People build jettys for a variety of reasons. One of the most common is to protect the beach from smaller waves and currents that can erode the beach shoreline.
Jettys are also commonly built as an entryway to a marina, to keep the waterway deep enough for boats to navigate through. Additionally, jettys are sometimes used to create a funnel for currents to carry sediment and sand to a specific place, such as a beach, to replenish lost sand contributing to beach nourishment.
Finally, jettys may also be used to keep birds away from beachgoers - for example, in areas where seagulls may try to steal food from sunbathers. As such, while jettys can have negative effects on beach nourishment, they may have positive impacts in other areas which make them worth the risk.

imilarities exist between the composition of isotopes in rocks from Earth’s mantle and rocks from two different types of meteorites. Scientists have also found evidence that materials both with and without volatile compounds (such as water) were involved in Earth’s formation.
Did Earth most likely form through a uniform (homogeneous) or varied (heterogeneous) process of accretion? Use evidence to support your answer.
Earth most likely formed through a heterogeneous process of accretion, as evidenced by isotopic similarities with meteorites and the presence of both volatile and non-volatile materials.
The evidence suggests that Earth most likely formed through a varied (heterogeneous) process of accretion. Isotopic similarities between rocks from Earth's mantle and rocks from two types of meteorites, called carbonaceous chondrites and enstatite chondrites, indicate a shared origin. This indicates that material from these meteorites was incorporated into Earth during its formation.Additionally, the presence of both volatile and non-volatile compounds in Earth's composition provides further evidence of a varied accretion process. Volatile compounds, such as water, were present in Earth's formation. This is supported by the detection of water in minerals found in Earth's mantle and the presence of water on its surface.On the other hand, non-volatile compounds like metals and silicate minerals were also part of Earth's composition. These materials likely originated from different sources and were accreted together during the formation process.Therefore, the isotopic similarities with different types of meteorites and the presence of both volatile and non-volatile compounds strongly support the hypothesis that Earth's formation involved a varied and heterogeneous process of accretion.For more such question on accretion

Which of the following ways can climate change impact agricultural production? (select all that apply) o Exposure of crops in coastal regions to salt water, as sea levels rise
o Agricultural posts spread to new regions as climate warms, affecting crops and Tvestock o More extreme rainfall can lead to increased soil erosion o Increased carbon dioxide levels can slow down the process of photosynthesia
Climate change can have a number of negative impacts on agricultural production.
Firstly, exposure of crops in coastal regions to salt water, as sea levels rise, could render these crops unsuitable for consumption. Secondly, agricultural posts spread to new regions as climate warms, may affect the crops and livestock due to attributes of this new environment that may be unsuitable.
Thirdly, more extreme weather patterns, particularly those involving increased rainfall, can lead to increased soil erosion which in turn leads to fewer nutrients available to plants and crops in the substrate. Finally, increased carbon dioxide levels can slow down the process of photosynthesis, which could lead to lower yields in crops and livestock. All of the above scenarios can lead to lower agricultural production and have economic ramifications.

How does a sea breeze form? How does a sea breeze form? Because the land heats more slowly during the day than does the sea, winds blow to the sea from the land. Because the land heats as quickly during the day as the sea, winds blow to the land from the sea. Because the land heats more slowly during the day than does the sea, winds blow to the land from the sea. Because the land heats more quickly during the day than does the sea, winds blow to the sea from the land. Because the land heats more quickly during the day than does the sea, winds blow to the land from the sea.
Answer:
Because the land heats more quickly during the day than does the sea, winds blow to the land from the sea.
Explanation:
In summary, we can confirm that the sea breeze happens as a result of the temperature difference and uneven heating rates between the winds on land and at sea. The land heats up faster than sea water. In this case, as the air that flies over the earth gets hotter and hotter, the winds above the sea are cold and due to the temperature gradient they tend to leave the sea and invade the land, replacing the warm air and decreasing the imbalance between temperatures. In this way, the sea breeze is created.

which of the following is not found in an area of alpine glaciation?
A. V-shaped valleys
B. aretes
C. cirques
D. U-shaped valleys
V-shaped valleys are not found in an area of alpine glaciation.
The correct answer is "A".
Alpine glaciation refers to the process of glacial erosion and deposition in mountainous regions. It is characterized by the formation and movement of glaciers, which shape the landscape through the process of erosion. The options provided are all landforms commonly associated with alpine glaciation, except for V-shaped valleys. V-shaped valleys are typically formed by the action of rivers and are characterized by steep sides and a narrow bottom.
In contrast, alpine glaciation tends to create U-shaped valleys, which have a broad, U-shaped cross-section resulting from the glacial erosion and the smoothing of the valley floor. Aretes, which are narrow ridges between two glacial valleys, and cirques, which are bowl-shaped hollows at the head of a glacier, are landforms commonly found in areas of alpine glaciation.
The correct answer is "A".

A thunderstorm that produces 0.25 inches of rain poses no threat to starting a fire.
a. true
b. false
Answer:
b. false
Explanation:
While 0.25 inches of rain may provide some moisture to the environment, it is rarely enough to eliminate the risk of a fire starting. Factors such as vegetation dryness, humidity levels, wind conditions, and the presence of flammable materials all play essential roles in determining fire risk. Even if a thunderstorm produces some rain, it does not guarantee complete safety from fire ignition. Multiple factors and local conditions must be considered to assess the fire risk accurately.
