What else can I help you with?
What is the term for an igneous pluton that occurs in an orientation that is discordant with the bedding surfaces of adjacent sedimentary rocks?
it is called a 'dike'
Are sills and dikes an example of intrusive igneous activity?
Yes they are. Dikes are tabular discordant bodies that are produced when magma is injected into fractures and Sills are tabular plutons formed when magma is injected along sedimentary bedding surfaces.
Why does it take thousands or millions of years to create sedimentary rocks when it may only take minutes to form igneous-?
It takes a long time for sedimentary rocks because the rocks have to break down in small pieces. The rocks are from the surfaces or the crust.
Is cross-beds a sedimentary structure?
Yes, cross-bedding is a sedimentary structure formed by the deposition of sediment in inclined layers, often caused by the migration of sand dunes or ripples. This structure is common in environments with flowing water or wind.
What are the principles of seismic stratigraphy?
Seismic stratigraphy is a geologic approach to the interpretation of seismic data, allowing their application based on physical stratigraphy. Primary seismic reflections parallel the surface and nonconforming surface of the strata.
What is the term for an igneous pluton that occurs in an orientation that is discordant with the bedding surfaces of adjacent sedimentary rocks?
it is called a 'dike'
What are the two proximal surfaces?
these are the surfaces on a tooth, which are in contact with the adjacent teeth. there are 2 proximal surfaces, namely mesial and distal. the former is towards the midline and the latter is away from the midline.
What is newton ring?
Newton's rings is a phenomenon when an interference pattern is created by the reflection of light between two surfaces. The surfaces are a spherical surface and an adjacent flat surface.
Is a cross bed sedimentary structure?
Cross-beds are horizontal units that are internally comprised of inclined layers. It is a sedimentary structure that forms during deposition on the inclined surfaces of bedforms.
Are sills and dikes an example of intrusive igneous activity?
Yes they are. Dikes are tabular discordant bodies that are produced when magma is injected into fractures and Sills are tabular plutons formed when magma is injected along sedimentary bedding surfaces.
Which is the splitting of a mineral along smooth flat surfaces?
Slate is a sedimentary rock that can be split horizontally to produce smooth flat surfaces that is often used as a roofing material.
What are expanded ends of bones that form joints with adjacent bones?
The expanded ends of bones that form joints with adjacent bones are called articular surfaces. These surfaces are covered with a layer of smooth cartilage to reduce friction and allow for smooth movement within the joint.
Why does it take thousands or millions of years to create sedimentary rocks when it may only take minutes to form igneous-?
It takes a long time for sedimentary rocks because the rocks have to break down in small pieces. The rocks are from the surfaces or the crust.
Is cross-beds a sedimentary structure?
Yes, cross-bedding is a sedimentary structure formed by the deposition of sediment in inclined layers, often caused by the migration of sand dunes or ripples. This structure is common in environments with flowing water or wind.
what junction of two tooth surfaces is a?
A junction of two tooth surfaces is called an embrasure. Embrasures are the V-shaped spaces formed between adjacent teeth. They play a role in maintaining proper gingival health and also help in self-cleansing of the teeth during activities like chewing.
How many horizontal and vertical surfaces does a cube have?
The answer depends on the orientation of the cube. If it is balanced on an edge or a vertex it has no horizontal or vertical faces. If it is resting on a face then it has 2 horizontal and 4 vertical faces.
What are the types of sedimentary structures?
The main types of sedimentary structures include bedding (layering), cross-bedding (inclined layers within a larger layer), ripple marks (small wave-like patterns on surfaces), mud cracks (polygonal patterns as mud dries), and fossils (remains or traces of ancient organisms).
