Volcanic activity and creation of new ocean occur at mid-ocean ridges.

Mid-ocean ridges are divergent plate boundaries where two tectonic plates move away from each other. This movement causes magma from the mantle to rise and create new oceanic crust. The volcanic activity at mid-ocean ridges is responsible for the creation of new ocean floor. Earthquakes can also occur at mid-ocean ridges due to the movement of the plates, but they are not a defining characteristic of these boundaries. Subduction, where one plate is forced beneath another, does not occur at mid-ocean ridges as these boundaries are associated with seafloor spreading.

No, the above statement is false. A star system may undergo two or more supernova outbursts, but not nova outbursts.

A nova occurs in a binary star system where one star is a white dwarf and the other is a main sequence or giant star. The white dwarf accretes material from its companion, and when enough material accumulates on its surface, a thermonuclear explosion occurs, resulting in a nova outburst. However, this event does not cause the destruction of the white dwarf.

On the other hand, a supernova is a much more powerful and catastrophic event that occurs at the end of a massive star's life. When a massive star exhausts its nuclear fuel, it undergoes a core collapse, resulting in a supernova explosion. This event leads to the complete destruction of the star, leaving behind either a neutron star or a black hole.

While a star system can experience multiple nova outbursts if conditions are favorable, it is not possible for a star system to undergo multiple supernova outbursts. Supernovae are rare and typically mark the end stages of a massive star's life.

Along a boundary where crust is widening, a process called divergence occurs. As the crust moves apart, several geological phenomena take place.

Firstly, a rift forms, creating a gap or rift valley between the separating crustal plates. This rift is often accompanied by volcanic activity, as magma rises to the surface through the fractures in the crust. This leads to the formation of new volcanic features such as shield volcanoes or lava flows.

As the crust continues to separate, the rift valley widens, and the gap between the plates becomes filled with molten rock or magma. Over time, this magma cools and solidifies, forming new oceanic crust. This process is known as sea-floor spreading and results in the creation of new oceanic basins.

The widening of the crust along the boundary is a gradual process that can occur over millions of years. It leads to the formation of new oceanic crust and contributes to the continuous movement of the Earth's tectonic plates.

The daily cyclical pattern in river discharge is caused by factors such as snowmelt, evapotranspiration, groundwater influence, and human activities.

The regular repeating pattern of daily cyclical discharge in rivers can be attributed to a phenomenon known as diurnal or daily hydrological fluctuations. Several factors contribute to this pattern:

Snowmelt and Glacial Runoff: In regions with snow or glaciers, the daily temperature variation causes snow or ice to melt during the day, increasing the discharge. At night, with cooler temperatures, the melting process slows down, leading to decreased discharge.

Evapotranspiration: During the day, higher temperatures and sunlight promote evaporation from the river and surrounding vegetation. This reduces the amount of water in the river, resulting in lower discharge. At night, evaporation rates decrease, allowing discharge to increase.

Groundwater Influence: Groundwater contributes to river flow. During the day, evapotranspiration rates increase, leading to a drawdown of groundwater levels, which reduces river discharge. At night, with reduced evapotranspiration, groundwater levels rise, resulting in increased river discharge.

Human Activities: Human activities, such as water withdrawals for irrigation or industrial use, can also contribute to the daily cyclical pattern. Higher demand during the day leads to reduced river flow, while decreased demand at night allows for increased discharge.

It's important to note that the specific factors contributing to the daily cyclical pattern may vary depending on the geographical location, climate, and local hydrological conditions of a particular river.
