1.1.3 The Lithosphere

• What is the lithosphere composed of?

  Crust and upper mantle
• What are the two types of crust in the lithosphere?

  Oceanic and continental
• The continental crust is primarily composed of granite
• When two plates collide, it can lead to the formation of mountains
• The lithosphere is divided into large tectonic plates.


  True
• What are the two main layers of the lithosphere?

  Crust and upper mantle
• Oceanic crust is primarily composed of basalt
• The lithosphere is composed of the crust and the upper mantle
• Continental crust is thicker than oceanic crust and primarily composed of granite
• Plate tectonics involves the interaction of moving tectonic plates
• Plate convergence can lead to the formation of volcanic arcs


  True
• The lithosphere's rock composition influences the chemical composition of water bodies
• The lithosphere provides the foundation and nutrients for terrestrial ecosystems through soil formation
• The oceanic crust is primarily composed of basalt
• The upper mantle is part of the tectonic plates.


  True
• What is the average thickness of oceanic crust?

  5-10 km
• What is the theory that explains the movement of tectonic plates?

  Plate tectonics
• What is created when two plates move apart?

  Mid-ocean ridge
• Oceanic crust is denser than continental crust because it is composed of basalt
• Processes shaping the lithosphere:

  1️⃣ Plate Tectonics

  2️⃣ Plate Convergence

  3️⃣ Plate Divergence

  4️⃣ Plate Transform
• The upper mantle is rigid and forms part of tectonic plates


  True
• The crust's composition varies: oceanic crust is primarily basalt
• Arrange the key processes shaping the lithosphere in a logical sequence

  1️⃣ Plate Tectonics

  2️⃣ Plate Convergence

  3️⃣ Plate Divergence

  4️⃣ Plate Transform
• At mid-ocean ridges, magma rises to form new oceanic crust
• The lithosphere's topography influences atmospheric circulation patterns

  True
• Tectonic activity shapes the physical geography of the hydrosphere
• The lithosphere's mineral resources are essential for human civilization
