Earth & Space
Describe the layers of the Earth
Crust, mantle, outer core, inner core
What are fossils, AND why are they important.
Fossils are preserved remains; they provide insights into past life.
Define erosion and give an EXAMPLE
Erosion is the process of soil and rock being moved; an example is riverbank erosion
What are the main components of soil?
Minerals, organic matter, water, air, and microorganisms
What is the water cycle
The water cycle is the continuous movement of water through evaporation, condensation, and precipitation
What is the difference between the inner core and outer core?
The inner core is solid, while the outer core is liquid.
How do fossils provide evidence for evolution.
They show how species change over time and adapt to environments.
What factors contribute to soil formation
Factors include weathering, organic matter, and climate.
Describe how plants and animals depend on soil
They provide nutrients, habitat, and support for growth
Name the different forms of precipitation
Rain, snow, sleet, hail
How do seismic waves help scientists learn about Earth's interior?
Seismic waves change speed and direction based on material, revealing Earth's structure.
Discuss the different types of fossils.
Types include body fossils, trace fossils, and cast/mold fossils.
Explain how water can shape the landscape
Water flows can ERODE soil and shape valleys
How does soil quality affect agricultural practices
Poor soil quality can reduce crop yields
Describe the importance of groundwater
Groundwater is vital for drinking water and irrigation
Explain how the Earth's crust is formed
The crust forms from the cooling of magma and tectonic processes.
What is the process of fossilization
Fossilization occurs when organisms are buried and mineralized over time.
Discuss the importance of conservation in preventing erosion
Conservation practices like planting cover crops prevent soil loss
Explain the relationship between soil and water conservation
Healthy soil retains water and supports plant growth
Explain how human actions can impact the water cycle
Activities like deforestation and pollution can disrupt the cycle
Compare and contrast the continental and oceanic crust.
Continental crust is thicker and less dense; oceanic crust is thinner and denser.
Analyze how studying fossils can inform us about past climates.
Studying fossils helps us understand past environments and climate change.
What is the impact of human activities on soil erosion
Urbanization and deforestation can increase erosion rates
Analyze the effects of pollution on soil health
Pollution can degrade soil quality, affecting ecosystems and agriculture
Discuss the RELATIONSHIP between the water cycle and climate change
Climate change can alter precipitation patterns and affect the water cycle
