Pulau Jawa merupakan daerah penghasil padi utama di Indonesia karena tanah di pulau Jawa subur dan air tersedia cukup banyak serta wilayahnya merupakan datarann rendah sehingga cocok untuk tanaman padi. Konsep dasar geografi untuk memahami fenomena tersebut adalah ….
Correct Answer
B. Konsep keterkaitan keruangan
Explanation
The correct answer is "konsep keterkaitan keruangan" because it refers to the concept of spatial interdependence, which means that the characteristics and phenomena of a certain area are interconnected and influenced by its surrounding areas. In this case, the fertility of the land and the availability of water in Pulau Jawa contribute to its status as the main rice-producing region in Indonesia. The concept of keterkaitan keruangan explains how the geographical features and resources in an area are interconnected and affect its economic activities and agricultural productivity.

Di kota besar seperti Jakarta, banyak terdapat pemukiman kumuh, gelandangan, dan pengemis memanfaatkan daerah aliran sungai untuk pemukiman sehingga pada musim hujan terjadi banjir. Untuk mengatasi terjadinya banjir dibangun Banjir Kanal Timur dan Banjir Kanal Barat. Pendekatan yang digunakan untuk mengkaji kasus itu adalah ….
Correct Answer
C. Pendekatan keruangan
Explanation
The correct answer is "pendekatan keruangan." This is because the passage mentions the existence of slums, homeless people, and beggars utilizing river areas for settlements, leading to flooding during the rainy season. To address this issue, the Banjir Kanal Timur and Banjir Kanal Barat were constructed. The term "keruangan" refers to the spatial aspect of the problem, focusing on the physical and geographical factors that contribute to the occurrence of floods in certain areas. Therefore, the approach used to study this case is the spatial approach.

Betonisasi dan pengaspalan jalan di kota-kota besar menyebabkan luas lahan untuk resapan air berkurang. Hal itu menyebabkan debit air sungai dan air tanah berkurang pada musim kemarau. Prinsip geografi yang berkaitan dengan fenomena tersebut adalah ….
Correct Answer
C. Prinsip interelasi
Explanation
The correct answer is "prinsip interelasi" because it refers to the principle of interrelation or interconnectedness between different elements or phenomena in geography. In this case, the phenomenon of reduced water flow in rivers and groundwater during the dry season is directly related to the decrease in land area available for water infiltration due to the concrete and asphalt paving of roads in urban areas. This shows how human activities can impact the natural water cycle and highlights the interconnectedness between urban development and hydrological processes.

Fenomena geosfer :1)padang gurun2)pola aliran sungai3)pola pemukiman penduduk4)daerah transmigrasi5)kualitas penduduk Aspek sosial dari fenomena di atas terdapat pada angka ….
Correct Answer
E. 3), 4), dan 5)
Explanation
The correct answer is 3), 4), dan 5). The social aspects of the geosphere phenomenon can be found in the patterns of human settlement (pola pemukiman penduduk), the areas of transmigration (daerah transmigrasi), and the quality of the population (kualitas penduduk). These aspects involve how people interact with and adapt to the physical environment, such as establishing communities in certain areas, relocating to new regions, and the overall characteristics and well-being of the population in relation to their surroundings.

Pernyataan :1) terbentuknya pegunungan lipatan muda Himalaya- gerakan saling menjauh antara lempeng Afrika dengan Amerika bagian selatan.
- pembentukan tanggul dasar samudera (med ocean ridge)
- terbentuknya Pegunungan Alpen.
- terbentuknya Pegunungan Rocky dan Pegunungan Andes.
Pernyataan di atas yang merupakan peristiwa konvergen adalah ….
Correct Answer
C. 1), 4) dan 5)
Explanation
The correct answer is 1), 4) and 5). Statement 1) refers to the formation of the young folded mountains, which is a result of the convergence of tectonic plates. Statement 4) mentions the formation of the Rocky Mountains, which is also a result of plate convergence. Statement 5) talks about the formation of the Andes Mountains, which is another example of convergent plate boundaries. Therefore, these statements represent events of plate convergence.

