What atmospheric layer contains the ozone layer, which protects life on Earth from harmful ultraviolet rays?
What is the stratosphere?
The movement of sediments from one place to another
What is erosion?
What is the process by which excess nutrients, often from fertilizers, cause algae blooms in aquatic ecosystems?

What is the outer core?
What is the name of the plastic layer on which tectonic plates sit?
What is the asthenosphere?
What is the term for the breakdown of rock into smaller pieces through chemical, physical, or biological processes?
What is weathering?

What is the shape of the earth/the Coriolis effect?
2 types of weathering
answers vary!
What is the layer of the atmosphere in which weather occurs?
What is the troposphere?
The driver of tectonic plate movement
What are convection currents in the asthenosphere?
What process involves the downward movement of dissolved materials through the soil, often leading to nutrient depletion?
What is leaching?
What is the phenomenon where warm, nutrient-poor water displaces cold, nutrient-rich water along coastlines, disrupting marine ecosystems?
What is El Niño?
What is the term for the underlying layer of rock or sediment from which soil is formed?
What is parent material?
A farming community is facing soil degradation due to excessive irrigation, leading to salinization and reduced crop yields. Which specific soil management practices could be implemented to prevent further damage and restore soil health?
What are practices such as crop rotation, the use of organic fertilizers, mulching, and proper irrigation techniques like drip irrigation to reduce salinization?
