[Q4] CHANGES ON THE EARTH'S SURFACE DUE TO EARTHQUAKES AND VULCANIC ERUPTIONS (S6ES-IVa-1)
Changes on Earth's Surface Due to Earthquakes and Volcanic Eruptions ( S6ES-IVa-1) PJ MIANA 1. Earthquakes: - Earthquakes are the result of the sudden release of energy in the Earth's crust, leading to the shaking or trembling of the ground. - Surface changes caused by earthquakes include: - Ground Shaking: Earthquakes can cause the ground to shake violently, resulting in buildings, roads, and other structures to collapse or be damaged. - Faulting: Earthquakes can create or widen fractures in the Earth's crust known as faults. These can be seen as cracks on the surface of the Earth. - Landslides: The shaking from earthquakes can trigger landslides, where large amounts of soil and rock move downhill rapidly. - Surface Ruptures: In some cases, earthquakes can cause the ground to rupture or split open along fault lines, resulting in visible changes in the landscape. 2. Volcanic Eruptions: - Volcanic eruptions occur when magma, gase
