• What is the rock cycle?

  The rock cycle is a continuous process of transformation between igneous, sedimentary, and metamorphic rocks.

• What are the three main types of rocks in the rock cycle?

  • Igneous rocks
  • Sedimentary rocks
  • Metamorphic rocks
  geology rocks
• What process transforms igneous rocks into sedimentary rocks?

  Weathering and erosion followed by sedimentation.
  geology rock_cycle
• What is the process that turns sedimentary rocks into metamorphic rocks?

  Metamorphism due to heat and pressure.
  geology rock_cycle
• What is the role of heat in the rock cycle?

  Heat causes metamorphism and melting of rocks, leading to the formation of igneous rocks.

• What is the role of pressure in the rock cycle?

  Pressure contributes to the formation of metamorphic rocks from sedimentary and igneous rocks.

• Which type of rock is formed from cooled magma or lava?

  Metamorphic rocks

  Fossil rocks

  Igneous rocks

  Sedimentary rocks
  geology rocks
• Which process involves the accumulation of sediments?

  Lithification

  Sedimentation

  Erosion

  Metamorphism
  geology rock_cycle
• The rock cycle includes processes such as weathering, erosion, and sedimentation.
  geology rock_cycle
• The transformation of rocks is a continuous process known as the rock cycle.
  geology rock_cycle
• Metamorphic rocks can be formed from both igneous and sedimentary rocks under heat and pressure.
  geology rock_cycle
• The three main types of rocks in the rock cycle are igneous, sedimentary, and metamorphic.

• What is magma?

  Hot (melted) molten rock that forms into solid rock when cooled. Found under the crust layers of Earth.
  geology magma
• What is lava?

  Refers to magma when it explodes out of a volcano or cracks at the surface. Found on the Earth's surface.
  geology lava
• Where is magma found?

  On the Earth's surface

  Under the crust layers of Earth

  In oceans

  In the atmosphere
  geology magma
• What does lava refer to?

  Magma underground

  Magma that erupts from a volcano

  Solid rock

  Ash clouds
  geology lava
• The process of magma cooling forms solid rock. It is found under the crust layers of Earth.
  geology magma
• Lava is magma that erupts out of a volcano or cracks at the surface, and it is found on the Earth's surface.
  geology lava
• What happens to magma when it cools?

  It forms into solid rock.
  geology magma
• What happens to lava after it erupts?

  It cools and solidifies on the Earth's surface.

• What is depicted in the diagram?

  A volcano erupting, showing magma underground, lava flowing, and smoke/ash clouds above.
  geology volcano
• Why is there no actual photo of magma?

  Magma is located beneath the Earth's surface, making it impossible to capture a direct photo of it.
  geology magma
• What is the main difference between lava and magma?

  Lava contains more gas than magma.

  Lava is cooler than magma.

  Lava is solid, magma is liquid.

  Lava is above ground, magma is below ground.

• What does lava look like?

  Lava is typically red or orange when flowing, glowing brightly against a dark landscape.
