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

(iii) Over-flooding could be disastrous

(iv) Construction of many dams disturbs normal flow of water.

Answer:

The tectonic plates are always slowly moving, but they get stuck at their edges due to friction. When the stress on the edge overcomes the friction, there is an earthquake that releases energy in waves that travel through the earth's crust and cause the shaking that we feel.

Answer:

Natural se encuentra entre comillas porque en realidad el desastre no es provocado por la naturaleza, es decir, que no es natural sino que es una consecuencia del mal uso de los recursos naturales, de la degradación del ambiente para satisfacer necesidades inmediatas en donde no se toma en cuenta el daño que estamos generando. Este daño se acumula e incrementa nuestras vulnerabilidades o potencia las amenazas, por ende los desastres no son naturales sino que son causados por el hombre.

Explanation:

Podemos deducir que la palabra natural se encuentra entre comillas al leer "vamos lentamente degradando el ambiente que nos rodea, incrementando nuestras vulnerabilidades o potenciando amenazas..." o "Las acciones que realizamos sobre nuestro medio, el uso o el desecho que hacemos de los recursos naturales...este manejo genera efectos que se van acumulando." En estas líneas se evidencia que los desastres naturales en realidad no son causados por la naturaleza sino que son una consecuencia del hombre por utilizar mal los recursos naturales y no cuidar el ambiente.

Answer:

A

Explanation:

The Allies defeated a major German commander: the battle of El Alamein significant. Thus, option A is the correct option.

Axis (German and Italian) forces of the Panzer Army Africa, which included the Afrika Korps under Field Marshal Erwin Rommel, and Allied (British Imperial and Commonwealth) forces of the Eighth Army under General Claude Auchinleck fought in Egypt in the First Battle of El Alamein (1–27 July 1942), a battle of the Second World War's Western Desert campaign.

The British stopped the Axis forces from entering Egypt again. Axis positions adjacent to El Alamein were perilously close to Egypt's ports and towns, the bases used by the Commonwealth troops, and the Suez Canal. El Alamein was just 106 kilometers (66 miles) from Alexandria. However, the Axis troops couldn't stay in El Alamein permanently because they were too distant from their headquarters in Tripoli, Libya.

Answer:

Ottawa

Explanation:

Answer:

By providing information about tectonic plates.

Explanation:

The location or position of earthquake provide information about the presence of tectonic plates. The sliding of plates over one another is the main and single cause of earthquake. Continental drift is also the consequence of the movement of the plates which divides a single large continent into seven small continents so we can conclude that the location of earthquake provides evidences that supports the plate tectonics hypothesis.

Answer:c

Explanation:

Answer:

- Continental climates are found in the Northern Hemisphere, but not the Southern Hemisphere.

- Climate and bioregion play a significant role in human settlement patterns.

- There is a strong correlation, and possibly even a causal relationship, between climate and bioregion.

Explanation:

- Climate plays an important role in the location of plants and animals that in turn are crucial components of a bioregion.

- The Population Density map shows human settlement patterns. These patterns are consistent with the patterns on both the climate and bioregion maps.

- The color associated with the continental climate is blue. The color blue is found in the Northern Hemisphere but not the Southern Hemisphere.

Explanation:

we depend on them for drinking water

they are home to lots of species

they are the source of our irrigation for agriculture

All of the above are reasons why freshwater biomes are important.

Although freshwater biomes cover less than 1% of the Earth's surface, they are important because fresh  water is the lifeblood of our planet they are the source of our irrigation for agriculture , are home to lots of species, we humans depend on them for drinking.

Fresh water is any naturally occurring liquid or frozen water containing low concentrations of dissolved salts and other total dissolved solids.

Fresh water is vital to life and yet it is a finite resource. Although critical to natural and human communities, fresh water is threatened by a myriad of forces including overdevelopment, polluted runoff and global warming.

With this in mind, WWF partners with communities, businesses and others to decrease pollution, increase water efficiency and protect natural areas to ensure enough clean water exists to conserve wildlife and provide a healthy future for all.

Answer:

135°

Explanation:

The measure of angle DCU is 135°.

This is because angle DCU is the combination of a square and a triangle.

One of the angles of the square is 90° + 45° which is the value of one of the angles of an isosceles triangle.

= 135°

Assuming Square ABCD and isosceles triangle BUC are drawn to create trapezoid AUCD. The measure of angle DCU is 135°.

ΔDCB=90°

ΔCBU=90°

Hence:

ΔBCU=ΔBUC

ΔBCU=(180°-90°)/2

ΔBCU=45°

Measure of  angle DCU:

ΔDCU=ΔDCB+ΔBCU

ΔDCU=90°+45°

ΔDCU=135°

Inconclusion the measure of angle DCU is 135°.

Answer: Red dwarfs

Explanation:

Red dwarfs are thought to be the coolest star out of the rest. They are also the smallest. Because they are so cool, their luminosity is low as well on account of the fact that relatively speaking, the fusion taking place on their surface is little.

Red dwarfs are the most numerous star in the universe and the most numerous in the Milky Way galaxy as well. We just can't see them with out naked eyes because of their low luminosities.

Both types of food can require fewer pesticides. This is because genetically modified crops can be engineered to resist pests, reducing the need for pesticide application, while organic farming methods focus on natural pest control and avoiding synthetic pesticides. Therefore, option A is correct.

Pesticides are substances or chemicals used to control or eliminate pests, including insects, weeds, fungi, and other organisms that can damage crops, plants, or cause harm to humans and animals. These chemicals are applied to agricultural fields, gardens, or other areas to protect plants and crops from pests, prevent diseases, and enhance productivity.

Pesticides come in various forms, including insecticides, herbicides, fungicides, and rodenticides, each targeting specific types of pests. They can be synthetic (chemically produced) or derived from natural sources. Pesticides work by disrupting the physiology or life cycle of the target pests, inhibiting their growth, or causing their death.

While pesticides can be effective in pest control, their use raises concerns about potential adverse effects on human health, non-target organisms, and the environment. Proper and responsible use of pesticides, including following safety guidelines and regulations, is essential to mitigate these risks.
