How deep is the ocean? How do volcanoes run? Why do eclipses happen? How does photosynthesis happen?
Thousands year ago, answering these question is not an easy thing. Even, people didn’t know what is called volcano or what photosynthesis is. But now, everything has changed thanks to the appearance of science, especially Earth Science.
And the truth is that we can easily find the answer for each above question because all are explained carefully by scientists and researchers.
So, are you curious about the Earth Science? What is it? Why does investigating it help to solve lots of issues in our life? Does it have any connection to other sciences? Just follow us and then all your queries will be answered right away.
What is the Earth Science?
Literally, it is the study of the Earth as well as its neighbors in space. With a variety of exciting and practical applications, this subject is always interesting to learn. Lots of Earth scientists avail their knowledge of the Earth in order to discover and advance energy and mineral resources in life. Also, they have studied the influence of human activity on Earth’s environment and illustrated methods to safeguard the planet.
It can be said that Earth Science is a huge term that includes lots of aspects. Normally, the Earth scientists only study one aspect and then work with the others to answer the complex questions about the Earth.

What are the sciences that are included in Earth Science? A lot, actually. But, instead of listing all, we only focus on four main areas to ensure that you can understand basic information first.
Four main branches of Earth Science
1.Science of the Earth – Geology
When it comes to the Earth Science, the geology is considered as the first primary branch. It’s the investigation of the geosphere or rock parts of the Earth. The scientists and researchers in this field are mainly studying things about the movement of the Earth’s continents, volcanoes, rock types, sedimentation, earthquakes, or erosion.
2.Science of the atmosphere – Meteorology
Meteorology is the study of our atmosphere, weather, and climate. It’s known as a practical science because we all care about the weather. For instance, how weather changes over time in response to people’s actions is always an urgent concern worldwide.
And those who are working as meteorologists often study items related to humidity, precipitation, atmospheric layers, pressure, heat transfer, global air circulation, etc. They also read and interpret the weather map in order to assess the weather patterns in weeks and months.
3.Science of the Universe – Astronomy
Why do we talk about the astronomy? Does it have any concern with the Earth Science? Of course, yes. Let’s see some examples below and then you will understand.
Do you know that the appearance of the moon affects the ocean’s tidal system every month? Do you know that the energy from the Sun drives out our climate and weather? Do you know that the asteroid effects have regularly devastated inhabitants on Earth?
That’s why studying astronomy is extremely critical to help us understand the Earth. From that point, astronomers also avail their knowledge of Earth materials, history and processes to explore and learn about other planets.
4.Science of the Oceans – Oceanography
We all know that our Earth’s surface holds about 71% water and has 5 main oceans consisting of Atlantic, Pacific, Indian, Southern, and Arctic.
For this reason, the Earth’s oceans have become the necessary resources for different areas such as energy source, food, and other commodities. Even, the oceans play an important influence on the weather. And any change in the oceans can moderate or dive the climate change.
Via studying the oceans, the oceanographers work together to develop the ocean as an important resource as well as protecting it from human impact.
Is the Earth Science important?
A big YES, of course.
Today, we are living in a period when our Earth and people face up to lots of challenges all the times.
When the climate is changing, that means this is being created by human activities. Therefore, the Earth scientists try to help us recognize this issue and learn how to deal with it. In addition, they are challenged to discover new sources of metal or other minerals since the available ones are gradually disappeared. Plus, they need to develop new sources of energy that can create minimal impacts on our climate and decide how our Earth is increasing population can survive and avoid severe threats like earthquake, volcanoes, floods, landslides, etc.
Since the Earth Science covers all aspects from the deep inner core to the exterior layers of the atmosphere, what we want to highlight from the beginning to end is that this science is extremely critical and necessary in our life.
Generally speaking, reading this article points out the definition and importance of the Earth Science. Moreover, it explains necessary information about four main branches including geology, meteorology, astronomy, and oceanography. What’s more, you soon find out that there are close connections between them.

What is “chemical”?
Maybe most of us will connect chemicals with test tubes, experimental flasks, or the “hazard” signs like skull and crossbones. In fact a chemical is an element, the element is the purest form of chemical known to man.When multiple elements combine, a chemical compound is formed. Anything made up of matter, or anything that is considered a solid, liquid, or gas, is made up of chemicals.
Are all chemicals dangerous?
Of course No. A large number of chemicals not only quite safe but also can make our life better, more convenient and pleasurable.Even the human body is made of chemicals. Just as Margot Wallstrom the former Vice President of the European Commission said “chemicals are a blessing and a curse”.
Can we live without Chemical?
Life without chemistry? We would be back to the stone age! Chemicals play a vital role in our survival, nearly everything a person uses throughout the day is composed of chemicals. They are combined in different ways as to create different substances—from the water one drinks to the gasoline that provides the energy for an automobile.
How does chemistry change life?
The answer lies in our basic life needs: clothing, eating, housing, and transportation etc.
Clothing: Textile chemical crafts make our clothes fabrics more various;printing and dyeing chemical process makes our clothes more colorful and beautiful; washing chemical process helps us remove the stain and make our cloth as clean as new…
Eating: Chemical swelling agent brings us the delicious food such as bread , cake, steam bun and so on; chemical edible pigment makes our food more colorful and beautiful, which can raise our appetite, increase the secretion of digestive juice, and conducive to digestion and absorption;chemical nutrition fortifier compensates nutritional defects in natural food,help to balance nutrition…
Housing: Chemical corrosion-resistant materials make our house and other buildings more rugged and safer; chemical building adhesives make our house more delicate and strict; chemical coatings make our house more beautiful, and home more warm and sweet…
Transportation: Chemical rubber technology brings us durable automobile tires; petrochemical provides the fuels for auto-mobile, ship and plan to move; materials chemical make our transportation tools more firm, safe and beautiful…
