แบบทดสอบกลางภาค (๖๐ ข้อ)

The correct answer is "ถูกทุกข้อ" because all of the given options describe the phenomena that occur when an earthquake happens. The Earth's crust may rupture and cause tectonic plates to move (เปลือกโลกทรุดตัว), leading to a collision along fault lines (เปลือกโลกเกิดการกระแทกตามแนวระดับ), resulting in waves that propagate outward (เปลือกโลกเกิดกระทบกระแทกออกไปบริเวณรอบๆ ในรูปของคลื่น). Therefore, all of the options are correct.

The correct answer states that the surface of the Earth varies in characteristics according to its topography. This means that different regions of the Earth have different features and physical attributes based on their geographical makeup. This can include variations in elevation, terrain, climate, vegetation, and other factors that contribute to the overall diversity of the Earth's surface.

The correct answer is "ชั้นเปลือกโลก เนื้อโลก แก่นโลก". This answer correctly identifies the three main layers of the Earth's structure, which are the crust (เปลือกโลก), the mantle (เนื้อโลก), and the core (แก่นโลก). The crust is the outermost layer, followed by the mantle, and then the core.

The correct answer is "ถูกทุกข้อ" which means "all of the above". This answer suggests that all of the given phenomena (hot springs, hot water ponds, volcanic eruptions) demonstrate the presence of heat in the world.

The answer is "ถูกทุกข้อ" because all of the options mentioned are evidence that supports the belief of geologists and scientists that our world is constantly undergoing changes. The appearance of cracks in the Earth's crust, the occurrence of earthquakes, and the formation of mountains and volcanoes are all indications of the ongoing processes of transformation and change on our planet.

The correct answer is "ถูกทุกข้อ" which means "all of the above". The question is asking about the elements present in a layer that is both viscous and hot. The options given are silicon, iron, aluminum, and all of the above. Since all of these elements can exist in a layer that is both viscous and hot, the correct answer is "ถูกทุกข้อ" or "all of the above".

The correct answer is A and B. The movement of the Earth's crust due to the flow of magma in the mantle causes the continents of America, Europe, and Africa to separate over time. This movement is known as plate tectonics. Additionally, the intrusion of igneous rocks and the formation of volcanoes and landmasses in this region occur frequently. These processes contribute to the increasing separation between the continents.

The correct answer is "เปลือกโลกภาคพื้นทวีป และ เปลือกโลกใต้มหาสมุทร". This answer correctly identifies the two main divisions of the Earth's crust, which are the continental crust and the oceanic crust. The continental crust is the portion of the Earth's crust that makes up the continents, while the oceanic crust is the portion that forms the ocean basins. These two divisions have different compositions and characteristics, with the continental crust being thicker and less dense than the oceanic crust.

The correct answer is A and B because the ancient magnetic field site is used as evidence to prove both the paleomagnetic field reversal and the movement of tectonic plates.

The correct answer is "เคลื่อนที่แยกออกจากกัน" which means "moving apart from each other". This answer implies that the continents of America, Europe, and Africa are drifting away from each other. This phenomenon is known as continental drift, which is caused by the movement of tectonic plates on the Earth's surface. Over millions of years, the continents have moved and continue to move, resulting in the current positions and shapes of these continents.

The correct answer is "ซิลิคอนและแมกนีเซีย" (Silicon and magnesium). The Earth's crust is primarily composed of silicon and oxygen, forming a compound called silica. Silicon is the second most abundant element in the Earth's crust, while magnesium is the eighth most abundant. Both elements play important roles in the structure and composition of rocks and minerals found in the Earth's crust.

The correct answer is "ใต้เปลือกโลก" which translates to "under the Earth's crust". This answer is correct because the question is asking about the location of the epicenter or origin of an earthquake, which is typically beneath the Earth's surface. The Earth's crust is the outermost layer of the Earth, and earthquakes occur when there is a release of energy along fault lines within this layer. Therefore, the correct answer is "ใต้เปลือกโลก" or "under the Earth's crust".

The correct answer is "ธรณีภาค". This is because the term "ธรณีภาค" refers to the combination of the Earth's upper mantle and crust, which is the layer of the Earth's structure that includes both the Earth's crust and the uppermost part of the mantle.

The correct answer is "แผ่นเปลือกโลกขยายตัวและหดตัวเท่ากัน" (The Earth's crust expands and contracts equally). This is not a cause of earthquakes, but rather a description of the process of plate tectonics. Earthquakes are caused by the movement and collision of tectonic plates, not by the expansion and contraction of the Earth's crust.

