The task involves identifying and describing the four main spheres of Earth:
Geosphere,
Atmosphere,
Hydrosphere, and
Biosphere. Let's solve it step by step.
1. Geosphere
-
Description: This sphere is the solid part of the Earth.
-
Components: It is made of
rocks and
soil.
-
Answer: The Geosphere includes the Earth's crust, mantle, and core.
2. Atmosphere
-
Description: This layer includes all the gases that surround the Earth. It protects us from harmful solar radiation and meteoroids.
-
Components: It consists of nitrogen, oxygen, carbon dioxide, and other gases.
-
Answer: The Atmosphere is the gaseous layer surrounding the Earth.
3. Hydrosphere
-
Description: All the water on the planet is in this sphere. We can find it in oceans, rivers, lakes, and glaciers.
-
Components: It includes liquid water (oceans, lakes), frozen water (ice caps, glaciers), and water vapor (in the atmosphere).
-
Answer: The Hydrosphere encompasses all forms of water on Earth.
4. Biosphere
-
Description: This is the sphere where life exists in all forms, including plants and animals.
-
Components: It includes all living organisms (plants, animals, microorganisms) and their interactions with the other spheres.
-
Answer: The Biosphere is the zone where life thrives, spanning parts of the atmosphere, hydrosphere, and geosphere.
Filling in the Blanks:
1.
Yellow Box (Geosphere):
- "This sphere is the solid part of the Earth, it is made of
rocks and
soil."
2.
Gray Box (Atmosphere):
- "This layer includes all the
gases that surround the Earth. It protects us from the
harmful solar radiation and meteoroids."
3.
Blue Box (Hydrosphere):
- "All the
water of the planet is in this sphere. We can find it in
oceans, rivers, lakes, and glaciers."
4.
Green Box (Biosphere):
- "This is the sphere where life exists in all forms, including
plants and
animals."
Final Answer:
\[
\boxed{
\begin{array}{l}
\text{Geosphere: Rocks and Soil} \\
\text{Atmosphere: Gases; Harmful Solar Radiation and Meteoroids} \\
\text{Hydrosphere: Water; Oceans, Rivers, Lakes, and Glaciers} \\
\text{Biosphere: Plants and Animals}
\end{array}
}
\]
