Earth Science

What are the five areas of study that Earth Science emcompasses?
1. astronomy,
2. meteorology,
3. geology,
4. oceanography and
5. environmental science
Scientists use Scientific Methods to investigate.
Scientists use Scientific Methods to investigate.
The temperature of the earth’s core is 7227 C.
What percentage of freshwater is contained in glaciers
70%
What is the CRUST?
thin, rocky outer lay of the earth, used as the hardened exterior or surface part of the bread.
Astronomy
The study of objects beyond Earth’s atmosphere
meteorology
The study of the forces and processes that cause the atmosphere to change and produce weather
geology
The study of the materials that make up Earth, the processes that form and change these materials, and the history of the planet and its life-forms since its origin
Geologists identify rocks, study glacial movements, interpret clues to Earth’s 4.6-billion-year history, and determine how forces change our planet.
oceanography
The study of Earth’s oceans, which cover nearly three-fourths of the planet. Oceanographers study the creatures that inhabit salt water, measure different physical and chemical properties of the oceans, and observe various processes in these bodies of water.
environmental science
The study of the interactions of organisms and their surroundings.
Environmental scientists study how organisms impact the environment both positively and negatively. The topics an environmental scientist might study include natural resources, pollution, alternative energy sources, and the impact of humans on the atmosphere.
geosphere
The area from the surface of Earth down to its center.
The geosphere is divided into three main parts: the crust, mantle, and core.
atmosphere
the mass of air surrounding the Earth
hydrosphere
the watery layer of the earth’s surface
biosphere
The biosphere includes all organisms on Earth as well as the environments in which they live. Most organisms live within a few meters of Earth’s surface, but some exist deep beneath the ocean’s surface, and others live high atop Earth’s mountains. All of Earth’s life-forms require interaction with at least one of the other systems for their survival.
Earth is divided into four independent systems. Name the systems.

Identifying the interrelationships between Earth systems leads to..
specialties and subspecialties.
Technology is important, not only in science,…but
in everyday life
Explain why it is helpful to identify specialties and subspecialties of Earth Science.
The study of our planet is a broad endeavor, and as such, each of the five major areas of Earth science consists of a variety of subspecialties.
Apply what are the three items you use on a daily basis that have come from research in Earth Science.
thermometer, eat vegetables, vehicles (iron)????economical vehicles
Compare and contrast Earth’s geology and geoshpere.
Hypothesize about human impact on each of Earth’s systems.
Compare and contrast hydrosphere and biosphere.
