Rank the following steps describing how a clastic sedimentary rock forms from its pre-existing parent rock.
1. weathering
2. erosion
3. transportation
4. deposition
5. lithification
Weathering, erosion, transportation, deposition, and lithification are the five steps how a clastic sedimentary rock forms from its pre-existing parent rock.
The five steps in the development of a clastic sedimentary rock from its pre-existing parent rock are eathering, erosion, transportation, deposition, and lithification.
The production of clastic sedimentary rocks begins with weathering. The breaking down of the parent rock into smaller fragments as a result of wind, water, and temperature changes is known as weathering.
The second stage of the development of clastic sedimentary rocks is erosion. Smaller fragments of the parent rock are removed from the surface during erosion and carried to new areas by the force of wind, water, and ice.
The third stage of the creation of clastic sedimentary rocks is transportation. Moving the smaller fragments of the parent rock from one place to another is referred to as transportation.
The fourth stage of the creation of clastic sedimentary rocks is deposition. Smaller fragments of the parent rock are deposited in a new area throughout the deposition process.
The fifth and last step in the production of clastic sedimentary rocks is lithification. Lithification is the process of compacting and cementing the tiny fragments of the parent rock to create a solid rock.

a break in the geologic record created when rock layers are eroded or when sediment is not deposited for a long period of time.
A gap in the geologic record, also known as an unconformity, is a break in the sequence of rock strata produced by erosion, non-deposition, or a combination of the two.
Unconformities might be erosional or non-depositional in nature. A record gap results from the erosion of rock strata, which is what causes an erosional unconformity. An unconformity that is not caused by sediment deposition does not result in the formation of new rock strata. There are several reasons for this, including a change in the temperature, a reduction in the sediment supply, or an increase in sea level.
Unconformities are significant identifiers in the geologic record because they allow geologists to estimate the age of the rocks in a specific location. They also provide us with hints about prior habitats and historical events.

Why does the wind at A change direction from south east to south west
The wind at a change direction from South East to South West due to Coriolis effect.
In most cases, the winds that prevail blow from east to west rather than from north to south. The Coriolis effect is responsible for this phenomenon, which takes place as a direct result of the rotation of the Earth. Because of the Coriolis effect, wind patterns in the Northern Hemisphere rotate counter-clockwise, whereas wind patterns in the Southern Hemisphere rotate clockwise.
A cyclone is a low-pressure phenomenon that draws air into its center, often known as its "eye." Fluids coming from high-pressure systems in the Northern Hemisphere go to the right, passing low-pressure systems on their way. When air masses are pulled into cyclones from all directions, they are deflected, and this gives the impression that the storm system, in this case a hurricane, is rotating in the opposite direction of clockwise. Currents are deflected to the left in the Southern Hemisphere because to the Earth's tilt. As a direct consequence of this, storm systems appear to rotate in a clockwise direction.

True. The Chicxulub crater is a massive impact crater beneath Mexico's Yucatán Peninsula.
One of the biggest known impact craters on Earth, the crater is thought to measure 180 kilometres (110 miles) in diameter. It is thought to have been created 66 million years ago by the collision of an asteroid or comet.
At the end of the Cretaceous epoch, the mass extinction of dinosaur species is largely believed to have been caused by this event. The crater is thought to have been produced by an asteroid or comet with a diameter of 10 to 15 kilometres (6 to 9 miles) striking the Earth at a speed of 20 kilometres per second (45,000 mph).
The heat from the collision destroyed the asteroid or comet and melted the rocks, producing a huge cloud of dust that obscured the sun and drastically reduced temperatures.

what are the three major types of fault boundaries?
Divergent boundaries — where new crust is formed as the plates pull apart.
Convergent boundaries are formed when one plate dives beneath another.
Transform boundaries — where the plates slide horizontally past each other, neither producing nor destroying crust.
Two tectonic plates moving horizontally in opposite directions away from a divergent boundary form a transform fault. As the plates move against each other, they create a lot of friction. Because the crust is rough, it will become stuck and create pressure. When the pressure becomes excessive, the energy is released, resulting in an earthquake.
A transform fault is a strike-slip fault that connects two tectonic plates moving away from a divergent boundary in opposite directions. San Andres Fault, Alpine Fault, and North Anatolian Fault are a few examples.

where would you expect terrestrial planets to form in the solar nebula?
Terrestrial planets are expected to form closer to the sun in the solar nebula.
This is because the temperatures are higher closer to the sun, leading to the formation of rocks and metals. As a result, the building blocks for terrestrial planets, such as silicates and metals, would be more abundant in this region.
Additionally, the gas and dust particles are denser closer to the sun, providing more material for the planets to form. Conversely, the outer regions of the solar nebula are colder and have more gas, leading to the formation of gas giants like Jupiter and Saturn.
The formation of planets depends on many factors, including distance from the star, temperature, and the abundance of building blocks, and the formation of terrestrial planets in the inner regions of the solar nebula is consistent with current theories of planetary formation.

how are fracture zones oriented relative to the axis of a mid-ocean ridge?
Fracture zones are orientated in relation to the mid-ocean ridge's axis because they run perpendicular to it.
A linear feature on the ocean floor called a fracture zone is created by the action of offset mid-ocean ridge axis segments. Fractures zones can be hundreds or even thousands of kilometres long. As a result of plate tectonics, they exist. When a transform fault is active, the lithosphere on each side of it shifts in the opposite direction; this is called strike-slip activity. Since both plate segments are moving in the same direction, the transform faults are seismically inactive, but fracture zones that extend past them provide signs of prior transform fault activity, particularly in the various ages of the crust on either side of the zone Although technically not "fracture zones," numerous transform faults linked with them are frequently regarded to informally as such.
