Earth's Systems

What are the four major systems of Earth?

• geosphere, hydrosphere, atmosphere, biosphere

• lithosphere, cryosphere, troposphere, lithosphere

How does the atmosphere protect Earth?

• Reflecting harmful solar radiation back into space

• Causing extreme weather patterns

• Creating holes in the ozone layer

• Absorbing harmful solar radiation, regulating temperature, and providing oxygen for living organisms.

Explain the role of the hydrosphere in Earth's systems.

• The hydrosphere is not connected to the biosphere

• The hydrosphere has no impact on Earth's systems

• The hydrosphere only affects the atmosphere

• The hydrosphere influences climate, supports life, affects weather, and shapes the Earth's surface.

What is the lithosphere made up of?

• Earth's crust and upper mantle

• Earth's core and lower mantle

• Earth's inner core and outer core

• Earth's atmosphere and oceans

Describe the interaction between the biosphere and other Earth systems.

• The biosphere interacts with the ionosphere, pedosphere, and asthenosphere through processes like ionization, soil formation, and mantle convection.

• The biosphere interacts with the atmosphere, hydrosphere, and geosphere through processes like photosynthesis, nutrient cycling, and weathering.

• The biosphere interacts with the thermosphere, mesosphere, and troposphere through processes like radiation, atmospheric pressure, and ozone depletion.

• The biosphere interacts with the exosphere, lithosphere, and cryosphere through processes like evaporation, erosion, and glaciation.

What is the primary source of energy for Earth's systems?

• Stars

• Moon

• Wind

• Sun

How do the Earth's systems work together to maintain balance?

• The Earth's systems are controlled by human intervention

• The Earth's systems work together through various cycles and processes to regulate temperature, distribute resources, and support life.

• The Earth's systems do not require balance to function properly

• The Earth's systems work independently and do not interact

Discuss the impact of human activities on Earth's systems.

• Human activities have a minimal impact on Earth's systems

• Human activities have a significant negative impact on Earth's systems, including climate change, loss of biodiversity, and ecosystem degradation.

• Human activities only have a positive impact on Earth's systems

• Human activities have no impact on Earth's systems

Explain the concept of Earth as a system.

• Earth as a system concept ignores the impact of human activities on the environment

• Earth as a system concept emphasizes the interconnectedness and interdependence of Earth's various components and processes.

• Earth as a system concept suggests that Earth's components operate independently of each other

• Earth as a system concept focuses only on the physical aspects of the planet

How do natural disasters affect Earth's systems?

• Natural disasters affect Earth's systems by causing physical damage, altering landscapes, disrupting ecosystems, and affecting the atmosphere and climate.

• Natural disasters have no impact on Earth's systems

• Natural disasters only affect human-made structures

• Natural disasters improve Earth's systems
