A: The animals today that have characteristics similar to those of dinosaurs from the Mesozoic Era are birds.
B: The characteristics of mammals allowed them to survive when dinosaurs died out at the end of the Cretaceous period was that they were warm-blooded, they had variety of teeth, and had higher metabolism.
A: Birds are the closest living relatives of dinosaurs and have many characteristics similar to those of dinosaurs from the Mesozoic Era. For example, many birds have lightweight, hollow bones and some even have feathers, which were also present in some dinosaur species.
B: Mammals were able to survive when dinosaurs died out at the end of the Cretaceous period because they had certain characteristics that allowed them to adapt to the changing environment. Mammals are warm-blooded, which means that they can regulate their body temperature internally, unlike cold-blooded reptiles. This allowed them to survive in a wider range of environments, including colder climates.
Additionally, mammals have a wider variety of teeth than reptiles, which allowed them to adapt to different diets. Finally, mammals also have a higher metabolism than reptiles, which means they need to eat more often, but it also allows them to be more active and better at hunting prey.
These characteristics allowed mammals to diversify and evolve into a wide range of different species after the extinction of the dinosaurs.

Should we protect native British species against invasive species? Justify your view?
Answer:
I think yes, you should protect native British species because invasive species can be harmful to the land and they can destroy the envorment that the native species live in making the native species suffer and maybe go extinct. invasive species like the Asian carp, can also affect humans as well and have a domino effect on all surroundinglife around an invaded area. so yes, you should protect them.

How would uh convert it into a fertile farmland
Answer:
Water harvesting: Since the soil was eroded, they first set up water harvesting structures, such as swales, trenches, percolation tanks. These systems increased the efficiency of water use, recharged four existing borewells (which were not effective) and ensured a regular supply without taking from the reservoir.
Sapling plantation: Water harvesting is incomplete without planting. Saplings from government and private nurseries were used in the first plantation cycles. A nursery was set up to host young trees and plants which were later planted at Polam. The goal was to revive soils and life by planting diverse species.
Fencing: In an arid region, fires are common. To avoid damage, live fences were raised around the boundaries, and windbreaks such as huge teak trees were planted to brave the South wind blowing from the reservoir. Fruit trees have now fully reforested another 2 hectares acre of the farm. The fruit forest has become a new habitat for insects, animals and birds.
Regenerate through biodiversity: In the rest of the land, trees and plants have been scattered between local species, which adapt to the dry land climate, and tropical species. Although some died, diversification ensures that there is regeneration of life.
Animals: Animals playing a key role in regeneration. Chickens, bullocks and cows were integrated in the everyday activities. The chickens provide eggs and their excreta enriched compost. Bullocks are used for ploughing and sowing.
Local crops: Local crops such as millets, pigeon peas, green grams are also grown. Seasonal vegetables from the garden such as brinjals, curry leaves, cluster beans, rosella plants are used for daily consumption and will also be served to the 600 participants at the IPC.
If Si is the average salt content of the incoming seawater and So is the average salt content of the exiting surface water in an estuary, the fresh water in the exiting mixed water is ______.
If Si is the average salt content of the incoming seawater and So is the average salt content of the existing surface water in an estuary, the fresh water in the exiting mixed water is (Si - So)/Si.
What is salt content?Salt, commonly known as sodium chloride, is composed of roughly 40% sodium and 60% chloride. It is used to flavor food and as a binder and stabilizer. It also serves as a food preservative since germs cannot live in the presence of a high concentration of salt.It is often determined by ashing the meal at 500°C and then estimating the sodium content by spectrophotometry, using its distinctive light emission or absorbance in a flame (AAS, ICP, or flame photometer).(Si - So)/Si is the fresh water in the existing mixed water.Therefore, if Si is the average salt content of the incoming seawater and So is the average salt content of the existing surface water in an estuary, the fresh water in the exiting mixed water is (Si - So)/Si.

The three zones to be to be classified of a river system are as following:-
Zone of sediment production (Streams in the mountain)Zone of sediment transportation (River in between the mountain and shore)Zone of sediment deposition (Streams that end at the shore)Explanation:-Production of sediment will fall under initial zones. Sediment may be created in a variety of ways, such as when igneous and metamorphic rocks are exposed to wind and water and weather. decay of the wildlife and plants. However, the majority of sediments are produced when rocks are broken down by streams, rivers, and other moving bodies of water. Rocks may also be weathered extensively by wind. sediment formed by the weathering of rocks is found in the first zone.
The second zone will cover sediment transport. The slope (which may be caused by any type of landform) allows the produced sediment to flow and travel downhill, according to the diagram.
Under the third zone, sediment deposition occurs. Because the flow of the streams ceases at the bottom, all carried silt will be deposited there.

Southern California is famous for its wildfires, which are often exacerbated by the Santa Ana winds blowing through the canyons. What mass wasting event will later devastate the same fire-affected areas
The mass wasting event which will later devastate the same fire-affected areas is called Mudflows
Why do mudflows happen?
Mudflows occur when significant amounts of water collect to quickly erode soil on a steep slope. Mudslides happen when a lot of water builds up and quickly erodes the soil on a steep slope. As a result of heavy rain, for example, water seeps into the soil and separates the soil grains.
A muddy substance's starting point for flow is influenced by its particle size, water content, and topographical slope. In contrast to coarse sediment or a debris flow, shallower flows can transport fine-grained particles like mud or sand. A mud flow can start more easily when there is more water present (more precipitation or overland flow).
Coarser material may be swept up by a mud flow after it forms. Finer sediment and water that pools up behind the flowing front of the coarse-grained mudflow push the coarser silt that was taken up by the flow and often forms the front of a mudflow surge.

Gondwana moved northward during the Carboniferous, and periods of sea level rise/fall due to melting/advancing glaciers caused unique cyclic rock sequences of nonmarine and marine deposition. These are called cyclothems.
In geology, cyclothems are alternating stratigraphic sequences of marine and non-marine sediments, sometimes embedded with coal seams. Historically, the term was defined by European coal geologists working with coal pans formed during the Carboniferous and early Permian periods.
The deposit sequence has been exhaustively explored by petroleum geologists using geophysical profiles of continents and ocean basins. A common theory of basin-scale sedimentation is formalized under the name sequence stratigraphy.
Since the Carboniferous was a widespread ice age in the Southern Hemisphere, it is likely that several cyclothems formed as a result of oceanic regressions associated with the growth and collapse of ice sheets, respectively. A more common interpretation of the sequence gives rise to Milankovitch cycles.
