What are volcanic necks dikes and sills?
Volcanic necks are solidified magma that fills the vent of an extinct volcano. Dikes are vertical or near-vertical rock formations that form when magma is injected into fractures and solidifies underground. Sills are horizontal rock formations created when magma is injected between layers of existing rock.
Compare and contrast dikes sills batholiths and volcano necks?
Dikes, sills, and volcano necks are intrusive igneous features formed from magma that solidified beneath the Earth's surface. Dikes are vertical or near-vertical intrusions, sills are horizontal intrusions, and volcano necks are vertical conduits that fed ancient volcanoes. Batholiths are large, deep-seated intrusive bodies that often form the cores of mountain ranges. They are generally larger in size and represent a more massive intrusion compared to dikes, sills, and volcano necks.
Lava that cuts across rock layers hardens to form a feature called?
a dike. Dikes are vertical or near-vertical igneous intrusions that cut across the existing rock layers. They form when magma is forced into fractures and then cools and solidifies underground.
What happens as a tsunami approaches shallow water near a harbour?
when a tsunami enters shallow water there is imediate danger that a tsunami is about to strike...!!(: ENJOY.
What are two examples of intrusive volcanic features?
Dikes: These are vertical or near-vertical sheet-like intrusions of magma that cut across existing rock layers. Laccoliths: These are dome-shaped intrusions of magma that push up overlying rock layers, forming a mushroom-like shape.
Why could ships face danger travelling in Antarctica?
The seas are very rough near Antarctica and there are many sheets of ice and glaciers which host potential danger in fear of crashing.
What does a beaver do when it is in danger?
If beaver sense there is danger near, they slap their tails against the water so other beavers know that danger is near, and you should get to safety.
What is the danger of getting caught in a backroller near a low-head dam?
It is a danger to get caught in a backroller near a low-head dam because the "backroller" is part of a recirculating current which can hold an you against the face of the dam. If you approach too near the "boil line", even from apparent safety downstream, the current may pull you in and you may never escape
Why are jaguars near danger?
because their to white to jump a fence to escape danger!
What are volcanic necks dikes and sills?
Volcanic necks are solidified magma that fills the vent of an extinct volcano. Dikes are vertical or near-vertical rock formations that form when magma is injected into fractures and solidifies underground. Sills are horizontal rock formations created when magma is injected between layers of existing rock.
What are dikes used for?
it is a channel along which water flows or it is a high bank built on flat land near the coast to prevent flooding by the sea, an artificial slope or wall. Holland and the low countries are famous for these constructions
What smells that may mean danger is near?
gasoline
How have dikes helped the Dutch adapt to the low elevations near the North Sea?
Dikes have been crucial for the Dutch in managing the risks associated with living in low-lying areas near the North Sea. By serving as barriers to prevent seawater from flooding inland, they protect agricultural land, homes, and infrastructure from storm surges and rising sea levels. The extensive network of dikes also allows for effective water management, enabling the reclamation of land for farming and urban development. This innovative engineering has been vital for the Netherlands' economic stability and population safety.

What is the significance of basaltic dikes in the formation of volcanic landscapes?
Basaltic dikes play a significant role in the formation of volcanic landscapes by serving as pathways for magma to move from deep within the Earth to the surface. These dikes are vertical or near-vertical intrusions of basaltic rock that cut across existing rock layers. When magma rises through these dikes and erupts onto the surface, it can create new landforms such as volcanic cones, lava flows, and volcanic craters. This process helps shape the overall topography of volcanic landscapes and contributes to the dynamic nature of Earth's geology.
Who is in danger near a volcano?
No one, unless it erupts in which case everyone is.
What kind of danger is involved living near mount etna?
death
