Air, Land, and Water
Many of the phenomena that we observe on Earth involve interactions among
components of air, water, and land.

Objective Explain how the atmosphere (air), hydrosphere
(water), and lithosphere (land) interact, evolve, and change.

Atmosphere Nearly all the
atmosphere is confined to a thin shell surrounding Earth.

What is the atmosphere made of?
The atmosphere is a mixture of gases, including nitrogen and oxygen with small amounts of water vapor, carbon dioxide, and other trace gases.

Atmosphere The atmosphere is
stratified into layers

Weather occurs in the Troposphere

Altitude and Air Pressure
As altitude increases, air pressure decreases.

Lithosphere- “Rock Ball”
The rock at Earth’s surface forms a nearly continuous shell
![Page 13: Air, Land, and Water](https://reader036.fdocuments.in/reader036/viewer/2022070419/56815ba3550346895dc9a6d6/html5/thumbnails/13.jpg)
Lithospheric Plates
![Page 14: Air, Land, and Water](https://reader036.fdocuments.in/reader036/viewer/2022070419/56815ba3550346895dc9a6d6/html5/thumbnails/14.jpg)
Hydrosphere- “Water Ball”
The majority of the lithosphere is covered by a relatively thin layer of water called the hydrosphere.
![Page 15: Air, Land, and Water](https://reader036.fdocuments.in/reader036/viewer/2022070419/56815ba3550346895dc9a6d6/html5/thumbnails/15.jpg)
Minerals Rocks are
composed of minerals.
Only a few rock-forming minerals make up most of the rocks of Earth.

Minerals

Identification of Minerals
Minerals are identified on the basis of physical properties such as streak, hardness, and reaction to acid.Moh’s Hardness Scale
Streak

Fossils Fossils are usually
found in sedimentary rocks.
Fossils can be used to study past climates and environments.

Weathering and Erosion
The dynamic processes that wear away Earth’s surface include weathering and erosion.
![Page 22: Air, Land, and Water](https://reader036.fdocuments.in/reader036/viewer/2022070419/56815ba3550346895dc9a6d6/html5/thumbnails/22.jpg)
Weathering The process of
weathering breaks down rocks to form sediment.
![Page 23: Air, Land, and Water](https://reader036.fdocuments.in/reader036/viewer/2022070419/56815ba3550346895dc9a6d6/html5/thumbnails/23.jpg)
Erosion Erosion is the
transport of sediment. Gravity is the driving force behind erosion.
Gravity can act directly or through agents such as moving water, wind, and glaciers.

Soil Soil consists of
sediment, organic material, water, and air.

Water Cycle Water circulates
through the atmosphere, lithosphere, and hydrosphere in what is
known as the water cycle.
