The type of unconformity, which is usually easiest to spot, since layers of sedimentary rocks are on top of igneous rocks without layers is called Disconformity.
What is an unconformity?
An unconformity is a contact between two groups of rock formations. An unconformity is a surface of erosion or non-deposition that separates younger from older rocks. A time gap or hiatus exists at the unconformity between the rock layers, indicating that some time has passed between the formation of the first group of rocks and the second group.
There are three types of unconformities: nonconformity, disconformity, and angular unconformity. An unconformity can be caused by tectonic events, sea-level shifts, or erosion, among other things.
A disconformity is an unconformity in which parallel layers of sedimentary rocks are separated by a break in sediment deposition or a layer of erosional material.
In a disconformity, the bedding planes of the strata above and below the unconformity are parallel, indicating a time gap in the sedimentary record.

based upon your analysis, most stratovolcanoes form in which tectonic setting? group of answer choices divergent boundaries oceanic-continental convergent boundaries mantle plumes (hotspots) all of the above
The correct option is All of the above i.e. D. Most stratovolcanoes form in convergent boundaries, which occur when two tectonic plates collide. This collision causes one of the plates to slide beneath the other, creating a subduction zone.
The subducting plate melts due to the extreme pressure and heat created from the collision, resulting in magma being forced upward to form a stratovolcano. Oceanic-continental divergent boundaries can also form stratovolcanoes, as the plate separation creates a rift zone.
Mantle plumes, also known as hotspots, can also form stratovolcanoes when a column of hot material from the mantle rises up through the Earth's crust, creating a weak area of the crust which can then be filled with magma. All of these tectonic settings can create stratovolcanoes. The correct option is All of the above i.e. D.

In an area of known past glaciation, hummocky topography most often results from debris deposited by melting glaciers.
Hummocky topography is a surface feature created when a glacier melts and recedes, leaving behind a series of small hills and valleys. This topography is formed when the glacier pushes rocks, soil, and other debris forward as it moves, creating a bumpy surface. As the glacier melts, the debris is left behind and forms these hummocks and mounds. In areas of known past glaciation, hummocky topography is one of the most common features that remain.
A hummock is a small hillock, knoll, or mound. A hummocky topography is one that contains such little hills and mounds. This condition usually results from ice movements and melting, as it can cause landmasses to rise, shift and reshape. Similarly, the hummocky topography that arises from glacial debris results from the material, including boulders, rocks, gravel, and sand, that was deposited by melting glaciers.
The debris is sorted based on its size, with larger rocks at the top and finer debris at the bottom. The hummocks are formed by the melting of the smaller debris, while the larger rocks are left behind as hillocks. These features are common in regions that were once under glaciers, as the melting and erosion of the ice left behind these deposits.

what evidence suggests that water might still flow at or beneath the martian surface today? why do we think that mars might still have subsurface liquid water today?
Evidence suggests that Mars might still have subsurface liquid water today due to spectral analysis of minerals on the Martian surface.
These spectral analyses show that there are hydrated minerals on the surface, which suggests that Mars has had liquid water in the recent past, and that it could still exist at or below the Martian surface. This is further supported by observations of features on the Martian surface that are similar to features on Earth that are caused by liquid water.
In addition, observations of the sub-surface temperatures of Mars by the InSight lander suggest that liquid water could still be present today. The temperatures in some areas are too high to be caused by ice, which suggests that they could be due to liquid water.

during the planet formation process, runaway growth of planetesimals is enabled by group of answer choices
During the planet formation process, the runaway growth of planetesimals is enabled by the gravity of the large planetesimals. The statement is very true.
The term planet formation is referred to the processes that resulted in the formation of planets. Planets are born from the same stuff as stars. The vast clouds of gas and dust in space are known as nebulae. The sun, planets, and all other stars in the universe began as a nebula.
The planet formation process begins with the development of planetesimals. Planetesimals are small, irregularly shaped bodies made up of rock and metal that orbit the sun. These planetesimals collided and adhered to one another, forming bigger bodies. These bigger bodies were then attracted to one another by gravity, eventually resulting in the formation of planets.
The larger planetesimals' gravity can attract and merge smaller ones, producing even larger planetesimals. When some planetesimals reach around the size of the Moon or Mars, their gravity becomes strong enough to pull in gas from the surrounding nebula, causing the planetesimal to develop into a planet.

