Energy sources
What process allows single-cell algae to consume carbon dioxide and emit oxygen?
Photosynthesis
What is the significance of the ecological footprint?
Ecological footprint measures land/water needed to support consumption and waste.
How do GMO crops help with global food productions?
GMO crops can grow in new places and resist pests, increasing food production
Why do tectonic plates move?
Tectonic plates move due to convection currents in the Earth's mantle
What are two advantages of using sustainable energy?
Advantages include reducing pollution and providing renewable energy sources
What is a major environmental challenge associated with hydropower?
Hydropower can disrupt river ecosystems and fish migration
Why is soil maturity important for agriculture?
Mature soil holds nutrients better and supports healthy crops
What is the difference between renewable and non-renewable resources?
Renewable resources can be replenished; nonrenewable resources cannot keep up with use and take a long period of time to replenish
What evidence did Alfred Wegener use to support continental drift?
Mesosaurus fossils found on separate continents suggest continents were once connected.
Why are some energy sources considered sustainable?
Because they replenish naturally and have low environmental harm
Plates move towards each other at which boundary?
Convergent
How does deforestation impact biodiversity?
Deforestation reduces habitats, causing loss of species diversity
What is the difference between organic and conventional agriculture?
Organic agriculture avoids synthetic chemicals; conventional uses them.
How does soil composition affect plant growth (explain)
Soil with balanced sand, silt, and clay holds water and nutrients well for plants
Why is ecological footprint important in environmental science?
Ecological footprint shows human impact on Earth's resources.
How does hydropower generate electricity?
Hydropower uses flowing water to turn turbines generating electricity
True or False
wind power can be noisy and considered an eyesore.
True
What is one environmental impact of the Green Revolution (explain)
The Green Revolution increased yields but caused soil depletion and pollution
What causes earthquakes in transform plate boundaries?
Earthquakes occur at transform boundaries due to plates sliding past each other
How can solar panels contribute to reducing carbon emissions?
Solar panels generate clean electricity, reducing fossil fuel use
Which technology primarily harnesses solar energy?
Photovoltaic cells
Why might wind power be considered a noise disruption?
Wind turbines produce sound that can disturb nearby residents
What roles do convection currents play in plate tectonics?
Convection currents in the mantle cause plates to move by pushing and pulling them.
What is the significance of the rock cycle in Earth's geology?
The rock cycle shows how rocks change form, shaping Earth's surface
Why is it important to restore abandoned mines?
Restoring mines prevents pollution and soil degradation.
