The answer is B. folding, uplift, and erosion. certain mountains are created from the folding of the upper layers of earth's crust. valleys on the other hand are made from the erosion of land or soil. tectonic uplift of the earths crust is also responsible for creating mountains.
The lithosphere, which is the rigid outermost shell of a planet (the crust and upper mantle), is broken up into tectonic plates. The Earth's lithosphere is composed of seven or eight major plates (depending on how they are defined) and many minor plates. Where the plates meet, their relative motion determines the type of boundary: convergent, divergent, or transform. Earthquakes, volcanic activity, mountain-building, and oceanic trench formation occur along these plate boundaries. The relative movement of the plates typically ranges from zero to 100 mm annually.[2]
Tectonic plates are composed of oceanic lithosphere and thicker continental lithosphere, each topped by its own kind of crust. Along convergent boundaries, subduction carries plates into the mantle; the material lost is roughly balanced by the formation of new (oceanic) crust along divergent margins by seafloor spreading. In this way, the total surface of the lithosphere remains the same. This prediction of plate tectonics is also referred to as the conveyor belt principle. Earlier theories, since disproven, proposed gradual shrinking (contraction) or gradual expansion of the globe.[3]
Tectonic plates are able to move because the Earth's lithosphere has greater strength than the underlying asthenosphere. Lateral density variations in the mantle result in convection. Plate movement is thought to be driven by a combination of the motion of the seafloor away from the spreading ridge (due to variations in topography and density of the crust, which result in differences in gravitational forces) and drag, with downward suction, at the subduction zones. Another explanation lies in the different forces generated by tidal forces of the Sun and Moon. The relative importance of each of these factors and their relationship to each other is unclear, and still the subject of much debate.

<h3>What is Social workers?</h3>
Social workers refer to people who study social work as a disciple or profession which entails the study of people, individuals, families, groups, communities, and society as a whole in order to meet their basic needs and enhance social functioning, self-determination, collective responsibility, good health and their general wellbeing.
Therefore, Strengths Perspective is not a practice use by social workers to gain cultural competence in their practices with different groups.

Answer:
Los mares cerrados, como el Mar Mediterráneo, presentan mayores niveles de contaminación porque son entera o mayoritariamente formados por cuencas endorreicas, las cuales no tienen salida directa hacia el océano. De esta manera, las corrientes marítimas no desagotan sus residuos en el océano, sino que continúan retroalimentándose de manera cícilica, con lo que el conjunto de desechos que viaja en dichas corrientes se queda constantemente dentro de la misma cuenca.
Answer: Somalia is located at letter <u>D</u>, and Sudan is located at letter <u>B</u>.
Explanation:
In the first image attached is shown the map of Africa with the letters, and in the second image the map with the name of the countries. As we can see, letter D corresponds to Somalia and letter B to Sudan.
In this sense, Somalia is located on the line of the Earth's equator and is the easternmost country in Africa. It is mainly composed of plains, plateaus and highlands. In addition, it maintains a warm climate throughout the year with inclement summers, except in the higher altitude territories of the north of the country.
On the other hand, Sudan is located in North Africa, on the shores of the Red Sea, between Egypt and Eritrea. It is partly crossed by the Nile and its tributaries. To the south its climate is tropical, while in the north it is desert, with daily temperatures exceeding 42 ° C.
