<span>the answer is physical boundary</span>
Answer:
a. True.
b. False.
c. True.
d. True.
Explanation:
A landform refers to a geomorphic or natural feature of the Earth's surface, which typically makes its terrain. Some examples of landforms on planet earth are mountain, plains, volcanoes, valley, hills and plateau.
Basically, the tectonic plates such as the oceanic and continental lithosphere interact in three (3) ways and these are; divergent, transform and convergent boundaries.
a. Plates shift the continents around as they move, so Earth's surface is constantly changing.
b. False: the contacts between plates are called passive margins. A passive margin is a region where continents have rifted apart and are then separated by a body of water such as an ocean.
c. True: plates may consist of both ocean floor and continental crust, but never just oceanic or continental crust.
d. True: there are 120 major tectonic plates.
The compound of an amino acid there are 20 in total some of amino acid include serine, lysine, leucine, proline, and valine. Hopes this helps!!!!
The coolest layer is the crust. The crust is on the surface of the earth (where we are) . Inner Core
The correct is - (b) the African plate is spreading apart to form two separate plates.
The African tectonic plate, on of the biggest ones, but it will not be like for a long time in the future as the plate is separating into two parts. The eastern part of the plate is moving towards east, and it is moving away from the mainland Africa. Because of this movement, cracks have been forming all over the eastern side of Africa, thus the numerous faults. Over time, as the distance is increasing, the space in between will fill with ocean water, thus making a natural barrier between them, as well as setting the foundations for the creation of a new sea, or maybe even an ocean.
