Introduction to Earth Science
“Earth Science is an integrated study of the Earth's history, composition, and structure, its
atmosphere and oceans, and its environment in space”
Billions year ago, the solar system and the Earth was created and Science has a big part
for us to know that information explaining how and why the Earth and the solar system created
and us humans and living things too. Science is the greatest collective endeavor. It contributes to
ensuring a longer and healthier life. Science is a process of investigation that leads to producing
knowledge, based on observations and creating explanations based on the observation.
Science plays a big role in our lives. The main goal of science is to identify the patterns
in nature and then use those to make predictions and give facts. The development of new
scientific knowledge involves some basic process. To determine on what is happening scientist
collects data and information through observations and measurements. The data collected is used
to answer well-define questions. These data are necessary to scientist for the development of
hypothesis and theories. Once facts are gathered and the principles are being developed, experts
try to explain how or why things happened through observations. Before hypothesis becomes
part of a scientific knowledge, it must repeatedly pass the testing and analysis and when the
hypothesis passed the testing and analysis, it may be elevated to the status of a scientific theory.
Many sciences are used to study and learn about the earth; but, the four basic areas of
Earth Science are Geology, Oceanology, Meteorology, and Astronomy. Geology is primary
Earth Science, it is the study of the Earth. It deals with compositions of Earth materials, Earth
process and Earth structures. It is also have to do with the organisms of the planet and how the
planet is changed overtime. Geology is divided into two broad areas which is the historical
geology which aims to understand the Earth through its 4.6 billion year history, while physical
geology seeks to understand the process beneath and upon the Earth’s surface. The Earth is
called the blue planet because 70% of its surface is covered with water. If we want to know what
and understand this waters, then we must study oceanography or the Science of oceans.
Oceanography merges with chemistry, physics, geology and biology all into one. It also study
about the composition and movement of seawater, coastal processes, sea floor topography and
marine life. Earth science is also Meteorology, it is the science of the atmosphere. Like
oceanography, meteorology associates with different Earth sciences and it is an integrated study
of thin layer of air that is surrounding the earth. Studying space beyond the Earth is important
that’s why we have Astronomy, the science of the universe. Earth is related to all other objects in
space, Astronomy is useful for exploring the origins of Earth.
Our solar system is formed from a vast, rotating cloud of gas and dust it is called the solar
nebula. Each part of the nebula exerted a gravitational force that resulted on make the nebula
