Most beach sand is either composed mostly of eroded rock or of mechanically weathered marine organism skeletons, or a combination of both.
True. Rocks go through a process known as the rock cycle where they can be transformed from one type of rock to another through processes like erosion, deposition, heat, and pressure. This continuous cycle occurs over millions of years.
False. Rocks can change from one type to another through geological processes. For example, igneous rocks can become sedimentary rocks through weathering and erosion, while sedimentary rocks can transform into metamorphic rocks under heat and pressure. This cycle is part of the rock cycle, which illustrates the dynamic nature of Earth's materials.
This is false.
Generally, false. Intrusive rocks cool far more slowly than extrusive ones, so the crystals have time to grow larger.
That is false. The 3 main types of rocks are igneous, sedimentary, and metamorphic
False. While rocks deep in the ground may appear motionless, they are subject to movements caused by geological processes such as tectonic plate movement, erosion, and volcanic activity. Over long periods of time, these rocks can shift and change positions.
It can be either true or false. Some beaches are covered with sand. Others are covered in different types of materials such as pebbles.

false
False. More runoff can actually lead to more erosion, as the increased water flow can carry away soil particles and contribute to erosion.
