• island crust

• coastal crust

• continental crust

• earth's crust

In the area where two plates converge, several phenomena occur. One example of that phenomenon is except

• the presence of volcanic activity, intrusion and extrusion

• earthquake activity at the seabed and its surroundings

• the stretching of plates accompanied by growth at both edges of the plates

• the formation of ocean floor ridges along the plate stretching

• deep-sea volcanic activity producing pillow lava and fluid lava

The formation of mushroom rocks is caused by

• the fossil of animals and plants continuously decomposing

• prolonged dry season

• erosion of rocks by wind

• wave impact

• river erosion around it

The landform in the form of a valley occurs due to the folding process called

• Anticline

• Syncline

• Horst

• Graben

• Fault

The tectonic event in the form of orogeny can produce landforms in the form of

• deeper ocean trenches in Sulawesi

• uplift of coral islands in the South Pacific

• terraced coastal plains in East Timor

• karst landforms in Gunung Kidul

• the formation of the Semangko Fault in Sumatra

The earthquake that occurs due to volcanic processes is called
