As a wave begins to feel the bottom near a shoreline, its wave height (D) increases and its wavelength decreases. This occurs due to the interaction of the wave with the ocean floor as it approaches the shore.

The water depth decreases, causing the wave to slow down and the energy to be compressed into a smaller space. This results in the wave height increasing, making the wave steeper. Simultaneously, the wavelength, which is the distance between consecutive crests, decreases because the waves are compressed together as they slow down.

This phenomenon is known as wave shoaling and it ultimately leads to wave breaking as the waves become too steep to maintain their shape, causing them to collapse and dissipate their energy on the shoreline. Hence, D is the correct option.

It would be surprising to find large fish-like organisms with rapid metabolism on Europa due to several factors:

Harsh Environment: Europa, one of Jupiter's moons, is covered by a thick ice crust, beneath which lies a global subsurface ocean. This ocean is believed to be kept in a liquid state by tidal heating caused by Jupiter's gravitational pull. However, the conditions in this subsurface ocean are extreme, with extremely low temperatures, high pressures, and limited access to energy sources. Such harsh conditions are not conducive to supporting large, complex organisms with high metabolic rates.

Limited Energy Sources: Europa's subsurface ocean lacks sunlight, which is a primary energy source for photosynthesis-based ecosystems on Earth. Without sunlight, alternative energy sources would be needed to support a complex food chain. While some potential energy sources could exist, such as hydrothermal vents or chemical reactions, they are likely limited and may not provide sufficient energy for large fish-like organisms with rapid metabolisms.

Lack of Oxygen: Oxygen is a vital component for organisms with high metabolic rates, as it serves as a key element for energy production. However, the availability of oxygen on Europa's subsurface ocean is uncertain. It is speculated that any available oxygen might be limited and mainly dissolved in the icy crust or in forms other than molecular oxygen, making it challenging to support oxygen-dependent large organisms.

Water uptake and transport in plants occur through a specialized tissue called xylem. The process begins with water absorption by the roots.

The roots, equipped with root hairs, increase their surface area to enhance water absorption. This process relies on osmosis, where water moves from areas of lower solute concentration (root hairs) to higher solute concentration (root cells). Once inside the roots, water is transported upwards through the xylem vessels. The movement of water through the xylem is primarily driven by transpiration, the loss of water vapor through the stomata in leaves. As water evaporates from the leaf surface, it creates a negative pressure (tension) in the xylem, known as the transpiration pull. This negative pressure, combined with cohesion and adhesion forces, helps water molecules to form a continuous column from the roots to the leaves. Cohesion refers to the attraction between water molecules, while adhesion refers to the attraction between water molecules and the walls of the xylem. Together, cohesion and adhesion allow water to be pulled up through the xylem vessels, against gravity, in a phenomenon known as capillary action. Ultimately, this process of water uptake and transport by plants ensures the delivery of water and dissolved nutrients to all parts of the plant, supporting its growth and survival. Additionally, transpiration helps to regulate plant temperature and plays a crucial role in the water cycle, influencing local and global climate patterns.

These combined processes of erosion on the outer bank and deposition on the inner bank gradually increase the lateral extent of the floodplain of a meandering stream over time.

Lateral erosion:

When a meandering stream bends, water flow is concentrated on the outer banks of the meander, resulting in increased erosion forces on that side. Water flows faster on the outer banks, and processes such as hydraulic action and abrasion increase bank erosion. Over time, this lateral erosion causes the meander to shift sideways, widening the floodplain.

Deposition on point bar:

Erosion occurs on the outer banks and deposition occurs on the inner banks of the meander. Due to the slow flow of water on the inner bank, sediment settles and accumulates, forming a point bar. Point bars are sedimentary landforms that accumulate over time and contribute to floodplain expansion.

The lower atmosphere typically has a steeper environmental lapse rate in the middle of the day because of increased solar heating.

During the middle of the day, the sun is at its highest point and emits the most heat, causing the Earth's surface to warm up. This process is called solar heating. As a result, air near the surface gets warmer and expands, becoming less dense. The warmer air then rises, creating convection currents. The environmental lapse rate (ELR) is the rate at which the air temperature decreases with increasing altitude.

Since the surface air temperature increases in the middle of the day due to solar heating, the difference between the surface temperature and the temperature at higher altitudes becomes greater. This leads to a steeper ELR during the middle of the day compared to other times.
