Correct Answer
C. Konsep keterkaitan keruangan
Explanation
The correct answer is "konsep keterkaitan keruangan" because the question states that houses in Sumatra are mostly built on stilts, while this type of house is not found in Java. This phenomenon can be explained by the concept of spatial connectivity, which refers to the interconnectedness and relationships between different areas or regions. In this case, the difference in house architecture can be attributed to the geographical and cultural differences between Sumatra and Java, leading to distinct spatial patterns and practices in each region.

Correct Answer
A. Pendekatan keruangan dan ekologi
Explanation
The correct answer is "pendekatan keruangan dan ekologi" because it suggests that the most appropriate approach to understanding the distribution, interrelation, and problem-solving of the flood that occurred in Jakarta in 2007 is through spatial and ecological analysis. This approach would involve examining the spatial patterns of the flood and considering the ecological factors that contributed to its occurrence, such as land use, drainage systems, and environmental impacts. By using this approach, researchers can gain a comprehensive understanding of the flood and develop effective strategies for mitigating its impacts in the future.

Correct Answer
B. Erosi angin
Explanation
The given image shows the landforms formed due to wind erosion. Wind erosion occurs when the force of wind carries away loose soil and rocks, shaping the land over time. This can result in features such as sand dunes, desert pavement, and rock pedestals.

Pada asaat terjadi gempa gelombang primer tercatat pukul 12,36’,55’’, jika jarak seismograf dengan episentrum 2200 km, maka gelombang sekunder tercatat oleh seismograf pukul ... .
Correct Answer
D. 12, 40’ 07’’
Explanation
The time difference between the arrival of primary waves and secondary waves at the seismograph station is used to determine the distance from the epicenter of an earthquake. In this case, the primary waves arrived at 12:36'55'' and the seismograph is located 2200 km away from the epicenter. The secondary waves would take a longer time to arrive, so the seismograph would record them at a later time. Among the given options, 12:40'07'' is the closest time to the expected arrival of the secondary waves, making it the correct answer.

Bentuk muka bumi hasil erosi dan sedimentasi sehingga muka bumi hampir rata dinamakan ... .
Correct Answer
E. Peneplain
Explanation
A peneplain is a landform that has been eroded and then flattened by the process of erosion and sedimentation. It is characterized by a nearly flat surface. In this context, the question is asking for the name of the landform that is the result of erosion and sedimentation, and has a nearly flat surface. Therefore, the correct answer is peneplain.

Hancurnya batuan mejadi kepingan-kepingan kecil yang diakibatkan perubahahn temperatur dalam waktu tertentu, merupakan hasil dari proses ... .
Correct Answer
A. Pelapukan
Explanation
The given correct answer for this question is "pelapukan". Pelapukan refers to the process of breaking down rocks into smaller pieces due to changes in temperature over time. This process does not involve the deposition of sediments (sedimentasi), the breaking of rocks along faults (patahan), the folding of rocks (lipatan), or the erosion of rocks (erosi). Therefore, pelapukan is the most appropriate answer.
10.
Spit dan tanah pasir terbentuk akibat dari proses sedimentasi oleh tenaga ... .
Correct Answer
E. Air laut
Explanation
The correct answer is "air laut" because sea water is one of the forces that causes sedimentation. As waves crash onto the shore, they carry sediments and deposit them on the land, forming sand and mud. This process is known as marine sedimentation.
