How is igneous rock transported?
Igneous rock is transported by wind or moving water until they are deposited in other regions where they settle in layers.
Unlike other types of plutons a dike forms?
A dike forms when magma is injected into a crack in the rock and solidifies underground. It is characterized by a tabular shape that cuts across existing rock layers. Dikes are typically composed of igneous rock, such as basalt or granite.
What causes igneous rocks to become sedimentary rocks?
If other layers of rock, dirt, dust, and sand are put on top of the igneous rock and the layers are compressed by their own weight, they become a single, unified layer of sedimentary rock. Simple Version: 1. Igneous rock 2. More rocks are put on the igneous rock. 3. The rock on top push down and squeeze the all of the layers into one layer.
What is the breaking or peeling away of rock in layers?
The breaking or peeling away of rock in layers is known as "exfoliation." This geological process occurs primarily due to temperature changes, where rocks expand when heated and contract when cooled, causing them to crack and separate in sheets or layers. Exfoliation is often observed in granite and other igneous rocks, where the outer layers can peel away, revealing the rock underneath. This phenomenon is a form of mechanical weathering that contributes to landscape evolution.
If a dike is present within a rock outcrop what is its age relationship with the other rock layers?
The dike is younger than the rock layers it intrudes into. Dikes form when molten rock (magma) is injected into fractures in existing rock layers and then solidifies, cutting across the surrounding rock. This means that the dike is a later geological event compared to the layers it cuts through.
What pluton is discordant?
plutons that thin in one direction as compared with other two dimensions.common ones are dykes.
Layers that act as though they communicate directly with each other across the network are called what?
Peers
What is the shape of graphite crystals?
Graphite crystals have a hexagonal shape due to the arrangement of carbon atoms in layers called graphene sheets. These sheets are stacked on top of each other, forming the distinct hexagonal shape of graphite crystals.
Why does mica break evenly along flat sheets?
Mica breaks along flat sheets because it has a layered structure with weak bonds between the layers. When stress is applied, these weak bonds allow the layers to easily slide past each other, resulting in the mica breaking evenly along the planes of weakness.
What can you determine from the principles of crosscutting relationships?
Layers that cut across the most other features are the youngest. (apex)
What do the principles of cross-cutting relationships teach us?
Layers that cut across the most other features are youngest.