Wilayah yang terbentuk dari adanya tumbukan lempeng seperti gambar adalah ....
Correct Answer
A. Terbentuknya gunung api
Explanation
The correct answer is "terbentuknya gunung api". The given question is asking for the formation of a certain area resulting from plate collisions shown in the picture. The formation of mountains is a common occurrence in plate tectonics when two plates collide. This collision causes intense pressure and forces one plate to be pushed beneath the other, resulting in the formation of a volcanic mountain range known as a "gunung api" in Indonesian.

Pernyataan :1) tata surya pada awalnya hanya matahari saja tanpa mempunyai anggota.2) Planet-planet dan anggota lainnya terbentuk karena adanya bagian dari matahari yang tertarik dan terlepas oleh pengaruh gravitasi bintang yang melintas ke dekat matahari.3) Bagian yang terlepas itu berbentuk seperti cerutu panjang (bagian tengah besar dan kedua ujungnya mengecil) yang terus berputar mengelilingi matahari,- sehingga lama kelamaan mendingin membentuk bulatan-bulatan yang disebut planet.
Berdasarkan pernyataan di atas, teori pembentukan tata surya yang dimaksud adalah ...
Correct Answer
C. Teori Pasang Surut (Jeans dan Jeffries)
Explanation
The given statement describes the formation of the solar system through the process of gravitational attraction and the separation of parts from the sun. These parts, resembling a long cigar shape, eventually cooled down and formed the planets. This description aligns with the theory of tidal forces proposed by Jeans and Jeffries, which suggests that the gravitational forces between the sun and passing stars caused the formation of the solar system.

Pernyataan tentang Jagatraya :1) alam semesta tidak ada awal dan akhirnya2) berawal dari masa besar dan berat jenis besar juga3) ledakan besar terjadi dari inti4) didasarkan pada observasi dari Edwain Hubble dan didukung Stephen Hawking- alam yang lama diganti dengan yang baru silih berganti
Teori Jagatraya berdasarkan pernyataan di atas yang termasuk Teori Bigbang adalah ...
Correct Answer
C. 2), 3), dan 4)
Explanation
The statement about Jagatraya states that the universe has no beginning or end, it originated from a big mass and high density, and a big explosion occurred from the core. These statements align with the theory of Big Bang, which suggests that the universe started from a singularity and expanded. The observations made by Edwin Hubble and the support from Stephen Hawking further strengthen the theory. Therefore, options 2), 3), and 4) are correct as they include all the statements related to the Big Bang theory.

Ciri-ciri planet :- merupakan planet terdekat ke Matahari:
- rata-rata jaraknya yaitu sekitar 58.000.000 kilometer;
- dilihat dari ukurannya, merupakan planet terkecil;
- periode rotasi Merkurius menghabiskan waktu 59 hari;
- satu kali revolusi mengelilingi Matahari adalah 88 hari;
- Atmosfer planet ini sangat tipis, tersusun dari gas Helium.
Planet yang sesuai dengan ciri-ciri tersebut adalah ....
Correct Answer
B. Merkurius
Explanation
Merkurius is the correct answer because it is the planet closest to the Sun with an average distance of about 58,000,000 kilometers. It is also the smallest planet in terms of size. The rotation period of Merkurius is 59 days, and it takes 88 days to revolve around the Sun. Additionally, Merkurius has a very thin atmosphere composed of helium gas.

Fenomena Geofer :1) slenk2) graben3) dendritik4) antiklinal5) geyser Termasuk akibat lempeng tektonik yang terus bergerak, baik secara horizontal maupun vertikal karena pengaruh arus konveksi dari lapisan di bawahnya (astenosfer) dari pernyataan di atas adalah …
Correct Answer
B. 1), 2), dan 4)
Explanation
The correct answer is 1), 2), and 4). This is because slenk, graben, and antiklinal are all geological phenomena that occur as a result of the continuous movement of tectonic plates. Slenk refers to a downward or sideways displacement of rock layers along a fault line, graben is a depressed block of land bordered by parallel faults, and antiklinal is an upward fold in rock layers. These phenomena are caused by the horizontal and vertical movement of tectonic plates influenced by convection currents from the asthenosphere.
