Earth's Structure
What are the three major compositional zones of Earth's interior?
The three major compositional zones of Earth's interior are the crust, mantle, and core.
What is the definition of the atmosphere?
The atmosphere is the layer of gases that surrounds the Earth.
What is the first law of thermodynamics?
The first law of thermodynamics states that energy cannot be created or destroyed, only transferred or transformed.
What is the definition of an ecosystem?
An ecosystem is a community of living organisms and their interactions with the abiotic environment.
How thick is the oceanic crust?
The oceanic crust is approximately 6-11 kilometers thick.
What percentage of Earth's surface is covered by water?
Approximately 71% of Earth's surface is covered by water.
How does energy enter the Earth system?
Energy enters the Earth system through solar radiation
What are producers and what is their source of energy?
Producers are organisms that can convert sunlight into energy through the process of photosynthesis. Their source of energy is the sun.
What is the main element that makes up Earth's core?
The main element that makes up Earth's core is iron.
What is the definition of the geosphere?
The geosphere refers to the solid, rocky part of Earth's surface.
What is the definition of carrying capacity?
Carrying capacity is the maximum number of individuals an environment can support sustainably.
How does an ecosystem respond to environmental change?
Ecosystems can respond to environmental change through adaptations, migration, or changes in population dynamics.
What are the five major structural zones of Earth's interior?
The five major structural zones of Earth's interior are the lithosphere, asthenosphere, mesosphere, outer core, and inner core.
Where can phosphorus be found in the phosphorus cycle?
Phosphorus can be found in rocks, soil, and sediments in the phosphorus cycle.
How does a food chain differ from a food web?
A food chain is a linear sequence of organisms where each organism is eaten by the next, while a food web is a complex network of interconnected food chains.
How does energy flow through an ecosystem?
Energy flows through an ecosystem in a one-way direction, from producers to consumers.
How thick is the asthenosphere?
The asthenosphere is approximately 100-350 kilometers thick.
What is the process that changes water from liquid to water vapor?
The process that changes water from liquid to water vapor is called evaporation.
How does human activity affect the carbon cycle?
Human activity affects the carbon cycle through activities such as burning fossil fuels and deforestation, which release carbon dioxide into the atmosphere.
What is the relationship between Earth's systems and ecological balances?
Earth's systems and ecological balances are interconnected, as changes in one system can have impacts on the others, and maintaining ecological balances is crucial for the overall health and stability of the planet.
