Waves crash against the shores of an island, creating beaches and gullies. in this scenario, what is the primary landform and what is the secondary landform?
a. primary landform: island, secondary landform: beach and gully
b. primary landform: water, secondary landform: beach
c. primary landform: gully, secondary landform: island and beach
d. primary landform: beach, secondary landform: island and gully

When waves crash against the shore of an island creating beaches and gullies, the primary landform is the island while the secondary landform is beach and gully.

When waves crash, onshore they can make a significant impact on the landscape by shifting entire islands of sand and carving out rocky coastlines. Storm waves can even move boulders the size of cars above the high tide line, leaving massive boulder hundreds of feet inland. Wind is not the only cause of wild waves even tsunami does. A tsunami is a wave created by a disturbance that displaces a large amount of water, like an earthquake or a landslide, and they often occur in clusters or sets.

correct answer is option a.

tropopause, stratopause and mesopause have all in common aspect that is point of maximum temperature in its layer of the atmosphere. all layers of atmosphere observe abrupt change in temperature. tropopause is the boundary between troposphere and stratosphere. stratopause is the boundary between stratosphere and mesosphere. mesopause is the boundary between mesosphere and thermosphere. these all boundaries are ranges between altitude of 0 to 80 km.
