during fair weather, the net movement of sand perpendicular to shore is offshore (away from the beach).
During fair weather, the net movement of sand perpendicular to shore is offshore, which means it moves away from the beach. This phenomenon occurs due to a combination of factors related to weather and wave activity.
In fair weather conditions, waves approach the shore at an angle, which leads to a process called "swash and backwash." Swash refers to the water washing up onto the beach, carrying sand and other sediment with it. Backwash is the water flowing back down the beach, pulling sand and sediment back towards the ocean. When waves break at an angle, they create a zigzag pattern of sand movement, known as longshore drift. However, in fair weather, the dominant wave direction is typically perpendicular to the shore, minimizing the longshore drift effect.
The balance between swash and backwash results in the net movement of sand being offshore. To further explain, as waves break near the shore, their energy dissipates and the offshore-flowing currents carry the suspended sand and sediment away from the beach. This offshore movement of sand can lead to the formation of sandbars, which are underwater ridges of sand that parallel the shoreline.
In summary, during fair weather, the net movement of sand perpendicular to shore is offshore due to the combined effects of swash and backwash, wave angle, and offshore-flowing currents. This results in sand being transported away from the beach and can contribute to the formation of sandbars.

72) The main energy resources associated with marine sediments are petroleum and ________. A) coal
B) wind power
C) rare-earth elements
D) gas hydrates E) ethanol
Answer:
D.) Gas hydrates
Explanation:
Frost that forms on cold glass is created by the process of:
-sublimation.
-transpiration.
-freezing.
-deposition.
Frost that forms on cold glass is created by the process of D. Deposition.
Deposition occurs when water vapor in the air comes into contact with a cold surface, such as a glass window, and transforms directly from its gaseous state into solid ice crystals. This change of state skips the liquid phase, meaning that the water vapor does not condense into liquid water before freezing.
Instead, it solidifies directly onto the cold surface as frost. Deposition is the opposite process of sublimation, which involves a substance transitioning directly from a solid to a gas without passing through the liquid phase. In contrast, transpiration is the process by which plants release water vapor into the atmosphere, and freezing is the transition from the liquid phase to the solid phase.
While freezing is involved in the formation of frost, it is not the direct cause, as the water vapor bypasses the liquid state altogether through the deposition. Therefore, the correct option is D.

The cloud droplets in a cloud are formed by water vapor molecules and:
-ions.
-protons.
-other water vapor molecules.
-molecules of air.
-condensation nuclei.
Cloud droplets in a cloud are formed through a process called condensation, where water vapor molecules in the air cool and come together to form liquid water droplets.
The correct answer is e) condensation nuclei.
However, for condensation to occur, the water vapor molecules need a surface to gather around, which is provided by tiny particles called condensation nuclei. These condensation nuclei can be solid particles, such as dust, pollen, or pollution particles, or even liquid particles, such as tiny water droplets or ice crystals.
Condensation nuclei serve as the "seeds" around which the water vapor molecules can gather and form cloud droplets. Without condensation nuclei, the water vapor molecules would remain in the gaseous state and not form visible cloud droplets. Therefore, condensation nuclei are an essential component in the process of cloud formation, allowing cloud droplets to form and contribute to the formation of visible clouds in the atmosphere.

What would happen to the oceans if surface runoff and groundwater flow were reduced (for example, by the growth of ice sheets during an ice age)?
-The oceans would become bigger.
-The oceans would stay the same size.
-The oceans would become smaller.
If surface runoff and groundwater flow were reduced due to the growth of ice sheets during an ice age, C. the oceans would become smaller.
This reduction would result from the increased accumulation of water in the form of ice, leading to a decline in the amount of water available to replenish the oceans. Additionally, the expansion of ice sheets would trap more water on land, further decreasing the volume of water reaching the oceans.
With less surface runoff and groundwater flow, the overall global water cycle would be affected. The reduced input of freshwater into the oceans would likely lead to changes in ocean currents, salinity, and the marine ecosystem. Ocean currents, which play a vital role in distributing heat and nutrients across the planet, could become disrupted, leading to further climatic changes and potentially impacting the global climate system. Moreover, the decrease in the volume of the oceans would result in lower sea levels, which could affect coastal ecosystems and the distribution of landmasses.
In summary, a reduction in surface runoff and groundwater flow due to the growth of ice sheets during an ice age would lead to smaller oceans, influencing various aspects of the global environment, such as ocean currents, sea levels, and marine ecosystems. Therefore, the correct option is C.

