Earth's Spheres
What is the biosphere?
The Earth system that includes all living things. (plants, animals, humans)
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, Inner Core.
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 Geopshere?
The Earth system that includes all non-living things (rocks, minerals, sediments ,etc.)
What is the lowest layer of the atmosphere?
The troposphere is the lowest layer of the atmosphere.
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 geosphere & hydrosphere interact?
Geosphere depends on water for soil, geosphere is eroding and weathered due to rain, lakes, oceans.
What is the hydrosphere?
The system that includes all of the water on, under or above Earth
What is a sphere that you have an interdependent (Attached) relationship with?
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.
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.
In what way do human activities impact the biosphere and hydrosphere?
Human activities can pollute water sources, affecting the biosphere's health and biodiversity.
What is a system?
A collection of parts that are working together.
What layer of Earth's atmosphere do we live on?
The Troposphere
Earth has 4 systems. Which system has many landforms?
Geosphere
Why is the Greenhouse Effect bad for Earth?
Leads to flooding, glaciers melt, evaporating of habitats (ponds, lakes, etc.) , plants/animals can die in extreme heat.
What is the atmosphere?
The system that includes all of the layers of gasses that surround the Earth
When a volcano erupts how does the ash from the eruption interact with the hydrosphere, atmosphere and biosphere?
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.
Provide an example of how the atmosphere influences the biosphere.
The atmosphere provides carbon dioxide, which plants use for photosynthesis.
How do the biosphere and hydrosphere interact?
The biosphere depends on the hydrosphere for water, which is crucial for all living organisms.
