Lesson 3 Flashcards
the study of Earth as an integrated system. It seeks to
understand the past, current, and future state of our
planet.
Earth System Science
The interdisciplinary nature of ESS led to the development
of new ideas for research, as well as promoting scientific
studies to people of different backgrounds.

states
that the Earth is a
self-regulating system.
Organisms interact with
their surroundings and
other organisms. These
interactions make Earth
self-sustaining.
The Gaia Hypothesis
NASA scientists aim to
understand Earth’s systems
by using satellites for
long-term observations.
● NASA continuously collects
data through their satellites.
● Scientists and data analysts
process the data for human
use. Examples of uses are for
weather, atmospheric
analysis, and many more.

Satellites can take photos of
the Earth from space for
various purposes.

Earth has 4 major
subsystems, namely:
● The atmosphere,
● The geosphere,
● The hydrosphere, and
● The biosphere.