True or False: The atmospheric temperature will always be less than or equal to the dew point
The given statement "The atmospheric temperature will always be less than or equal to the dew point" is true because since the dew point represents the temperature at which the air is saturated with water vapor, the atmospheric temperature must always be less than or equal to the dew point.
The temperature at which the air becomes saturated with water vapour and condensation forms is known as the dew point. When the temperature of the atmosphere equals the dew point, the air is said to be at 100% relative humidity.
When the temperature of the atmosphere falls below the dew point, the air can no longer hold all of the water vapour it contains, and some of it condenses into liquid water or ice.
This is why, on cool nights when the temperature falls below the dew point, dew or frost frequently accumulates on surfaces.

An unconformity in which the strata on either side are essentially parallel is termed a disconformity.
A disconformity is a type of unconformity that occurs between two parallel layers of sedimentary rocks of different ages. It represents a period of erosion or non-deposition, during which time the older rock layer was exposed to the surface and eroded while the younger layer continued to accumulate on top of it. Disconformities can be difficult to recognize because the layers above and below the unconformity appear to be parallel, making it hard to identify the gap in time represented by the missing layer. However, geologists can use a variety of techniques, including radiometric dating and fossil analysis, to determine the relative ages of the rocks and the time gap represented by the disconformity.

As liquid water is evaporated into the atmosphere, heat energy is:
-released by the evaporating water.
-absorbed by the evaporating water.
-absorbed by the surrounding air.
-given off by the water vapor.
-absorbed by the remaining liquid.
As liquid water is evaporated into the atmosphere, heat energy is B. absorbed by the evaporating water.
During evaporation, heat energy is absorbed from the surrounding environment, increasing the kinetic energy of the water molecules. As a result, the molecules with the highest kinetic energy are able to break free from the liquid's surface and become water vapor. This absorption of heat energy during evaporation is known as the latent heat of vaporization.
As the water absorbs heat energy and evaporates, the remaining liquid will often experience a cooling effect. This is because the molecules with the highest kinetic energy are the ones that escape into the atmosphere, leaving the lower-energy molecules behind. This cooling effect is utilized in many everyday applications, such as perspiration in humans, where the body produces sweat to help regulate temperature through evaporative cooling.
In summary, during evaporation, heat energy is absorbed by the evaporating water, allowing the water molecules to overcome intermolecular forces and transition from the liquid phase to the gaseous phase. This process also results in a cooling effect for the remaining liquid. Therefore, the correct option is B.

Erosion and deposition by water, wind, and ice are the principal processes that sculpt Earth's landscape. These natural forces have been at work for millions of years, gradually shaping the surface of our planet.
Erosion occurs when rocks and soil are worn away by the movement of water, wind, or ice. The force of these elements can break down rock formations and carry away sediment, gradually reshaping the landscape over time. Deposition, on the other hand, occurs when sediment is deposited in a new location by the same natural forces that eroded it. For example, wind can pick up sand from a beach and deposit it in dunes further inland. Similarly, water can carry sediment downstream and deposit it in a delta or floodplain.
Together, erosion and deposition work to create a diverse range of landforms, from towering mountains and deep canyons to rolling hills and sandy beaches. They also play an important role in the natural processes that sustain life on Earth, such as the cycling of nutrients and the formation of soil. However, human activity can also impact these natural processes, leading to increased erosion and changes in the landscape. It is important to understand the role of erosion and deposition in shaping our planet, and to work to minimize our impact on these delicate processes.
