Earth science can be broken into many branches, which include: geology, oceanography, climatology, meteorology and environmental science. Astronomy is also considered a branch within earth science.Know More
Geology is defined as the study of Earth's natural materials and structures, along with the processes that created them. Geologists study the natural processes on Earth. They also study how resources found on Earth can be used by humans as resources. Oceanography can be considered a sub-branch within geology that studies the environment within the oceans.
Climatology is the study of the Earth's atmosphere. Climatologists try to better understand how and why the climate undergoes changes. Meteorology is similar to climatology but focuses more on short-term weather patterns and natural disasters. Meteorologists use radars, satellites and other tools to monitor and predict weather.
Environmental science focuses on the effects humans have on the Earth's environment. It is closely related to climatology, as environmental scientists are also interested in climate change. Environmental scientists also study how the Earth's environment impacts human health, how to properly clean up and dispose of pollution, how to increase efficiency of industrial techniques in order to reduce their environmental impact and the effects of different chemicals on the environment.
Astronomists study outer space. They use telescopes to monitor and explore far away planets, suns and galaxies. They also help to design and build probes and satellites that are used to further collect information.Learn more about Earth Science
The goal of science as a collective is to produce explanations for the natural world, including how it works, its makeup, and how it came to exist in its current state, according to the University of Berkeley. These goals span a variety of scientific disciplines from astronomy to zoology.Full Answer >
A creep is the slow, downward movement of soil or debris. One factor thought to contribute to a creep is heaving. Heaving is the expansion and contraction of rock fragments during wet and dry cycles.Full Answer >
According to Universe Today, the duration of a day on Earth is the time it takes for the planet to complete a rotation around its axis. The Earth’s rotation takes 23 hours, 56 minutes and 4.1 seconds.Full Answer >
While no one knows for certain how the Earth formed, scientists theorize that it formed over 4 million years ago after the sun went through its initial formation, gravity began to draw heavy particles together into a planet and solar winds blew away lighter gases. These heavy particles became the core of the planet. As the mass continued to grow, heavier particles sank to the center, according to Space.com.Full Answer >
