a. Phytoplankton grow and reproduce: add O₂ - Phytoplankton are photosynthetic organisms that require oxygen for their growth and reproduction. During photosynthesis, they release oxygen into the water, increasing the oxygen levels.
b. Summer sun warms the surface water: remove O₂ - Warmer water holds less dissolved oxygen than colder water. As the surface water gets warmer during summer, the oxygen dissolved in the water decreases, resulting in a decrease in oxygen levels.
c. Wind produces whitecaps on sea surface: add O₂ - When wind produces whitecaps on the sea surface, it increases the turbulence and mixing of air and water. This mixing introduces more oxygen into the water, increasing the oxygen levels.
d. Sewage spill produces rapid bloom of algae: remove O₂ - Sewage contains organic matter that serves as a nutrient source for algae. When there is a rapid bloom of algae, they consume oxygen during their decomposition process, leading to a decrease in oxygen levels in the water.
Overall, these scenarios highlight the dynamic nature of oxygen levels in seawater, with various factors influencing its addition or removal.

What do developing countries rely on?
Developing countries typically rely on a combination of factors to support their economic and social development.
These factors can vary depending on the specific country and its unique circumstances, but there are some common elements that are often crucial for their growth.
Firstly, developing countries heavily rely on natural resources such as minerals, oil, and agricultural products. These resources are often significant sources of export revenue and foreign exchange earnings, which contribute to their economic development.
Secondly, labor-intensive industries play a vital role in developing countries. With a large population and often low labor costs, these countries can attract industries such as manufacturing, textiles, and outsourcing services. This provides employment opportunities and contributes to their economic growth.
Additionally, developing countries rely on foreign aid and investment to finance infrastructure projects, education, healthcare, and poverty alleviation programs. Aid and investment from international organizations, bilateral partnerships, and foreign companies can help bridge the financial gaps and accelerate development.
Moreover, remittances from overseas workers are a crucial source of income for many developing countries. Money sent back home by migrant workers helps to alleviate poverty, support local businesses, and boost consumption.
Finally, developing countries often strive to develop their human capital through education and skills training. Investing in education helps create a skilled workforce, enhances productivity, and fosters innovation, driving economic growth and reducing dependence on external resources.
In summary, developing countries rely on a combination of natural resources, labor-intensive industries, foreign aid and investment, remittances, and human capital development to support their economic and social development. These factors work together to promote sustainable growth and improve the living standards of the population.

Explanation:
By definition, two shapes are congruent if you can map one onto the other using rigid transformations (a sequence of one or more rotations, translations, and reflections). Since any sequence of rigid transformations performed on a triangle result in a congruent triangle, what does that imply about the corresponding side lengths and angle measures for two congruent triangles?
When two triangles' matching sides and angles are of equal length, two triangles are said to be congruent.
If the matching angles and sides of two triangles are congruent, then two triangles were said to have been comparable.
What is congruence?Two figures or objects are said to be congruent in geometry if they are the same size and shape, or if one is the mirror reflection of the other.
Formally speaking, two sets of points are said to be congruent if—and only if—they can be changed into one another by an isometry, which is a mixture of rigid motions like translation, rotation, and reflection. This means that both objects can be exactly aligned with one another by moving and reflecting them, but not by resizing them.

In which ways may a fault be recognized in a landscape?
-fault scarp
-offset beds
-fault breccia
Faults are fractures that extend into the earth's crust and, in some instances, the mantle. Faulting has three principal types, each with distinct identifying characteristics and consequences.
Fault scarp, offset beds, and fault breccia are three ways in which a fault may be recognized in a landscape.What are fault scarps?A fault scarp is a linear vertical or near-vertical wall-like feature that develops along the earth's surface due to movement on the underlying fault. The surface trace of a fault is represented by a fault scarp, which is the outcrop or topographic expression of the fault plane in the surface.
The higher and steeper the scarp, the greater the relative motion on the fault.What are offset beds?An offset bed is a sedimentary layer or stratum that has been broken and displaced by faulting. The outcrop pattern of these layers is interrupted and does not match from one side of the fault to the other. In order to create a fault, one part of the ground must be shifted with respect to the other. This offset is noticeable on the exposed beds that appear on the fault surface.
The relative displacement of the rock layers that are divided by the fault is referred to as fault offset.What is fault breccia?Fault breccia is a type of rock that is created when rocks on either side of a fault are pulverized and mixed together as a result of the high stress associated with faulting. When a rock is fractured, it can be broken into tiny fragments known as breccia.
Fault breccia is a type of rock that is formed when the high stress associated with faulting crushes and grinds rock on either side of the fault until it becomes pulverized and is mixed together.

The swiss alps formed within the last 50 million years. The key mountain peak is Matterhorn peak. those rocks originally from ophiolites and sedimentary rocks of the Penninic nappes.
The Dent Blanche nappe's gneisses, which were formerly pieces of the African Plate before the Alpine orogeny, which are layered on top of the ophiolites and sedimentary rocks of the Penninic nappes make up the majority of the Matterhorn.
Due to numerous glaciers splitting from the peak, including the Matterhorn Glacier at the base of the north face, the mountain's current structure is the consequence of cirque erosion. It is sometimes referred to as the Mountain of Mountains (Berg der Berge in German) and has come to represent the Alps as a whole.
