How does the age of a rock layer compare with an igneous intrusion that is through it or an igneous rock extrusion above it?
If it is above it, the rock layer came after the intrusion. if the intrusion went through the rock layer is older because they layer had to be there in order for the intrusion to go through.
What layer of the earth is composed of igneous metamorphic and sedimentary rock?
The crust.
How does each type of sedimentary rock begin?
under water when layer of minerals settle on top of one an other
What is younges t rock layer fault or igneous intrusion?
The youngest rock layer in a geological sequence is typically the one that has not been disturbed by faults or intrusions. When a fault occurs, it displaces the rock layers, indicating that the fault is younger than the rocks it cuts through. Similarly, an igneous intrusion forms when magma penetrates existing rock layers, making it younger than the surrounding sedimentary rocks. Thus, both faults and igneous intrusions are younger than the rock layers they affect.
Is sandstone limestone and shale are all examples of igneous rock?
Sandstone, Limestone and Shale are all examples of sedimentary rock, formed by layer after layer of different types of water born sediment laid down over millions of years and compressed into rock. The different types of sediment determine which type of rock is formed, obviously sand being the main component of sandstone, mud can form shale. Igneous rock is rock formed by volcanic processes, different minerals in the molten rock will determine it's type, such as granite. Metamorphic rock is the third type of rock formed by extreme pressure and heat upon sedimentary rock, marble being formed from limestone, slate from shale.
What causes igneous rocks to become sedimentary rocks?
If other layers of rock, dirt, dust, and sand are put on top of the igneous rock and the layers are compressed by their own weight, they become a single, unified layer of sedimentary rock. Simple Version: 1. Igneous rock 2. More rocks are put on the igneous rock. 3. The rock on top push down and squeeze the all of the layers into one layer.
What is the hardened layer of lava called?
The hardened layer of lava is called "igneous rock".
How does the age of a rock layer compare with an igneous intrusion that is through it or an igneous rock extrusion above it?
If it is above it, the rock layer came after the intrusion. if the intrusion went through the rock layer is older because they layer had to be there in order for the intrusion to go through.
Why did the ozone layer break?
Ozone layer break because of CFC's. they react with ozone and break it.
What layer of the earth is composed of igneous metamorphic and sedimentary rock?
The crust.
What layer of the earth is thin chemically complex?
The thinnest layer of the earth is the outer layer, or the crust. It is made up of sedimentary, metamorphic and igneous rock.
What is a hardened layer in a volcano?
As lava cools, it hardens and forms a thick layer of rock. These rocks are known as igneous rocks. An example of an igneous rock is pumice, which is used in spa treatments to soften feet.
Why do rock fossils form in sedimentary rock and not in igneous rock?
because sedimentary rocks are on the top layer, while igneous rocks are were the magma is
Is earths outer layer called deposition?
No, deposition is like accumulation, where & how sediments settle. The outer layer is the crust.
How does determining the ages of igneous rocks help to date fossils?
Determining the ages of igneous rocks helps to establish the age of the rock layer in which fossils are found. By dating the igneous rocks above and below the fossil-containing layer, scientists can narrow down the possible age range of the fossils found within that layer. This helps to provide a more accurate estimate of the fossil's age.
When ash and dust begin to settle on the ground they eventually become compacted by what?
When ash and dust settle on the ground, they can become compacted by natural processes such as wind, rain, and the weight of additional layers of sediment accumulating on top of them. Over time, these forces can squeeze the ash and dust particles together, forming a more solid layer.
Which layer of liquid would settle on the bottom of a graduated cylinder?
The layer with the highest density would settle on the bottom of a graduated cylinder, as denser liquids tend to sink below less dense liquids.
