The correct answer is "รอบๆ มหาสมุทรแปซิฟิก" because the Pacific Ring of Fire is known for its high volcanic activity. This region is located along the edges of the Pacific Ocean and is characterized by a large number of active volcanoes and frequent earthquakes. The volcanic eruptions in this area are the most intense and frequent compared to other regions, making it the location with the highest volcanic activity.

The study of data on changes in the Earth's crust is conducted to find the causes of these changes, to identify ways to mitigate the impacts resulting from these changes, and to develop strategies for preventing the potential consequences of these changes.

The correct answer is 2 3 5 1 4. This sequence of events explains the process of seafloor spreading and the formation of mid-ocean ridges. It starts with the uplift of the oceanic crust due to the intrusion of magma, followed by the decrease in temperature and pressure causing the formation of a rift or a trench. Then, the magma intrudes and pushes the lower oceanic crust apart, causing the separation of the two sides of the rift. Finally, the formation of a central mountain range occurs due to the continued intrusion of magma.

The correct answer is "กลอสซอพเทอริส" because it is the only option that is found in all the mentioned regions - South America, Africa, India, Antarctica, and Australia.

Tsunamis are geological events that occur due to internal factors within the Earth's crust, such as earthquakes, volcanic eruptions, or underwater landslides. These events can cause a sudden displacement of water, resulting in powerful waves that can travel across the ocean and cause significant damage when they reach the coastline. Unlike the other options, which are not directly related to geological processes, tsunamis are a clear example of a natural phenomenon caused by internal factors within the Earth.

The correct answer is "ส่วนบนของเนื้อโลกรวมกับเปลือกโลก" which means "the upper part of the mantle combined with the crust." This answer correctly identifies the lithosphere as the uppermost layer of the Earth's solid material, consisting of the crust and the uppermost part of the mantle. It distinguishes the lithosphere from the asthenosphere, which is the partially molten, ductile layer beneath it.

The correct answer is "แผ่นอเมริกาใต้ - แผ่นแอฟริกา". This is because the question is asking which pair of continents is currently moving apart from each other. The South American Plate and the African Plate are indeed moving away from each other, which is supported by geological evidence of divergent boundaries and the formation of the Mid-Atlantic Ridge.

เนื้อสารภายในโลกมีความหนาแน่นไม่สม่ำเสมอเพราะแนวทางการเคลื่อนที่ของคลื่นแผ่นดินไหวเป็นเส้นโค้ง คลื่นแผ่นดินไหวมีลักษณะการกระจายตัวที่เป็นเส้นโค้ง เมื่อคลื่นแผ่นดินไหวเกิดขึ้น คลื่นจะกระจายตัวไปทั่วทั้งโลก แต่ความหนาแน่นของคลื่นจะไม่เท่ากันทุกจุด จุดที่อยู่ใกล้กับแหล่งเกิดคลื่นจะมีความหนาแน่นมากกว่าจุดที่อยู่ไกลออกไปจากแหล่งเกิดคลื่น ซึ่งสรุปได้ว่า เนื้อสารภายในโลกมีความหนาแน่นไม่สม่ำเสมอ

The evidence that supports the movement of the tectonic plates is the discovery of deep trenches along the length of the mid-ocean ridge. These trenches indicate that one tectonic plate is subducting or moving beneath another plate, which is a clear indication of plate movement. This evidence suggests that the plates are not stationary but are actively moving and interacting with each other.

The correct answer is that the tectonic plates move apart. This movement is known as divergent plate boundaries, where the plates separate from each other. As the plates move apart, magma rises from the mantle and fills the gap, creating new crust. This process is responsible for the formation of mid-ocean ridges and the creation of new oceanic crust.

The correct answer states that 150 million years ago, Laurasia and Gondwana were formed. Laurasia and Gondwana were two supercontinents that existed during the Mesozoic Era. Laurasia was located in the northern hemisphere and consisted of present-day North America, Europe, and Asia (excluding India). Gondwana was located in the southern hemisphere and consisted of present-day South America, Africa, Australia, Antarctica, and the Indian subcontinent. This answer accurately describes the formation of these two supercontinents during that time period.

