Explanation:
Basin or flooding mathod - involves the seasonal flooding of the nearby lands in the Nile Valley during which the flood water is trapped and cannot flow back into the Nile Valley
(ii) Perennial Method - involves the damming of rivers to create artificial reservoirs which can supply water to irrigation canals at any time of the year
(iii) The Shaduf Method - The oldest method during which farmers collect water from river channel, either with a bucket or a water bag, and pour it on their farms.
(b) Reasons for irrigation agriculture in Nile valley are:
(i) To supply water to the soil as little or no rainfall is experienced around these areas
(ii) To fight drought as Egypt experiences desert climate
(iii) To produce crops all year round.
(c) Problems associated with irrigation agriculture in the Nile Valley are:
(i) There is the problem of fluctuation in the level of water used for irrigation purposes
(ii) Presence of excess of mineral salt like sodium which are injurious to plant growth

describe and explain the characteristics of a stevenson screen
Answer:
Robert Louis Stevenson, in full Robert Louis Balfour Stevenson, (born November 13, 1850, Edinburgh, Scotland—died December 3, 1894, Vailima, Samoa), Scottish essayist, poet, and author of fiction and travel books, best known for his novels Treasure Island (1881), Kidnapped (1886), Strange Case of Dr. Jekyll and Mr. Hyde (1886), and The Master of Ballantrae (1889).
The Stevenson screen is painted white to refract the sun's rays more effectively.
What is Stevenson screen?Stevenson's screens are indeed painted white to refract the sun's rays more effectively. The skylights sides allow air to circulate around the thermometers. A psychrometer generator that pushes external air across the equipment inside helps the airflow in some places.
Its goal is to offer a consistent environment for measuring temperature, humidity, dew point, and atmospheric pressure.
A Stevenson screen's aim is to protect thermometers against precipitation and direct sunlight from outside sources, while enabling air to move freely around them. As a result, the screen provides a virtually unified enclosure that is the same temperatures as the air outside.

why is the ocean across heavier than the continental crust
plz explain and I iwll give u branist and rate u 5 star and also follow u plz help me
Explanation:
Layers that are less dense, such as the crust, float on layers that are denser, such as the mantle. Both oceanic crust and continental crust are less dense than the mantle, but oceanic crust is denser than continental crust. This is partly why the continents are at a higher elevation than the ocean floor.
Analise as alternativas sobre as características dos continentes terrestres e marque a única alternativa INCORRETA: * a) A Asia é o continente mais extenso, além de abrigar o maior contingente populacional. b) O continente americano é subdividido em América do Norte, América Central e América do Sul. c) A Oceania é o menor continente terrestre. d) Os países da Europa apresentam os mais elevados Índices de Desenvolvimento Humano (IDH) do planeta. e) A Africa apresenta diversos problemas socioeconômicos (subnutrição, desemprego, alta taxa mortalidade infantil, etc.), sendo o único continente com baixo padrão de vida.
Answer:
La opción incorrecta es D. Si bien es cierto que África presenta diversos problemas socioeconómicos, no es cierto que se trata del único continente con bajo nivel de vida.
Así, si bien la mayoría de los países africanos están sumidos en la pobreza, esta condición se encuentra en todos los continentes, con ejemplos como Ucrania o Moldavia en Europa, Haití o El Salvador en América, Afganistán o Birmania en Asia, o las Islas Salomón en Oceanía.

1-cite evidencias de que a milhoes de anos areas pode ter havido um supercontinente:o Pageia (obs:nao chute a resposta e nao Como que a resposta erranda pelo Amor de Deus)
Answer:
Pangea es el supercontinente que existió hace 250 a 210 millones de años, desde que se originaron todos los continentes actuales. Pangea estaba rodeada por un océano, Panthalassa. Pangea era una gran masa de tierra que finalmente se rompió por la tectónica de placas.
Durante el Jurásico, Pangea comenzó a desintegrarse. Primero, se formó una brecha de tres brazos entre lo que se convertiría en los continentes de África, América del Sur y América del Norte. La actividad volcánica creó una cuenca que luego se convertiría en el Océano Atlántico. Pangea se dividió primero en dos paleocontinentes, Laurasia y Gondwana (América del Sur siguió siendo parte de Gondwana durante algún tiempo). Después de eso, ambos paleocontinentes se dividieron aún más en los continentes de hoy.

Answer:
1. Complex fault interaction, 2. Atlantic ocean, 3. divergent plate boundaries and mid oceanic ridges, 4. Rate of movment is 1 cm per year due to rapid spreading of lavas. 5. Upwelling of magma, 6. faults, folds and volcanism.
Explanation:
The location of South America influences the development of earthquakes. Having s narrow continental shelf the plates of pacific and south America collide with each other. The mid oceanic ridge marks the new oceanic crust that is continuously being created as plate expand and the lithosphere becomes cooler. The presence of the divergent plate boundaries leads to their creation. The rate of movment of the plate is about 1 cm per year.Are the prevailing winds winds that always blow in a certain direction?
Answer:
Prevailing winds are winds that blow from a single direction over a specific area of the Earth. Prevailing winds blow east-west rather than north-south. This happens because Earth's rotation generates what is known as the Coriolis effect

Changing Agricultural Practices: ...
Explanation:
pls mark me as brainlist
The impact of human activities on soil are that some human activities have clear direct impacts.
These include land use change, land management, land degradation, soil sealing, and mining. The intensity of land use also has a great impact on soils.
Measures to conserve it include crop rotation, cover crops, conservation tillage and planted windbreaks
What is land degradation?Land degradation is a process in which the value of the biophysical environment is affected by a combination of human-induced processes acting upon the land.
It is viewed as any change or disturbance to the land perceived to be deleterious or undesirable.
Natural hazards are excluded as a cause; however human activities can indirectly affect phenomena such as floods and bush fires.
It is estimated that up to 4% of the world's agricultural land is seriously degraded.
What is crop rotation?Crop rotation is the practice of growing a series of different types of crops in the same area across a sequence of growing seasons. It reduces reliance on one set of nutrients, pest and weed pressure, and the probability of developing resistant pests and weeds.
A well-designed crop rotation can reduce the need for synthetic fertilizers and herbicides by better using ecosystem services from a diverse set of crops. Additionally, crop rotations can improve soil structure and organic matter, which reduces erosion and increases farm system resilience.

Which US state is losing land at a faster rate than anywhere else on the planet? At what rate?
Answer:
The Mississippi River Delta and coastal Louisiana are disappearing at an astonishing rate: a football field of wetlands vanishes into open water every 100 minutes. Since the 1930s, Louisiana has lost over 2,000 square miles of land, an area roughly the size of Delaware. Many factors have contributed to this collapse.
Figure 1 shows a seaside cliff. Figure 2 shows the same cliff after a short period of time has passed. What caused the change from figure 1 to figure 2 A.Rainfall only B.Ocean waves only C.Wind D.Rainfall and ocean waves
Answer : B
Explanation: the change is caused by erosion that is caused by strong ocean waves bashing up against the cliff.
Answer:
The correct answer is D) Rainfall and Ocean waves.
Explanation:
The diagram indicated is a perfect example of coastal erosion.
Coastal erosion happens when land is lost or displaced. This can be short-term or long-term and may involve the elimination of sediment and rocks along the coastline resulting from the action of waves, currents, tides, wind-driven water, waterborne ice, or other impacts of storms.
The four main stages of coastal erosion are corrosion, abrasion, hydraulic action, and attrition.
The United States for instance experiences a lot of coastal erosion in all its regions. More specifically, barrier islands in the southeast and the Great Lakes record 25 feet and 50 feet recession rates respectively.
