What type of plate is plate a what about plate b why do you say so brainly?
Answers
In science 10 unit 1 module 1 activity 3 , the title of the activity is " Head-On Collision" Part A: Converging continental plate and Oceanic plate. This activity shows the different geological features formed in convergent boundary particularly in converging continental plate and oceanic plate. The activity presented a picture in which plate B subducted beneath plate A. Plate B is an oceanic plate which is denser than plate A which is another oceanic plate but having lesser density compared to plate B.
Q15. What type of plate is plate A ? what about B ? why do you say so ?
Answer:
Plate A is an oceanic plate because it is relatively thinner compared to plate B. While Plate B is a continental plate because it is thicker and floats higher than the other plate. Oceanic plate is denser compared to continental plate, which you can see in the picture denser plate A will subduct beneath less dense plate B.
Lithosphere
Is the rock portion of the earth. It is composed of the crust and the upper mantle which are both solid that are made up of rocks. Tectonic plate are also called as lithospheric plate.
Two Types of Lithospheric Plates
Oceanic Plate
Continental Plate
Oceanic Plate
Are thinner and have a higher density compared to continental plate. Examples are: Pacific plate, Antarctic Plate
Continental Plate
Thicker and have a lesser density compared to oceanic plate. Examples are: Eurasian plate, African plate, North American plate, South American plate, Australian plate.
Three types of Convergent boundary
Continental to oceanic convergence
Oceanic to oceanic convergence
Continental to continental convergence
Continental to oceanic convergence
Oceanic plate will subduct beneath the continental plate since it is more denser. Several geological features will formed because of this convergence. Philippine Islands are also a product of continental to oceanic plate convergence, wherein Eurasian plate collides with Philippine sea plate which produces volcanic islands creating Philippines Island.
Oceanic to oceanic convergence
The geological features formed in this convergence is similar to continental oceanic convergence.
Continental to continental convergence
This type of collision will not produce a trench and volcanoes, but it produces mountain ranges and earthquake. Earthquake will occur in all type of converging plates.
