When Jane visits a beach, she notices a sea stack has formed offshore. Which of the following best describes what caused the sea stack to form?
Erosion hollowed out the rock in a seaside cliff.
Deposition moved sand from the beach into an offshore pile.
A large number of shells were carried out to sea by the waves.
Water levels rose until the sea completely surrounded a rocky section of beach.
is it a pls help me
Yes, the first choice is most likely.
Water Levels rose until the sea completely surrounded a rocky section of beach
To understand what caused the formation of a sea stack, we can examine the options provided:
1. Erosion hollowed out the rock in a seaside cliff: Erosion is the process of wearing away land or rock surfaces by natural agents such as water, wind, or ice. In this scenario, if erosion hollowed out the rock in a seaside cliff, it would leave behind a distinct structure that could potentially become a sea stack. However, this option does not mention the specific formation of a sea stack.
2. Deposition moved sand from the beach into an offshore pile: Deposition refers to the process of depositing or laying down sediment, often carried by wind or water, in a new location. While deposition could contribute to the formation of features such as sandbars or barrier islands, it would not directly lead to the creation of a sea stack.
3. A large number of shells were carried out to sea by the waves: This option suggests that the shells were carried out to sea by the waves. While shells being carried away by waves is possible, it does not specifically describe the formation of a sea stack.
4. Water levels rose until the sea completely surrounded a rocky section of the beach: This process, known as submergence, describes the rising of water levels until a rock section of the beach becomes completely surrounded. Over time, the constant wave action can erode the weak points in the rock and create a sea stack.
Based on the options provided, the most plausible cause for the formation of a sea stack would be option 4: water levels rising until the sea completely surrounds a rocky section of the beach.
