Absence of sedimentary rocks = passage of time because over time, sediment breaks down and forms with the earth (land, sea, mountains)
If erosion did not occur, weathered rock material would not be broken down and transported to form new sedimentary layers. This would disrupt the rock cycle by preventing the formation of sedimentary rocks, which play a key role in the cycle's processes of deposition, burial, and lithification. Additionally, lack of erosion would limit the exposure of underlying rocks, hindering the process of uplift and the formation of metamorphic rocks.
Indications that a mountain range was not formed by subduction include the absence of volcanic activity, lack of deep oceanic trenches nearby, and the presence of sedimentary rocks instead of volcanic rocks. Additionally, the orientation of the mountain range and the type of rocks present can provide clues about the geological processes involved in its formation.
If erosion did not occur in the rock cycle, weathering and transportation of rock material would not happen efficiently, leading to a lack of sediment deposition and formation of new sedimentary rocks. This would disrupt the cycle, affecting the overall geologic processes and the formation of different types of rocks.
Shale usually crumbles easily because it is composed of fine-grained clay minerals that lack cohesion. The rock's sedimentary nature means it has undergone compaction and cementation relatively less than harder rocks like sandstone or limestone. This makes shale prone to breaking into small pieces when stressed.
Marble and quartzite are two examples of metamorphic rocks that lack banding and are massive. The lack of banding may indicate that the metamorphism may be due to a greater factor of heat than of pressure.
No sedimentary rocks are found yet. The reason is moon is lack of atmosphere.
No, sedimentary rocks are not classified as foliated. Foliation is a textural feature found in certain types of metamorphic rocks where minerals are aligned in layers or bands due to pressure and heat. Sedimentary rocks are formed by the accumulation and cementation of sediments and do not exhibit foliation.
Sedimentary rocks are typically dull in appearance due to their fine-grained texture and lack of large crystals. Shiny rocks are more commonly associated with igneous or metamorphic rocks that have undergone recrystallization processes.
A dis-conformity is an unconformity representing a period of erosion or lack of deposition in a sedimentary rock section.
Without an atmosphere or weather, a planet would not have sedimentary rocks. Sedimentary rocks form from the accumulation and compression of sediments by water, wind, or ice - processes that require an active atmosphere and weather system to transport the sediments.
If erosion did not occur, weathered rock material would not be broken down and transported to form new sedimentary layers. This would disrupt the rock cycle by preventing the formation of sedimentary rocks, which play a key role in the cycle's processes of deposition, burial, and lithification.

This sedimentary rock is quite beautiful, despite it's lack of value.
Yes, most rocks lack carbon-chain molecules in them and are generally considered inorganic. However, you may find some organic molecules in certain sedimentary rocks that contain fossils, such as limestone rock made from concreted shells of small aquatic molluscs.
nonfoliated rocks
Metamorphic rocks without visible layering are typically formed under conditions of high temperature and pressure that cause the minerals within the rock to recrystallize. This may result in a homogeneous texture without distinct layers or bands. These rocks may still exhibit foliation or other textures that indicate their metamorphic origin, even if they lack visible layering.
