What are 3 interesting facts about minerals?
- Scientists who study minerals are called mineralogists.
- Around 99% of the minerals in the Earth’s crust are made up of eight elements including oxygen, silicon, aluminum, iron, calcium, sodium, potassium, and magnesium.
What are 3 things geologist do?
Geologists study earth processes such as earthquakes, landslides, floods, and volcanic eruptions . When geologists investigate earth materials, they not only investigate metals and minerals, but also look for oil, natural gas, water, and methods to extract these.
What are the three most important concepts in geology?
The major concepts in geology include Earth’s systems, plate tectonics, geologic time, Earth’s structure , Earth’s minerals, fossils, landforms, processes that shape the earth, weathering and erosion, radioactivity, rock composition, and the rock cycle.
What is interesting about geology?
Geology is not only the study of rocks , but also the study of how they change. Geology often gives clues about the history of the Earth. It does this by providing geologists with clues about the various climates on Earth, plate tectonics, and the history of life on Earth.
Are geologists happy?
Geologists are about average in terms of happiness . At CareerExplorer, we conduct an ongoing survey with millions of people and ask them how satisfied they are with their careers. As it turns out, geologists rate their career happiness 3.3 out of 5 stars which puts them in the top 46% of careers.
Is geology a tough subject?
Students interested in geology can prepare by taking basic courses in math, science and geography. Geology is not any more difficult or easy to learn than any other academic subject . It is however a science and requires time and dedication if you want to achieve success in the subject.
What rock is the most common?
Sedimentary rocks are the most common rocks exposed on Earth’s surface but are only a minor constituent of the entire crust, which is dominated by igneous and metamorphic rocks.
Does Obsidian exist?
obsidian, igneous rock occurring as a natural glass formed by the rapid cooling of viscous lava from volcanoes . Obsidian is extremely rich in silica (about 65 to 80 percent), is low in water, and has a chemical composition similar to rhyolite. Obsidian has a glassy lustre and is slightly harder than window glass.
What is the oldest mineral found on Earth?
Zircons , the oldest minerals on Earth, preserve robust records of chemical and isotopic characteristics of the rocks in which they form.
Is being a geologist fun?
They study the history of the Earth in terms of materials, rocks, and minerals. It can be a very exciting and stimulating career choice for someone who is interested in the processes that shape the Earth’s surface such as volcanic eruptions, landslides, floods, and earthquakes.
What kind of jobs can a geologist do?
There are many careers available to geologists in fields including environmental geology and geoscience, pollution control, glacial geology, geological surveying, water supplies , engineering geology, ground investigation, geochemistry, volcanology, field seismology and geotechnical engineering.

What does Earth Science Study?
Earth science is the study of the Earth’s structure, properties, processes, and four and a half billion years of biotic evolution . ... Their knowledge about the structure, stratigraphy, and chemical composition of the earth’s crust helps us locate resources that sustain and advance our quality of life.
