The last answer
Explanation:
The sun is a perpetual resource because solar radiation steadily streams from the sun without interruption and is expected to do so for the next 6 billion years.
What do you mean by perpetual resource?Perpetual resources are those that last forever like solar energy and wind. Non-renewable resources, once extracted completely from a given area, will never be available in the same spot again (except after millions of years).
Perpetual resources are natural resources—such as solar energy, wind, and tides—that have no chance of being used in excess of their availability. They can be used for power generation and conversion to electric energy.
Sunlight, wind, geothermal heat, tides, and flowing water are perpetual resources. On Earth, there are only limited amounts of fossil fuels such as oil, coal.

b. It is a new field of ocean science.
c. The ocean releases one quarter of the carbon dioxide in the atmosphere.
d. All of the above
Answers
Answer:
d. All of the above
Explanation:
All of the given choices are reasons to study the ocean carbon cycle. The ocean occupies about 70% of the earth surface area and it plays important roles in carbon cycling.
The ocean acts as reservoir for carbon in many different ways especially due to the dissolution of this gas in it. It also releases a significant amount of carbon dioxide to the atmosphere due to the plethora of life within it. The field is also relatively new and more works must be done to understand this cycle.Answer:

If humans change the function or equilibrium of one of Earth's systems, this will not change
the function or equilibrium of all of Earth's systems.
True
False
Answers
Answer:
False.
Explanation:
All of the things found in the Earth system can be categorized into four (4) main categories and these includes;
I. Land: this subsystem forms a sphere which is generally referred to as litosphere.
II. Water: this subsystem forms a sphere which is generally referred to as hydrosphere. It comprises of landforms such as mountains, valleys, plateaus, ridge, rocks, etc.
III. Air: this subsystem forms a sphere which is generally referred to as atmosphere. This sphere comprises of gases such as oxygen, carbon dioxide, nitrogen, etc.
IV. Living organisms: this subsystem forms a sphere which is generally referred to as biosphere. It comprises of all living things such as humans, animals and plants.
If humans change the function or equilibrium of one of Earth's systems, this will significantly change the function or equilibrium of all of Earth's systems. Consequently, these changes result in environmental phenomenon such as volcanoes, earthquakes, tornadoes, wildfire, etc.
