*Is the process where by molten material (magma) are forced into the earth crust or onto the surface.
*Is the process where by molten material are both intruded into the earth crust or extruded onto the earth surface.
INTRUSIVE FEATURES (INTRUDED, ONTO)
1.BATHOLITHS
Is the large mass of magma which occur after accumutation of molten material from the base of mountain.
2.DYKES
Are formed when the molten material (magma) are cooling and solidifying across the bedding plane.
Are formed when the molten material are cooling and solidifying horizontal along the bedding plane.
Is a dome shape like a mushroom which occur when the molten material are cooling and solidifying overly.
Is a shape like soucer which formed when the molten material are increased weight over the surface causing linking of the surface.
6.PHACOLITH
Is a lense like structure which formed when the molten material or igneous rock are cooling and solidifying to the crust of the anticline or to the bottom of syncline.
1.ASH AND CINDER CONE
It formed when the molten material (Magma) are violencely eject forced out due to high pressure and mixed with ash and cinder.
It occur when the lava are liquid or viscous usually produce gentle or slopely cone for large area.
Are formed alternate layer of lava and ash after eruption of great violent and forming a small conlets.
Is the vent on the top part when lava is spread out.
5.CALDERA
Is the large creater which formed due to strong eruption found to the top part of the depression may latter filled with water from a lava.
Formed when lava flow out quickly through fissures and spread out over the surrounding country.
Minor volcanic eruption
1.GEYSERS
Is the eruption of hot water and superheated water and spread up to height of 45 meters from the earth surface.
2.HOTSPRING
Is the eruption of hot water without any explosion.
