| Metamorphic rocks live, die and are reborn as part of the never-ending rock cycle. |
|
| A part of the plate tectonics revolution, known as the Wilson cycle, has had profound effects on the modern interpretation of the rock cycle. |
|
| Igneous, sedimentary and metamorphic are the 3 major group of rocks that undergo a rock cycle. |
|
| Weathering and erosion are part of the rock cycle process that help shape the Earth's surface. |
|
| There is no beginning or end to a rock cycle, with change occuring very slowly during that process |
|
| They should also see that the relationship of the formation of rocks can be depicted in a rock cycle. |
|
| Students may simulate the creation of several rock types in the rock cycle, using shavings from coloured wax crayons. |
|
| The rock cycle illustrated in Figure 1 reflects the basic relationships among igneous, metamorphic, and sedimentary rocks. |
|
| They can be likened to other broad natural cycles, such as the water cycle and the rock cycle. |
|
| Although geologic processes had destroyed all rocks from so long ago, the resistant zircons passed from one rock cycle to the next. |
|
| A handful of samples older than 4 billion years have been found in Canada and Australia, where they have been recycled through numerous violent iterations of the rock cycle. |
|
| Over the course of time, rocks can transform from one type into another, as described by the geological model called the rock cycle. |
|
| The process in the rock cycle which forms shale is called compaction. |
