Rock Cycle Notes Quiz - Mahoney

Explanation
Metamorphic rock is formed through the process of metamorphism, which involves the transformation of existing rock types due to high temperatures and intense pressure. Heat is necessary to cause the minerals in the rock to recrystallize and rearrange their structure, while pressure is required to compact and deform the rock. The combination of heat and pressure alters the mineralogy, texture, and overall composition of the rock, resulting in the formation of metamorphic rock.

Explanation
Igneous rock is formed through the cooling of magma. Magma is molten rock that is found beneath the Earth's surface. When magma cools and solidifies, it forms igneous rock. This process can occur either on the Earth's surface, resulting in extrusive igneous rocks, or beneath the surface, resulting in intrusive igneous rocks. The cooling of magma is a key factor in the formation of igneous rocks and is responsible for their characteristic crystalline structure and texture.

Explanation
The rock cycle is a series of processes that transform one type of rock into another over time. These processes include weathering, erosion, deposition, compaction, and cementation. Weathering breaks down rocks into smaller pieces, which are then transported and deposited by wind, water, or ice. Over time, these sediments are compacted and cemented together to form sedimentary rocks. Through heat and pressure, sedimentary rocks can be transformed into metamorphic rocks. And through melting and cooling, igneous rocks can form. This continuous cycle of processes is known as the rock cycle.

Explanation
Erosion refers to the process of moving small pieces of rock from one place to another through the action of wind, water, or glaciers. This process involves the gradual wearing away and transportation of rocks, sediments, and soil particles. Weathering, on the other hand, refers to the breakdown of rocks into smaller pieces due to natural processes such as exposure to weather conditions. Cementation is the process of binding or cementing sediments together to form rock. Rock flow is not a term commonly used to describe the movement of small pieces of rock.

Explanation
The statement is true because the three major types of rock, which are igneous, sedimentary, and metamorphic, can undergo a process called the rock cycle. This cycle involves the transformation of one type of rock into another through various geological processes such as weathering, erosion, heat, and pressure. For example, igneous rock can be weathered and eroded to form sediment, which can then be compacted and cemented to become sedimentary rock. This sedimentary rock can then be subjected to heat and pressure, transforming it into metamorphic rock. Therefore, any of the three major types of rock can change into one of the other types.
