What happens when magma flows in a horizontal direction along rock layers?
The magma forms sills and magma chambers.
What forms when the rock layers slip or slide along the crack?
A fault forms when rock layers slip or slide along a crack. This movement can create an earthquake if the stress becomes too great for the rocks to hold their position.
What is an igneous intrusion that forms between two layers of sedimentary rock?
An igneous intrusion that forms between two layers of sedimentary rock is known as a "sill." Sills occur when molten magma intrudes horizontally between existing rock layers, solidifying into igneous rock as it cools. This process can create distinctive geological features and may alter the surrounding sedimentary layers through heat and pressure. Sills often exhibit a uniform thickness and can vary in composition, depending on the magma source.
Are extrusions older or younger than rock layers they cut throgh?
Extrusions are younger than the rock layers they cut through. This is because extrusions, such as volcanic lava flows, occur after the formation of the existing rock layers. When molten rock erupts and flows over the surface, it solidifies and forms new material that overlays the pre-existing layers. Thus, the relationship in geological time indicates that extrusions are a more recent event compared to the older rock formations they penetrate.
Does lava follow the law of superposition?
Lava does not follow the law of superposition. The law of superposition applies to sedimentary rock layers, where older layers are typically found below younger layers due to the principle of original horizontality. Lava flows do not adhere to this principle as they can be deposited on top of existing layers regardless of their age.
This forms when magma flows in a horizontal direction along rock layers?
A dike is formed when magma intrudes and solidifies in a vertical or near-vertical orientation within pre-existing rock layers. Lava flows, on the other hand, occur when magma erupts onto the surface and flows horizontally along the ground.
What happens when magma flows in a horizontal direction along rock layers?
The magma forms sills and magma chambers.
What moves water horizontally?
A surface current is a wind-powered current that moves water along horizontally. Because the wind is on the surface, a surface current only forms along the first few hundred feet of ocean water.
What forms when magma flows in a horizontal direction?
When magma flows horizontally, it can form igneous rock formations called dikes or sills. Dikes are vertical intrusions, while sills are horizontal intrusions. These structures are formed when magma solidifies within preexisting rock layers.
What forms when the rock layers slip or slide along the crack?
A fault forms when rock layers slip or slide along a crack. This movement can create an earthquake if the stress becomes too great for the rocks to hold their position.
What forms when lava flows horizontally across a layer of rock?
When lava flows horizontally across a layer of rock, it can form a flat, expansive volcanic plateau known as a lava plateau or lava plain. This occurs when the lava spreads out and solidifies over a large area, creating a relatively flat surface with a thick layer of cooled lava.
What type of layers and mountains that AA and Pahoehoehoe forms?
AA lava flows look like broken glass and make you say "Ow Ow" when you walk across it barefoot.Pahoehoe lava flows look like pillows.
When lava flows out of cracks in a certain area the layers of lava can build up over time forming what?
Lava forms island, land, & shiny rocks
How a fossil forms in sediment?
When a river flows into a lake or ocean, the sediments that the river carries settle to the bottom. Layers of sediment may covor the dead organism.
What is an igneous intrusion that forms between two layers of sedimentary rock?
An igneous intrusion that forms between two layers of sedimentary rock is known as a "sill." Sills occur when molten magma intrudes horizontally between existing rock layers, solidifying into igneous rock as it cools. This process can create distinctive geological features and may alter the surrounding sedimentary layers through heat and pressure. Sills often exhibit a uniform thickness and can vary in composition, depending on the magma source.
What is a horizontal intrusive igneous body that forms between sedimentary rock layers?
A sill is a horizontal intrusive igneous body that forms between sedimentary rock layers. Sills are formed when magma intrudes parallel to the layering of the surrounding rocks and solidifies underground.
Does lava follow the law of superposition?
Lava does not follow the law of superposition. The law of superposition applies to sedimentary rock layers, where older layers are typically found below younger layers due to the principle of original horizontality. Lava flows do not adhere to this principle as they can be deposited on top of existing layers regardless of their age.
