What characteristics of sedimentary and igneous rocks allow the law of superposition to be applied easily?
The law of superposition states that in undeformed sedimentary rock layers, older layers are found beneath younger layers. This principle applies easily to sedimentary rocks because they are formed from the accumulation of sediments in horizontal layers over time, preserving a chronological order. In contrast, igneous rocks can also exhibit superposition when they form in layers, such as in volcanic deposits or lava flows. However, igneous rocks can be more complex due to intrusive formations and tectonic activity, which may disrupt the original layering.

Why does the law of superposition apply mostly to sedimentary rock?
The law of superposition applies mostly to sedimentary rocks because the law of superposition states that each layer is older than the one above it and younger than the one below it. Sedimentary rock is formed mostly by sediments which have been laid down over time, and then lithified into rock. Igneous and metamorphic rocks have different processes of formation which which are more to do with heat and pressure, and less to do with sequential deposition.
Are thunder eggs sedimentary and igneous rocks?
Thunder eggs are technically both sedimentary and igneous rocks. They are formed when gas bubbles in volcanic lava solidify and are later filled with various minerals, such as quartz. So, they have characteristics of both sedimentary (formed through deposition) and igneous (formed through cooling of magma or lava) rocks.
What 2 things are applied to igneous or sedimentary rocks that make metamorphic rocks form?
Heat and pressure are applied to igneous or sedimentary rocks to make metamorphic rocks form. Heat causes mineral grains to recrystallize, while pressure helps to rearrange the mineral structure within the rock.
Is Stonehenge a sedimentary igneous or metamorphic?
igneous
Is gypsum igneous metamorphic or sedimentary?
sedimentary
How are metamorphic and sedimentary igneous rocks formed?
Igneous- Formed from hot molten magmaSedimentary- formed from sediments piling up creating layersMetamorphic- Formed when intense heat AND pressure are applied to an igneous or sedimentary rock.

Name four types of rocks?
Igneous, sedimentary, metamorphic, and extraterrestrial.
What is the name of all three rocks sedimentary igneous and?
Sedimentary, igneous and metamorphic.
Is mudstone igneous or sedimentary?
Mudstone is sedimentary
Is made of sediments an igneous rock characteristics?
No, rocks made of sediments are called sedimentary rocks. Igneous rock comes from volcanic activity -- lava and the like.
What makes a sedimentary or igneous rock form to a metamorphic rock?
heat and pressure is applied to the rock and it becomes a metamorphic rock.
