Soal IPA Kelas 4 Sd Bab 9 Perubahan Kenampakan Bumi Dan Benda Langit - Www.Bimbelbrilian.Com

Kebakaran hutan akan menyebabkan terjadinya polusi di udara. Ketika hutan terbakar, banyaknya asap dan partikel-partikel yang terlepas ke udara dapat mencemari udara dan menghasilkan polusi. Polusi udara dapat memiliki efek negatif pada kualitas udara, kesehatan manusia, dan ekosistem. Partikel-partikel yang terhirup dapat menyebabkan masalah pernapasan dan penyakit, sementara polutan yang terlepas ke atmosfer dapat menyebabkan efek rumah kaca dan perubahan iklim. Oleh karena itu, kebakaran hutan dapat menyebabkan terjadinya polusi udara yang merugikan bagi lingkungan dan manusia.

The sun appears very small because it is located far away from the Earth.

During the daytime, the Earth appears bright because it is being illuminated by the sun's rays. The sun is the primary source of light and heat for the Earth, and its rays reach the planet during the day, causing it to be well-lit. This is why the correct answer is "Terkena sinar matahari" or "Being exposed to sunlight."

Daerah pegunungan yang memiliki sedikit pepohonan bisa mudah terjadi tanah longsor. Kurangnya pepohonan menyebabkan tanah menjadi tidak stabil dan rentan terhadap erosi. Ketika terjadi hujan deras, air akan meresap ke dalam tanah yang tidak stabil dan menyebabkan longsor. Hal ini dapat menyebabkan kerusakan pada lingkungan dan bahkan membahayakan kehidupan manusia.

Forests are often referred to as the "lungs of the world" because they play a crucial role in producing oxygen and absorbing carbon dioxide. They help to regulate the Earth's climate by reducing the amount of greenhouse gases in the atmosphere. Forests also provide habitat for a wide variety of plant and animal species, contributing to biodiversity. Additionally, they help to prevent soil erosion, regulate water cycles, and provide resources such as timber, food, and medicinal plants. Therefore, forests are essential for human survival and well-being.

The correct answer is "Fase bulan". This is because "fase bulan" refers to the different shapes or phases of the moon as it orbits the Earth. The moon goes through a cycle of phases, including new moon, crescent moon, half moon, gibbous moon, and full moon. Therefore, "fase bulan" is the appropriate term to describe the changing shape of the moon.

Badai di laut dapat menyebabkan ombak besar. Badai adalah kondisi cuaca yang ditandai dengan angin kencang dan gelombang laut yang tinggi. Angin kencang yang terjadi selama badai dapat mendorong air laut dan membentuk ombak besar. Ombak besar ini dapat menjadi ancaman bagi kapal-kapal di laut dan juga dapat menyebabkan kerusakan pada pantai serta pesisir. Oleh karena itu, badai di laut dapat menyebabkan ombak besar.

Burning trash indiscriminately in the forest can cause wildfires.

Pohon bakau adalah pilihan yang tepat untuk ditanam di pinggir pantai guna mengurangi pengikisan. Hal ini karena akar pohon bakau memiliki kemampuan untuk menahan tanah dan pasir, sehingga dapat membantu menjaga kestabilan pantai. Selain itu, pohon bakau juga dapat menyerap air laut yang berlebihan dan membantu mengurangi dampak erosi akibat gelombang air laut.

Angin kencang yang menyertai cuaca buruk dinamakan badai. Badai adalah fenomena cuaca yang ditandai oleh angin kencang, hujan deras, petir, dan kadang-kadang disertai oleh hujan es atau tornado. Badai seringkali dapat menyebabkan kerusakan yang signifikan pada bangunan dan infrastruktur serta berpotensi membahayakan keselamatan manusia.

In the morning, our shadow will be on the opposite side of the sun. Since the sun rises in the east, our shadow will be towards the west. Therefore, the correct answer is "Barat" which means west in Indonesian.

