Earth's Spheres
Name the 4 spheres
hydrosphere, geosphere, biosphere, atmosphere
True or False: The atmosphere is the same all over the world?
False
Which system has many landforms?
Geosphere
How does the geosphere & biosphere interact?
Geosphere is a habitat for animals, geosphere is home to plants (soil). We live on the geosphere.
What is the defintion of interaction
an action between two or more things
What is the biosphere?
The Earth system that includes all living things. (plants, animals, humans)
What is a sphere that you have an interdependent (Attached) relationship with? **THIS ANSWER CAN VARY.
Geosphere- we live on the geosphere
Biosphere- friends, family, plants & animals that we eat.
Atmosphere- We breathe air in the atmosphere, protect from UV rays, protect from meteors
Hydrosphere- water we use to drink, shower, swim in.
Name three things that make up the biosphere.
plants, animals, bacteria, fungi
How does the geosphere & hydrosphere interact?
Geosphere depends on water for soil, geosphere is eroding and weathered due to rain, lakes, oceans.
When carbon dioxide dissolves into the ocean -the interaction is between
the atmosphere and the hydrosphere
What is the Geopshere?
The Earth system that includes all non-living things (rocks, minerals, sediments ,etc.)
Name three gases that make up the atmosphere
How might the biosphere be affected if a harmful substance entered the Hydrosphere?
The biosphere may be affected because plants need the hydrosphere for fresh water. Plants can die due to the harmful substance in the water. Animals can also drink water that has been affected and could die from it.
Read the scenario, what two interactions are occurring? The Colorado River forms the Grand Canyon.
Colorado River: Hydrosphere and the Grand Canyon: Geosphere
A thunderstorm is a connection between:
atmosphere and hydrosphere
What is the hydrosphere?
The system that includes all of the water on, under or above Earth
When a volcano erupts how does the ash from the eruption interact with other systems?
When the ash goes into the atmosphere, it can block sunlight from reaching Earth's surface. No sunlight means that plants can't make their own food - which affects the biosphere. Ash can also go into the water cycle through rain or falling into streams or rivers.
How might the biosphere be affected if a harmful substance entered the geosphere?
The biosphere may be affected because plants live in the soil which is apart of the geosphere. Plants can die due to the harmful substance in the soil. Animals can also eat organisms that live in the soil or use the soil as their habitat.
How does the hydrosphere affect the atmosphere?
The hydrosphere influences the atmosphere through evaporation and precipitation. Water evaporates from oceans and lakes, contributing to humidity in the atmosphere, which can lead to cloud formation and precipitation.
How do human activities impact the interactions among the four spheres?
Human activities, such as deforestation and pollution, can disrupt the balance between the spheres. For instance, cutting down trees affects the biosphere and can lead to soil erosion in the geosphere, as well as changes in local weather patterns in the atmosphere.
What is the atmosphere?
The system that includes all of the layers of gasses that surround the Earth
Why is the ozone layer important?
The ozone layer protects us from harmful UV rays from the Sun. The Ozone protects us from 97% of the UV rays.
What are the parts of Earth's geosphere?
Crust, Upper Mantle, Lower Mantle, Outer Core, and Inner Core. (rocks, Mountains, soil...)
How does Earth's atmosphere protect us. What would happen if we didn't have an atmosphere?
Our atmosphere contains the air that we breathe, our atmosphere (ozone layer) protects us from the suns harmful rays, atmosphere protects us from meteors coming to Earth's surface.
How do plants in the biosphere contribute to the atmosphere?
Plants absorb carbon dioxide from the atmosphere during photosynthesis and release oxygen as a byproduct. This process is essential for maintaining atmospheric balance and supporting life.
