Which of the following projectiles from space that when frozen, are the size of a small town?

• Asteroids

• Meteoroids

• Meteorites

• Comets

It is a natural process which shapes shorelines by the wearing away of coastal land or beaches.

• Coastal Erosion

• Sinkhole Formation

• Ground Subsidence

• Landslides

Answer explanation

Coastal Erosion is the correct choice as it refers to the natural process of wearing away coastal land or beaches.

These are cavities in the ground that form when water erodes an underlying rock layer.

• Ground Rupture

• Ground Subsidence

• Sinkhole

• Coastal Erosion

These projectiles from space are those which are still in flight in the Earth’s atmosphere and gives off a characteristic light streak.

• Meteorites

• Meteors

• Asteroids

• Meteoroids

It is the relative lowering of the Earth’s surface usually with respect to the mean sea level.

• Coastal Erosion

• Sinkhole Formation

• Ground Subsidence

• Landslides

This occurs when the land surface above collapses or sinks into the cavities or when surface material is carried downward into the voids.

• Coastal Erosion

• Ground Subsidence

• Sinkhole Formation

• Rain-fall Induced Landslides

It is the occurrence of landslide triggered by heavy rainfall which is common in grounds with steep topography.

• Coastal Erosion

• Ground Subsidence

• Sinkhole Formation

• Rain-fall Induced Landslides

These are stony, iron, and stony-iron chunks, from the asteroid belt, that are still travelling in outer space.

• Meteorites

• Meteors

• Asteroids

• Meteoroids

Answer explanation

Meteorites are stony, iron, and stony-iron chunks from the asteroid belt that have entered Earth's atmosphere, while meteoroids are similar chunks still travelling in outer space.

Humans cannot be considered as agents in speeding up the process and intensifying the effects of coastal erosion.

• TRUE

• FALSE

It is the impact of an extraterrestrial body on the surface of the earth.

• Nature Impact

• Bolide Impact

• Space Impact 

• Projectile Impact
