NOTES ON EARTH'S SURFACE, VOLCANIC ERUPTIONS, EARTHQUAKE MECL CODE: S6ESIVa-1 QUARTER 4, WEEK 1 Changes on Earth's surface caused by earthquakes: Earthquakes are caused by the movement of tectonic plates beneath the Earth's surface. When tectonic plates move, they can create seismic waves that can cause the ground to shake and buildings to collapse. Earthquakes can cause landslides, tsunamis, and the formation of new cracks or fissures in the ground. Earthquakes can also cause the ground to sink or rise, which can change the landscape of an area. Changes on Earth's surface caused by volcanic eruptions: Volcanic eruptions are caused by the movement of magma or molten rock beneath the Earth's surface. When magma rises to the surface, it can cause a volcanic eruption, which can release ash, gases, and molten lava. Volcanic eruptions can cause landslides, mudflows, and the destruction of buildings and homes. Volcanic eruptions can also create new landforms, such as mou...

A) Upwards B) Downwards C) Towards the surface D) Perpendicular to the surface   5) What is the relationship between friction and the motion of an object? A) Friction always causes an object to slow down ...
