Exploring Earth and Its Resources

What is the primary source of energy for the Earth?

• Ocean currents

• The Moon

• The Sun

• Volcanic activity

Define renewable resources and give two examples.

• Solar energy, Wind energy

• Nuclear energy

• Natural gas

• Coal energy

What is the water cycle and its main processes?

• Melting, freezing, and boiling

• Sublimation, filtration, and distillation

• The water cycle consists of evaporation, condensation, precipitation, and collection.

• Photosynthesis, respiration, and digestion

Explain the difference between weather and climate.

• Weather refers to the Earth's atmosphere; climate refers to the Moon's atmosphere.

• Weather is short-term and specific; climate is long-term and general.

• Weather is determined by human activity; climate is natural and unchanging.

• Weather is the average temperature over decades; climate is the daily forecast.

What are the layers of the Earth?

• Crust, Mantle, Outer Core, Inner Core

• Lithosphere, Asthenosphere, Mesosphere, Exosphere

• Crust, Mantle, Atmosphere, Lithosphere

• Core, Shell, Surface, Subsurface

What is the significance of biodiversity?

• Biodiversity has no impact on climate change.

• Biodiversity is only important for aesthetic purposes.

• Biodiversity is irrelevant to agricultural productivity.

• Biodiversity is significant for ecosystem health, stability, and human well-being.

Describe the impact of deforestation on the environment.

• Deforestation increases biodiversity and promotes wildlife habitats.

• Deforestation negatively impacts the environment by increasing carbon emissions, reducing biodiversity, disrupting water cycles, and causing soil erosion.

• Deforestation improves soil quality and enhances agricultural productivity.

• Deforestation has no effect on carbon emissions or climate change.

What are fossil fuels and how do they form?

• Fossil fuels are formed from volcanic activity and minerals.

• Fossil fuels are created from the decomposition of rocks and soil.

• Fossil fuels are renewable energy sources like solar and wind.

• Fossil fuels are natural resources like coal, oil, and natural gas formed from the remains of ancient organisms over millions of years through heat and pressure.

Explain the concept of sustainable development.

• Sustainable development focuses solely on economic growth.

• Sustainable development is about preserving traditional practices without change.

• Sustainable development is the practice of meeting present needs without compromising the ability of future generations to meet their own needs.

• Sustainable development prioritizes the needs of the present over future generations.

What role do oceans play in regulating the Earth's climate?

• Oceans regulate the Earth's climate by absorbing solar energy, circulating heat, and acting as carbon sinks.

• Oceans have no impact on the Earth's climate.

• Oceans only affect weather patterns in coastal regions.

• Oceans primarily serve as a source of freshwater for the land.
