Tenaga endogen dan eksogen mempengaruhi pembentukan.....
Correct Answer
D. Permukaan bumi
Explanation
The correct answer is "Permukaan bumi." The explanation for this answer is that both endogenous and exogenous forces play a role in shaping the Earth's surface. Endogenous forces, such as tectonic plate movements, can cause the formation of mountains, valleys, and other geological features. Exogenous forces, such as weathering and erosion, also contribute to the shaping of the Earth's surface by wearing away rocks and depositing sediment. Therefore, both endogenous and exogenous forces influence the formation of the Earth's surface.

Jenis gas yang keluar dari gunung berapi yang berupa uap air dinamakan....
Correct Answer
B. Fumarol
Explanation
A fumarol is a vent in the Earth's surface that emits steam and gases, including water vapor, sulfur dioxide, and hydrogen sulfide. It is commonly found near volcanoes and is formed when water comes into contact with hot rocks and magma underground. Therefore, the correct answer is fumarol, as it refers to the gas that is released from a volcano in the form of steam or water vapor.
3.
Pusat timbulnya gempa disebut....
Correct Answer
A. Hiposentrum
Explanation
The correct answer is "Hiposentrum." Hiposentrum refers to the point within the Earth's crust where the earthquake originates. It is the actual location where the seismic energy is released and the rocks break, causing the earthquake. The hiposentrum is usually located beneath the Earth's surface and can be measured in terms of depth.
4.
Bentuk endapan yang dihasilkan dari tenaga erosi organisme adalah.....
Correct Answer
B. Karang koral
Explanation
Karang koral adalah bentuk endapan yang dihasilkan dari tenaga erosi organisme. Karang koral terbentuk melalui proses akumulasi kalsium karbonat oleh organisme karang laut yang hidup di perairan. Organisme-organisme ini membangun struktur karang yang kuat dan kompleks, yang kemudian menjadi endapan karang koral. Erosi organisme terjadi ketika organisme karang ini mati dan meninggalkan struktur karang yang keras di dasar laut, yang kemudian menjadi endapan yang terus bertambah seiring waktu.

Kenampakan daratan yang letaknya rendah dari sekelilingnya akibat daratan di sekelilingnya patah disebut......
Correct Answer
D. Graben
Explanation
A graben is a type of landform that occurs when the surrounding land is broken and lowered, creating a depressed area. This can happen due to tectonic activity, such as faulting or rifting. In a graben, the central block of land sinks between two parallel faults, while the surrounding blocks remain at higher elevations. This creates a distinct trough-like feature with steep walls. Therefore, the correct answer is Graben.
6.
Pengaruh angin yang menyebabkan suatu tempat menjadi rendah disebut.....
Correct Answer
C. Degradasi
Explanation
The correct answer is Degradasi. Degradasi refers to the influence of wind that causes a place to become low or eroded. Deflasi refers to a decrease in the general price level of goods and services in an economy. Gradasi refers to the gradual change in a feature or characteristic over a distance. Korasi is not a recognized term in relation to the given context.
7.
Jenis batuan yang termasuk batuan malihan adalah......
Correct Answer
B. Gneiss
Explanation
Gneiss is classified as a metamorphic rock, which means it has undergone intense heat and pressure to transform from its original form. This makes it a type of rock that has changed or "shifted" from its original state, hence the term "batuan malihan" or "changed rock". Aluvium, Organik, and Leleran are not examples of metamorphic rocks, so they do not fit the criteria for being classified as "batuan malihan".
8.
Proses sktruktural meliputi......
Correct Answer
C. Lipatan
Explanation
The correct answer is "Lipatan." Lipatan refers to the process of folding in the Earth's crust due to tectonic forces. This process occurs when rock layers are subjected to compression, causing them to bend and fold. These folds can be seen in mountain ranges and are important in understanding the geologic history of an area.
9.
Gempa bumi yang hiposentrumnya sedalam 210 km,termasuk gempa.....
Correct Answer
B. Menengah
Explanation
The correct answer is "Menengah" because the earthquake's hypocenter is located at a depth of 210 km. This depth falls within the range of medium-depth earthquakes, which typically occur between 70 km to 300 km below the Earth's surface. Shallow earthquakes occur at depths of less than 70 km, while deep earthquakes occur at depths greater than 300 km. Therefore, "Menengah" is the most appropriate classification for this earthquake based on its hypocenter depth.
10.
Erosi percikan disebut juga...
Correct Answer
A. Splash erosion
Explanation
Splash erosion refers to the process where raindrops hit the soil surface with enough force to dislodge soil particles, causing them to splash and move away from their original position. This type of erosion is common in areas with bare soil or low vegetation cover, and it can lead to the formation of small pits and craters on the soil surface. Splash erosion is an important initial stage in the erosion process, as it can eventually lead to other forms of erosion such as sheet erosion or gully erosion.
