Answer

Brief Explanations:

  1. Igneous rocks form from cooling and solidifying magma or lava.
  2. The rock - cycle involves sedimentary rocks formed from sediments, metamorphic rocks from existing rocks under heat and pressure, and igneous rocks from magma/lava.
  3. Igneous rocks with large crystals form when magma cools slowly beneath the Earth's surface, while those with small crystals form when lava cools quickly on the surface.
  4. Shale and limestone are sedimentary rocks, indicating past environments with sediment deposition, like shallow seas or lakes.
  5. A rock made of small grains stuck together is likely a sedimentary rock.
  6. Granite is an igneous rock formed from cooling magma. Shale is sedimentary, marble is metamorphic, and limestone is sedimentary.

Answer:

  1. Igneous rocks are formed when magma (molten rock beneath the Earth's surface) or lava (molten rock on the Earth's surface) cools and solidifies.
  2. The rock cycle is a continuous process. Sedimentary rocks are formed from the accumulation and compaction of sediments. Metamorphic rocks are created when existing rocks are subjected to high - heat, high - pressure, or chemically active fluids. Igneous rocks form from the cooling and solidification of magma or lava. These rocks can be broken down into sediments to form sedimentary rocks again, or be transformed into metamorphic rocks, and magma can cool to form igneous rocks, creating a cycle.
  3. Igneous rocks with large crystals form when magma cools slowly deep within the Earth's crust, allowing enough time for large crystals to grow. Igneous rocks with small crystals form when lava cools quickly on the Earth's surface, so there is less time for crystal growth.
  4. Since shale and limestone are sedimentary rocks, it can be inferred that the landscape has likely been through periods of sediment deposition, such as in shallow seas or lakes, followed by compaction and cementation to form these sedimentary layers.
  5. You are probably looking at a sedimentary rock, as sedimentary rocks are often composed of small grains (sediments) that are stuck together through compaction and cementation.
  6. C. Granite. Shale is a sedimentary rock formed from clay - sized sediments. Marble is a metamorphic rock formed from limestone or dolomite. Limestone is a sedimentary rock formed from the accumulation of calcium - carbonate rich materials. Granite is an igneous rock that forms from the slow cooling of magma beneath the Earth's surface.
