¿Qué dificultades y ventajas presentaban las características geográficas de la cuenca del Mediterráneo para la agricultura, las comunicaciones y el transporte, la vida cotidiana?
Answer:
Dificultades para agricultura:
Eventos de sequía muy marcadaPlagas y pestesSobredemandaVentajas para agricultura:
gran proporción de especies nativas con alto valor energético y potencial de domesticaciónclima costero templadoVentajas para comunicaciones y el transporte
Mar mediterráneo uniendo pueblosDesarrollo de la navegaciónAsentamientos en las zonas costerasIncremento de la comercialización e intercambio de productos y saberesExplanation:
En el área mediterranea existe una alta proporción de especies nativas con potencial de domesticación, entre las que se encuentran muchos pastos y mamíferos. De hecho, muchas de las especies cultivadas y comercializadas a nivel global en la actualidad provienen de pastos del mediterraneo.
En el clima mediterráneo, la estacionalidad es muy marcada en las caras oeste de los continentes. La estación seca ocurre durante el verano, y la estación húmeda ocurre durante el invierno.
En invierno, la tierra tiende a enfriarse más que el agua del océano, y los vientos del oeste traen a la costa aire cargado de humedad, que se condensan, y precipitan. En verano, la tierra está más caliente que el océano; los vientos del oeste soplan tierra adentro y se calientan en tierra, absorbiendo más humedad, y haciendo más secas las condiciones en tierra.
La estación seca es hostil debido a las elevadas temperaturas del verano. Los eventos de sequias, junto a la mayor tendencia de ocurrencia de plagas que ataquen los cultivos, sumada a la sobredemanda, hacen de la agricultura una actividad dificil.
Aún así, fue el clima costero templado el que favoreció el desarrollo de la agricultura. La producción de trigo, vino o aceite de oliva, entre otros productos de alto valor energético, generaron un gran impacto económico, incrementando el comercio y la comunicación dentro de la zona mediterránea.
La tendencia de los pueblos a ubicarse cerca del agua distó mucho de ser una limitación. Desarrollaron la navegación a través de la que pudieron incrementar el comercio e intercambio cultural entre pueblos. Sumado a ello, este tipo de transporte facilitó la colonización de nuevas áreas.
En la cuenca del Mediterraneo se encuentra la Medialuna Fertil, que porbablemnte haya sido el primer centro de domesticación. Es aquí donde comenzaron la domesticación de distintas especies vegetales y de algunas especies animales.

Define the term climate change and briefly explain why it is important
Answer:
Climate change is the long-term alteration of temperature and typical weather patterns in a place. Climatic Change is important since it helps determine future climate expectations. Through the use of latitude, one can determine the likelihood of snow and hail reaching the surface. You can also be able to identify the thermal energy from the sun that is accessible to a region.

Weather is a result of different air masses coming in contact with each other. Use the fronts and pressure systems on the weather map to identify the weather condition that is labeled correctly.
Answer:
Mild weather.
Explanation:
Mild weather is the weather that labeled correctly because the regions nearer to the ocean or sea have mild weather condition. Due to near of water, the coastal regions experiencing warmer winters and cooler summers as compared to regions that are situated far from the ocean or sea. This is a result of ocean temperatures that taking longer to warm up and cool down than the adjacent landmass.

A boy is flying a kite. His kite string is extended 50 meters long. The boy is 1.7 meters tall, and the angle of elevation of the kite to the boy's hands is 12°. How high is the kite flying above the ground?
Answer:
12.1 meters
Explanation:
Please check the attached image for a diagram of the question
We are given the value of the hypotenuse and we are to determine the value of the opposite side. Thus, we would use sin
Sin = opposite / hypotenuse
sin 12 = opposite / 50
0.2079 = opposite / 50
opposite = 0.2079 x 50 = 10.4 meters
height of the kite above the ground = 10.4 + 1.7 = 12.1 meters
Describe how the rotation of Earth around its own axis and its revolution around the sun affect sunrise and sunset. Explain why will this be different from outer space.
Answer:
since earth rotates on a tilted axis we experience night and day, and also different seasons. while being tilted on our axis we can experience longer days and shorter night when pointing towards the sun (summer), and shorter days and longer night pointing away from the sun (winter). you would experience a difference in space because you wouldn't be rotating on a axis any more. you would experience the same night and day patterns every day.

Explain different methods used to prevent salinity?
Explanation:
Type of salinity and their prevention
There are different types of salinity, each with different causes and varying treatment.
Dryland salinity is the accumulation of salts in the soil surface and groundwater in non-irrigated areas. It is usually the result of three broad processes:
groundwater recharge (or deep drainage)
groundwater movement
groundwater discharge.
Often it results from replacing deep-rooted native vegetation with shallower-rooted crops and pastures, which take up less water. Unused rainwater leaks into the ground causing groundwater to rise and dissolve salts stored deep in the soil. The salty water may:
rise to the surface causing waterlogging and/or scalding
emerge at the break of a slope as seeps
flow over the surface or underground into streams and rivers.
Irrigation salinity
Irrigation salinity is the rise in saline groundwater and the build-up of salt in the soil surface in irrigated areas. It is caused by using large volumes of irrigation water that locally raise groundwater levels and mobilise salt. Irrigation salinity is made worse when water used to irrigate is from salty sources.
Irrigation salinity can be controlled by using water efficiently. Crops should receive only the amount of water they can actually use. Reducing water usage in irrigated areas generally requires changes to irrigation infrastructure and technology, and better matching of crops to soil types.
Urban salinity
Urban salinity is a combination of dryland and irrigation salinity processes and is mainly caused by rising groundwater bringing salts to the land surface. The rise in groundwater is caused by blocked or changed natural drainage paths due to:
urban development
over-watering of parks and gardens
leaking pipes, drains and tanks.
In the urban environment, other sources of salt that can contribute to urban salinity include:
effluent
building materials
industrial waste water
fertilisers and chemicals.
Industrial salinity
Many industrial processes have the potential to increase salinity levels in rivers. Examples are:
saline water from mines (working and abandoned) from groundwater seepage and from rainwater coming into contact with mine workings or spoil
discharged cooling water from coal-fired power stations that has been partly evaporated, concentrating the salt content
effluent being discharged.
What did the extinction of the dinosaurs lead to
Answer:
A big meteorite crashed into Earth, changing the climatic conditions so dramatically that dinosaurs could not survive. Ash and gas spewing from volcanoes suffocated many of the dinosaurs. Diseases wiped out entire populations of dinosaurs. Food chain imbalances lead to the starvation of the dinosaurs.