The correct answer is "ชั้นแมนเทิล" (mantle). The question asks about the origin of volcanic ash, which is ejected from a volcano. This ash originates from the mantle, which is the layer of the Earth located between the crust and the core. The mantle is composed of solid rock that can melt and form magma, which is then ejected as volcanic ash during volcanic eruptions.

The correct answer is "เหล็กและนิกเกิล" because iron and nickel are the main elements that make up the Earth's core. The Earth's core is composed mainly of iron (about 85%) and nickel (about 10%). This composition is based on scientific studies and evidence, such as seismic waves and the Earth's magnetic field.

The correct answer is silicon and aluminum. The question asks about the elements that make up the continental crust. The continental crust is primarily composed of silicon and aluminum, along with other elements such as oxygen, iron, calcium, sodium, and potassium.

The correct answer is the flow of magma in the Earth's mantle. This is because the movement of magma in the Earth's mantle can cause the Earth's crust to move and result in the movement of tectonic plates, which in turn causes earthquakes, volcanic activity, and the shifting of continents.

The correct answer is "แก่นโลก" which translates to "core of the Earth" in English. The core of the Earth is the innermost layer and is composed of a solid inner core and a liquid outer core. It is the thickest layer of the Earth, with a radius of about 1,220 kilometers.

แก่นโลก is the correct answer because the Earth's core, which is located in the innermost layer of the Earth, has the highest temperature. The core is composed of a solid inner core and a liquid outer core, with temperatures reaching up to 5,430 degrees Celsius (9,806 degrees Fahrenheit). This makes the innermost layer of the Earth the hottest part of the planet.

The correct answer is the theory of plate tectonics. This theory explains the origin of continents, oceans, and the presence of fossils in rocks on Earth's surface. It states that the Earth's lithosphere is divided into several large plates that are constantly moving and interacting with each other. This movement is responsible for various geological processes such as earthquakes, volcanic activity, and the formation of mountains. The theory of plate tectonics provides a comprehensive explanation for the formation and movement of landmasses and the distribution of life on Earth.

Scientists study the internal structure of the Earth using seismic waves. When an earthquake occurs, it creates seismic waves that travel through the Earth. These waves can be detected and measured by seismographs. By analyzing the characteristics of these waves, scientists can determine the composition and structure of the Earth's interior. Therefore, the correct answer is "คลื่นความสั่นสะเทือนขณะเกิดแผ่นดินไหว" (seismic waves during an earthquake).

The correct answer is "จุดศูนย์กลางแผ่นดินไหว" (Center of the earthquake). This is because the question is asking for the term used to describe the origin or starting point of an earthquake. The term "จุดศูนย์กลางแผ่นดินไหว" specifically refers to the center or epicenter of an earthquake, where the seismic waves originate from.

The answer "ผลกระทบจากแผ่นดินไหวของบริเวณใกล้เคียง" (Impact from nearby earthquakes) is the correct answer because it is stated in the question that the question is asking about the biggest change in the Earth's crust that supports Thailand. The impact from nearby earthquakes can cause significant changes in the Earth's crust, including the formation of mountains, valleys, and other geological features. This makes it the most plausible answer compared to the other options given.

The correct answer is that the composition of the rock Sial is mainly composed of silicon and aluminum.

The correct answer is "แผ่นธรณีภาคพื้นทวีปกับแผ่นธรณีภาคพื้นทวีป". This answer suggests that the Alps mountain range in Europe was formed by the collision of two continental plates, specifically the Eurasian plate and the African plate. This collision caused the crust to buckle and fold, resulting in the formation of the Alps.

The correct answer is "แมนเทิล" because the question is asking for the layer of the Earth's crust that has the highest percentage of mass. The mantle is the layer below the Earth's crust and it is much denser and thicker, making up about 84% of the Earth's total volume and about 67% of its mass. Therefore, the mantle has the highest percentage of mass compared to the other layers mentioned in the options.

The answer states that the layer below the Earth's crust is called the mantle. This is correct as the mantle is the layer between the crust and the core of the Earth. It is a solid layer that is mostly made up of silicate rocks and is responsible for the movement of tectonic plates.

The answer is incorrect because the lower part of the Earth's crust is composed of basalt, not basalt. Basalt is a type of volcanic rock that is formed from the solidification of lava, while basalt is a type of sedimentary rock that is formed from the accumulation and compaction of sediment. Therefore, the correct statement should be "The lower part of the Earth's crust is composed of basalt."
