True or false igneous rocks are formed into layers?

No. Igneous rocks were NOT formed in layers. I took a test and they are not formed in layers. This is what the paragraph said {The Word "igneous" means made from fire or heat. All igneous rocks have been formed by heat. Deep in the earth it is very hot. The rocks and minerals there have been changed into molten rock called "magma". This hot material sometimes rises to the earths surface through fissures or cracks caused by earthquakes, volcanoes or other deep movements of the earth's crust. Igneous rocks are formed when magma cools and hardens. Scientists divide igneous rocks into two group. They are called "extrusive" rocks and "intrusive" rocks. When magma hardens below the suface of the earth, surrounded by older rocks which it has invaded, the rock is called "intusive" igeous rock. If magma reaches the surface of the earth, however, it becomes lava, and the rock is called "extusive" igneous rock. Lava is a common igneous rock. The namelava can mean molten rock or cool hard rock. The two most common and important igneous rocks are granite and basalt. Some others are diorite, felsite, pumice and obsidian.} thank you! that was fun, and your welcome. bye!

What processes can change sedimentary rock into igeous rock?

Sedimentary rock can be transformed into igneous rock through the processes of melting and solidification. When sedimentary rock is subjected to extreme heat and pressure, it can melt into magma. If this magma then rises to the surface and cools, it solidifies to form igneous rock. This transformation typically occurs in volcanic or tectonically active environments.


What process can change sedimentary rock into igeous rock?

Sedimentary rock can be transformed into igneous rock through the process of melting and subsequent solidification. When sedimentary rock is subjected to extreme heat and pressure, it can melt into magma. If this magma then rises to the surface and cools, it crystallizes to form igneous rock. This process can occur at tectonic plate boundaries or through volcanic activity.


How does igeous change to sedimentary?

Igneous rocks can change into sedimentary rocks through the process of weathering and erosion, where the igneous rocks are broken down into smaller sediments. These sediments are transported and deposited in layers, then compacted and cemented together over time to form sedimentary rocks. This process involves the transformation of the original igneous rock into a new type of rock through the deposition and lithification of sediments.


What are igeous rocks that are light colored and have a lower density they form from thick stuff magma that contains lots of silica and lesser amounts of iron and magnesium?

Those igneous rocks would be referred to as felsic.
