What is an igneous intrusion between two sedimentary rock layers?
A laccolith is an igneous formation between two sedimentary layers
Why not use igneous rocks with relative dating?
Igneous rocks are difficult to date using relative dating because they do not contain fossils. Relative dating relies on the presence of index fossils to establish the age of rock layers, and since igneous rocks form from molten magma that solidifies quickly, they do not typically contain fossils. Additionally, igneous rocks are usually intrusive or extrusive, making it harder to determine their relative ages based on their position within rock layers.
Does basalt contain fossils?
Basalt is an igneous rock that forms from the cooling of lava, and it typically does not contain fossils. Fossils are more commonly found in sedimentary rocks where the remains of organisms are preserved in layers of sediment over time.
What three of the 4 layers of this crust are igneous material?
The layers of Earth's crust that consist mostly of igneous material are the uppermost layer, the oceanic crust, and the lowermost layer, the lower continental crust and lithospheric mantle. These layers are primarily composed of igneous rocks formed from the cooling and solidification of molten rock.
Why are igneous rocks not contain fossils?
yes
Three of the four layers of this crust are igneous material?
The lithosphere, asthenosphere, and lower mantle are the three layers of Earth's crust that contain igneous material. These layers are composed of molten rock and solidified magma from volcanic activity. The fourth layer, the crust, is primarily composed of sedimentary, metamorphic, and igneous rocks.

Does igneous rock have visible layers?
no

Does an igneous rock contain iron?
Igneous rocks can contain iron, but not all igneous rocks do. The presence of iron in an igneous rock depends on the composition of the magma from which the rock formed. Iron can be found in minerals such as magnetite, hematite, and pyroxene within certain igneous rocks.

Are igneous rocks formed by pressing layers of rocks together?
No. Igneous rock is formed from cooling lava or magma.
When layers of sediments are pressed together form.?
Igneous rock

Why are igneous rocks not contain fossils?
yes
Can sedimentary rock be changed into igneous rock?
If it is forced back into the molten layers of the Earth, then yes, it will become igneous rock.
What is igneous rock layers?
Igneous rock layers are formed from the cooling and solidification of molten rock, known as magma or lava. When magma cools beneath the Earth's surface, it creates intrusive igneous rocks, while lava that cools on the surface forms extrusive igneous rocks. These layers can vary in composition and texture, depending on the rate of cooling and the minerals present. Over time, geological processes may expose these layers, allowing them to be studied in formations such as mountains or cliffs.
