves the continents around the surface of the planet, all be it very slowly indeed. Source:
Question: Describe the formation of igneous, sedimentary, and metamorphic rocks?

Answer: Igneous rocks are formed through volcanic action and because of volcanic activity.

Sedimentary rock takes a long time to form and is dead bits of animals laid down in the sea and compressed over millions of years to form rock; anywhere you see sedimentary rock you are seeing the remains of creatures that were once in the ocean a long time ago.

Metamorphic rock is formed through a combination of heat and pressure inside the earth. Source:
Question: Where are Mountains of the Moon?

Answer: These are a mountain range, along Zaire and Uganda in East Africa. Source:
Question: What ways can igneous rock form two ways?

Answer: Igneous rocks - got to that stage of your geography or chemistry class already?

Well here is a little information for you on the ways in which igneous rocks can form.

Igneous rocks are created when melted material crystallizes, e.g. from magma.

There are two formation methods, the first is that they form on the surface and these are called extrusive igneous rocks, or they can form inside the crust, and these ones are called intrusive igneous rocks. Source:
Question: What is a hypothesis?

Answer: A hypothesis is a postulation as to what could be the case; it is a suggestion as to something that accurately models and explains some aspect in reality.

Then the hypothesis can be tested by getting it to make a prediction, then performing the actual experiment it predicts the outcome of, and see if the outcome matches the prediction.

The more experiments in practice the hypothesis can model and explain the better it is seen to be. Source:
Question: What is coal?

Answer: The remains of trees and shrubs grew millions of years ago, when the weather was mild and moist. Source:
Question: Soils take how many years to form?

Answer: There is no answer to this as it varies very much depending on the type of soil you are talking about and the conditions on earth at the time.

In places that are very warm or very wet with fast moving waters for instance then times are quicker than places where very little happens for thousands of years at a time.

However, the process is very slow indeed and therefore, you would be looking at hundreds of years to produce an inch of soil - and 1,000 years+ to get two or more inches. Source:
Question: What are the three major types of rocks?

Answer: The three types of rocks are as follows:

1) Igneous (from volcanoes etc)

2) Sedimentary (Dead Sea creatures, time and pressure)

3) Metamorphic (other rock types compressed, squished, heated and geologically stressed in massive temperatures and pressure fairly deep in the earth) Source:
Question: What is the mantle made of?

Answer: Earth's mantle - what is it made of - well, many things indeed, but mainly the following:

Compounds of the following metals or semi-metals, along with oxygen compounds:

1) Iron compounds

2) Magnesium compounds

3) Aluminum compounds

4) Silicon compounds Source:
Question: How can sedimentary processes concentrate and form resources? 2. Give an example of a resource formed by a sedimentary process?

Answer: Limestone is formed from pressure applied over time to dead creatures in the sea. Oil is formed because of sedimentary processes and which is one of the most important resources. Source:
Question: How do geologists find out the age of mountains?

Answer: Various ways and techniques can be used. With many mountains, the rock in the mountain can be sampled and then a dating technique applied to find the age.

For instance, radiometric dating may be used to find the age of the rock. These techniques exploit the half-life of naturally occurring radioactive isotopes of elements present in tiny quantities to help work out how old something is.

With some mountains other techniques may be used, for instance at a plate boundary scientists ma Source:
Question: Where there super continents before pangea?

Answer: Pangaea is used to describe the state where all the land on earth was one great big landmass and therefore there was just one ocean too which was everything that surrounded that land mass.

Therefore, before Pangaea or all the land was linked you are asking whether the land was previously split before it came together. That is possible - we do not know the answer. However, we read about it and current theory suggests that yes there have been break ups and come together forming super contin Source:
Question: What is the difference between the geoid and the surface of the earth?

Answer: The geoid is an imaginary surface that equivalences with the average (mean) sea level around the world.

Therefore, it is not an actual or real thing like the continents themselves that form the surface of the earth, but merely a useful model that we can imagine to extend through the continents. Source:
Question: What is china clay?

Answer: It is a type of clay first used by the Chinese for making chinaware and porcelain. Source:
