What do all planets have in common?
They orbit the sun
What process forms sedimentary rock?
Compaction and cementation
What type of boundary creates new crust?
Divergent boundary
What is climate?
Long-term weather patterns
What is one renewable resource?
Solar, wind, or water
Why do seasons differ by hemisphere?
Tilt and orbit
How does technology help space study?
Better data/images
Why are gas giants different from rocky planets?
Composition and size
How can one rock type become another?
Through the rock cycle (heat, pressure, weathering)
Why do volcanoes often form near plate boundaries?
Because of magma movement from plate interactions
Why do coastal areas have milder climates?
Water heats and cools slowly
How does deforestation affect ecosystems?
Loss of habitats and biodiversity
What would happen without Earth’s tilt?
Seasons would not occur
Why is scientific knowledge always changing?
New evidence updates models
What would happen if Earth were closer to the sun?
Higher temperatures, possible loss of life-supporting conditions
Why are some natural resources nonrenewable?
They take millions of years to form
How does seafloor spreading support plate tectonics?
Shows new crust forming and plates moving apart
How does uneven heating drive global wind patterns?
Creates pressure differences that move air
How can communities reduce environmental impact?
Sustainable practices like recycling and conservation
Explain how rotation AND revolution work together to affect life.
Controls time, seasons, climate patterns, ocean tides
Why did scientists change from the geocentric to heliocentric model?
New evidence and better observations
Which planet besides Earth is MOST likely to support life and why?
Mars
What drives the rock cycle?
Heat, pressure, weathering/ erosion
Predict what happens when two continental plates collide.
Mountain formation
What causes wind?
Pressure differences
What is an example of a nonrenewable resource?
Coal, fossil fuels, oil
