When magma flows horizontally along rock layers, it can form a feature called a sill. Sills are tabular igneous intrusions that are parallel to the surrounding rock layers. They are typically formed when magma is injected between existing rock layers and cools and solidifies underground.

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.
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.
Of the three primary forms of subaerial volcanoes consist of alternating layers of tephra and solidified lava?
The three primary forms of subaerial volcanoes are stratovolcanoes, shield volcanoes, and cinder cone volcanoes. Stratovolcanoes are characterized by alternating layers of tephra and solidified lava due to their explosive eruptions and lava flows. Shield volcanoes have gentle slopes formed from successive lava flows with occasional tephra layers. Cinder cone volcanoes are small, steep-sided volcanoes made up almost entirely of tephra fragments from explosive eruptions.
Magma that hardens vertically underneath the surface will form a sill?
Yes, that's correct. Sills are igneous rock formations that form when magma is intruded horizontally between rock layers and then solidifies underground. If the magma solidifies vertically underneath the surface, it will create a sill structure.
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 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.