what is the significance of numerous alternating layers of marine and continental formations found in a plateau? provides direct evidence for the theory of cyclic epeirogeny the sedimentary platform must have been elevated one time lack of highly deformed strata casts doubt on multiple cyclic movements
The alternating layers of marine and continental formations seen in a plateau are noteworthy because they give direct evidence for the notion of cyclic epeirogeny.
According to this view, plateaus and other high landforms are the consequence of periodic large-scale vertical motions of the Earth's crust.The sedimentary platform that makes up the plateau must have been uplifted and submerged throughout time as there are alternating layers of marine and continental formations. This is in line with the cyclic epeirogeny theory, which contends that the crust of the Earth experiences periodic elevation and subsidence.The hypothesis of many cyclic motions, however, is called into question by the absence of strongly deformed layers. If the layers had undergone multiple episodes of intense deformation, such as folding or faulting, it would be difficult to distinguish individual layers of sedimentary rock. As a result, the lack of significantly deformed strata shows that the vertical motions that produced the plateau may have been less abrupt and more gradual than previously believed.

A stream or river is a body of water flowing in a __________.
A stream or river is a body of water flowing in a channel.
A stream is a small river that can be crossed by wading or hopping from one bank to the other. If the stream is fed by underground water sources or has a large volume of water, it might be deep enough to require a bridge. The water in a stream or river usually flows downhill due to gravity, but it may also flow from high to low pressure or from an area of high elevation to one of lower elevation.
The movement of a river is aided by the slope of the ground, the size and position of rocks and other debris in its bed, and the amount and speed of water in the river. The soil composition and the landscape through which it flows will also influence the river's flow. The banks of a river or stream are often eroded by the water's movement, and the water may transport soil, rocks, and other debris downstream. This process aids in the formation of canyons, gorges, and other geologic formations.

how do metamorphic changes that take place due to recrystallization differ from those that happen due to pressure solution? match the changes to their correct process.
Answer: The metamorphic changes that take place due to recrystallization differ from those that happen due to pressure solution.
Explanation:
Some of the differences between the two processes of metamorphism are explained below:
Recrystallization: The process of changing the mineral structure and texture of a rock is known as recrystallization. Recrystallization is a process that occurs at high temperatures and pressures. The minerals in a rock can become unstable under these conditions and rearrange themselves to form new minerals with larger crystals. This leads to the formation of a new rock with a new structure and texture.Pressure solution: This is a process of metamorphism that occurs when rocks are subjected to pressure. When rocks are subjected to pressure, the mineral grains in them dissolve into each other. This process is called pressure solution. It is a process of metamorphism in which the minerals in a rock dissolve into each other as a result of the pressure that is being applied to the rock. This leads to the formation of a new rock with a new structure and texture.The metamorphic changes that take place due to recrystallization and pressure solution:
Recrystallization refers to alterations in the size, shape, and orientation of minerals within a rock, as well as the creation or modification of minerals.
Pressure solution leads to modifications in the shape and orientation of minerals in the rock, the establishment of a foliation or cleavage, and the arrangement of minerals along a particular plane or direction.

The Antarctic Ice Sheet is losing mass at an accelerating rate, and playing a more important role in terms of global sea-level rise. The Amundsen Sea sector of West Antarctica has most likely been destabilized. Although previous numerical modeling studies examined the short-term future evolution of this region, here we take the next step and simulate the long-term evolution of the whole West Antarctic Ice Sheet. Results show that if the Amundsen Sea sector is destabilized, then the entire marine ice sheet will discharge into the ocean, causing a global sea-level rise of about 3 m. We thus might be witnessing the beginning of a period of self-sustained ice discharge from West Antarctica that requires long-term global adaptation of coastal protection.