Bintang adalah benda langit yang memancarkan cahayanya sendiri. Bintang terbentuk dari gas dan debu yang tertarik oleh gravitasi dan mengalami reaksi nuklir di intinya, menghasilkan energi dan cahaya. Cahaya yang dipancarkan oleh bintang ini dapat dilihat dari Bumi dan memberikan penerangan di malam hari. Benda langit lain seperti Bulan, Bumi, dan Planet tidak memancarkan cahayanya sendiri, melainkan hanya memantulkan cahaya dari Matahari.

The changing positions of the sun, moon, and earth cause the shape of the moon to appear different over time. This is why the moon appears to go through different phases and why its shape appears to change.

When the surface of the ground is not protected by plants and trees, it becomes more vulnerable to erosion by water. Without the roots of plants holding the soil in place, water can easily wash away the top layer of soil, causing it to be easily eroded.

The moon shines at night because it reflects light from the sun.

Reboisasi is the process of replanting trees in an area where they have been cut down or destroyed. It is a positive action that helps restore the natural environment and prevent erosion. Therefore, it does not cause changes in the appearance of the earth like storms, erosion, or fires do.

Pasang naik is the correct answer because it refers to the condition where the sea level rises, causing the sea water to appear to increase and the coastline to shift upwards. "Pasang surut" refers to the tidal phenomenon where the sea level alternately rises and falls. "Naik surut" is not a commonly used term in this context. "Angin darat" refers to land wind and is unrelated to the given question.

Bulan bukan merupakan bintang karena tidak memiliki cahaya sendiri. Bintang memiliki cahaya sendiri karena mereka menghasilkan energi melalui reaksi nuklir di inti mereka. Bulan, di sisi lain, tidak menghasilkan cahaya sendiri. Cahaya bulan yang kita lihat sebenarnya adalah pantulan cahaya matahari yang dipantulkan oleh permukaannya.

A tsunami is a very large ocean wave caused by underwater earthquakes, volcanic eruptions, or landslides. Unlike regular ocean waves, a tsunami can travel across entire ocean basins and cause significant destruction when it reaches coastal areas. Therefore, it is the correct answer for the question about a very large ocean wave.

The given question asks for the term used to describe a group of stars arranged in a specific pattern in the sky. The correct answer is "Rasi bintang" which translates to "constellation" in English. A constellation is a group of stars that form a recognizable pattern or shape as seen from Earth. These patterns have been named and identified by ancient civilizations to help navigate the night sky and tell stories.

Tumbuhan dengan akar yang kuat dapat menahan tanah dari air karena akar tersebut merambat dan menjalin erat dengan partikel-partikel tanah. Hal ini membuat tanah menjadi lebih stabil dan tidak mudah terkena erosi akibat air yang mengalir. Akar tumbuhan juga membantu dalam menjaga kelembapan tanah dengan menyerap dan menyimpan air, sehingga tanah tetap subur dan tidak mengalami kekeringan.

The correct answer is "Gaya tarik bulan" (The gravitational pull of the moon). This is because the moon's gravitational force affects the oceans, causing the tides to rise and fall. The moon's gravity pulls on the water, creating a bulge on the side of the Earth facing the moon and a corresponding bulge on the opposite side. As the Earth rotates, different parts of the planet experience high and low tides. The gravitational pull of the sun also contributes to the tides, but it is less significant compared to the moon's gravitational force.

Erosi refers to the process of soil erosion caused by the movement of water. It occurs when water carries away the top layer of soil, leading to the loss of fertile soil and potential damage to the environment. This process is often caused by factors such as heavy rainfall, improper land management, and deforestation. Reboisasi, on the other hand, refers to the process of replanting trees to restore forests, while abrasion refers to the wearing away of rocks and sediments by friction. Organisasi is unrelated to the erosion process.

Angin yang bergerak dari laut ke darat disebut angin darat.

A perpustakaan (library) is a building that houses various resources such as books, documents, and other materials for research and learning purposes. It does not have any equipment or tools specifically designed for demonstrating the positions and movements of celestial objects. Therefore, the correct answer is not perpustakaan.