The correct answer is that the subducting tectonic plate in the southern ocean moves towards and collides with the continental tectonic plate. This collision creates deep ocean trenches and volcanic mountain ranges on the continental side.

The widening of the Pacific Ocean by 8 centimeters per year is the best explanation for the given question. This is because the other options, such as the extinction of dinosaurs, drought in Asia, and landslides in India, do not provide a clear explanation for the event described. The widening of the Pacific Ocean is a significant geological phenomenon that can be measured and observed, making it the most plausible answer.

The correct answer is that the southern tectonic plate moves and collides with the southern tectonic plate. This movement and collision between the two plates result in the formation of deep ocean trenches and volcanic mountain ranges in the middle of the ocean.

The correct answer is "ขอบแผ่นธรณีภาคเคลื่อนที่ผ่านกัน" which means "The tectonic plates move past each other." This explanation suggests that the San Andreas Fault is formed by the movement of tectonic plates sliding horizontally past each other. This type of movement is known as a transform boundary, where the plates move in opposite directions. The sliding motion can cause earthquakes as the plates become locked and then suddenly release the built-up stress.

The correct answer is "ขอบตะวันออกของอเมริกาใต้ สามารถต่อกับขอบตะวันตกของแอฟริกาใต้พอดี". This is supported by the fact that the eastern coast of South America lines up perfectly with the western coast of Africa, indicating that they were once connected and have since drifted apart. This alignment is evidence of continental drift and supports the theory proposed by Dr. Wegener.

The correct answer is "ภาคใต้" because the term "รอยเลื่อนคลองมะรุ่ย" refers to a significant landslide that occurred in the southern region of Thailand.

The question asks for the country that does not usually experience earthquakes. The correct answer is "อินเดีย" (India). This is because India is located in a region where earthquakes are less frequent compared to countries like Japan, Colombia, and China.

เกิดหุบเขาทรุด (Rift Valley) จากสาเหตุที่เกี่ยวข้องกับขอบแผ่นธรณีภาคแยกออกจากกัน แม้ว่ามีน้ำทะเลไหลเข้ามาสะสมที่เปลือกโลกและแมกมาในชั้นฐานธรณีภาคดันตัวขึ้นถึงชั้นธรณีภาค แต่เหตุการณ์หุบเขาทรุดเกิดจากการแยกแยะของขอบแผ่นธรณีภาค ซึ่งทำให้เกิดร่องลึกขึ้นในพื้นผิวโลก ดังนั้น คำตอบที่ถูกต้องคือ "เกิดจากขอบแผ่นธรณีภาคแยกออกจากกัน"

The correct answer is Continental Drift Theory. Alfred Wegener proposed the theory of continental drift, which states that the continents were once joined together in a supercontinent called Pangaea and have since drifted apart. This theory explains the similarities in rock formations, fossils, and mountain ranges found on different continents. It also accounts for the matching coastlines of South America and Africa. However, it was not widely accepted until the development of plate tectonics in the 1960s.

The term "Ring of Fire" refers to a major area in the basin of the Pacific Ocean where a large number of earthquakes and volcanic eruptions occur. This area is associated with a nearly continuous series of oceanic trenches, volcanic arcs, volcanic belts, and plate movements. The collision between the oceanic plate and continental plate in the Ring of Fire is responsible for the occurrence of earthquakes and volcanic eruptions. Therefore, the correct answer is "แผ่นใต้มหาสมุทรชนกับแผ่นใต้มหาสมุทร" which means the collision between the oceanic plate and oceanic plate.

The correct answer is that the tectonic plates at the Red Sea and the Gulf of California move apart from each other. This is known as a divergent boundary, where two plates move away from each other, creating a gap between them. This movement can result in the formation of new crust as magma rises to fill the gap, leading to the creation of new oceanic crust in these regions.

The statement that the central oceanic ridge is curved is incorrect. The central oceanic ridge is actually a long, straight underwater mountain range that runs through the middle of the ocean basins. It is formed by the divergence of tectonic plates and the upwelling of magma from the mantle. The ridge is not curved, but rather has a linear shape.
