This top layer of soil rich in organic materials
What is ground water
What is strip mining
This mining method removed large areas of land surfaces
What is seafloor spreading
This process explains how new oceanic crust forms at mid ocean ridges
What is sedimentary rock
This rocks forms from compressed sediments over time
What is clay
The soil particle is the smallest and holds the most water
What is the water table
This is the boundary between saturated and unsaturated soil
What is subsurface mining
This type of mining is used for deep underground resources

When an oceanic plate sings beneath a continental plate
What is weathering
This process break down rocks into smaller pieces
What is soil erosion
This process occurs when water removes topsoil ,harming agriculture
What is desalination
What is acid mine drainage
This environmental issue occurs when sulfide minerals react with water and air
What is plate tectonics
This theory explains the movement of Earth lithospheric plates
What is erosion
This describes the movement of sediments by wind, water or ice
What is leaching
The downward movement of dissolved nutrients through soil is called
What is subsidence
Overuse of groundwater can cause this land-sinking effect
