Justify why the concept of development remains highly contested And explain an appropriate definition of Development for policy dialogue in your district
Answer:
The reason why the concept is contested is because it is difficult to establish objective parameters on which to base the measure of how developed a country is or not.
Explanation:
To measure development, many indicators have been proposed, like GDP, GDP Per Capita, Poverty Rate, Unemployment Rate, Energy use, etc. However, economists and social scientists do not agree on which of these indicators are more important than others, or on which should be used.
The most appropriate definition for development would be: 'the process in which a community, a district, a city, or a country improves the economic and social well-being of its inhabitants or members".

Reflection:
Direction: Write a short inspired reflective essay about the advantages and disadvantages of tropical cyclones to our environment and our daily living in the space provided .[ three (3) to five (5) sentences ONLY]
Answer:
Even though we may see more clearly the disadvantages that tropical cyclones cause, they are also beneficial for our planet and life.
Tropical cyclones provide water to areas that will not have it without them. The water, which comes from the cyclones' rains, helps in agricultural activities. Also, tropical cyclones regulate the high temperatures in the Equator moving large masses of warm air from the Equator to the North and South pole, reducing the temperature in the Equator, which has high temperatures due to the incidence of the sun's rays on it.
On the other hand, tropical cyclones can destroy houses, cities, kill people, damage a country's economy, or affect people's life. Besides, they can affect the valance of an ecosystem since they destroy the habitat of many animals, and they are responsible for the death of some.
Explanation:
In this essay, the mentioned advantages are the rain that cyclones brings to areas where it is necessary for the economy in agricultural activities and the effect that tropical cyclones have in the Equator regarding temperatures in this area.
The mentioned disadvantages are the damages that they leave behind and the lives they take with them, which affects our life, environment, and economy.
Tropical cyclones is responsible for rainfall as well as destroy vegetation.
Tropical cyclones are extremely important for rainfall production, and thus, can also be efficient for drought busters. In areas of drought, such as parts of the Southeast and Northeast, rain from a tropical cyclone can be beneficial for both vegetation and animals.
While on the other hand, Tropical cyclones destroy forest canopy as well as change the landscape near coastal regions by reshaping sand dunes that leads to extensive erosion along the coast. On inland, heavy rainfall can lead to landslides in mountainous areas so we can conclude that tropical cyclones is responsible for rainfall as well as destroy vegetation.

When sediments are first weathered from their source rock, they are ___________________________ and ___________________________ sorted. As they travel, they impact against each other or against bedrock, a process that ___________________________ off sharp corners and wears down the sediment size. Sediments that are finer, ___________________________ rounded, and ___________________________ sorted indicate that the sediments have traveled a long way from the source.
Answer:
Eroded; poorly; abrasion; coarse-grained; well.
Explanation:
A rock cycle can be defined as a concept used to describe the continuous process that leads to a rock's creation, formation, transformation from one form to another, destruction and reformation over a specific period of time. The natural phenomenons that influences the rock cycle are weathering, plate tectonic activity, erosion, etc.
Basically, the three (3) main types of rocks are; igneous rock, sedimentary rock and metamorphic rock.
Weathering can be defined as the physical and chemical breakdown of rock into smaller pieces called sediment. Weathering can be classified into two categories namely;
I. Physical weathering : it is the process of breaking rocks into pieces without affecting its chemical composition e.g temperature, abrasion and frost action.
II. Chemical weathering : it is the process of breaking rocks into pieces by chemical action which leads to changes in its chemical composition e.g carbonation, hydration, plant acid and oxidation.
When sediments are first weathered from their source rock, they are eroded and poorly sorted. As they travel, they impact against each other or against bedrock, a process that abrasion off sharp corners and wears down the sediment size. Sediments that are finer, coarse-grained, rounded, and well sorted indicate that the sediments have traveled a long way from the source.

Mercury in a box have density is 30000kg/m^3 height is 20 dm. Determine the pressure of Mercury .
Answer:The pressure of Mercury = 588,600Pa
Explanation:
The pressure of Mercury is given as
p=h x ρ x g
Where h =height= 20 dm
changing to meters
10 decimeters (dm) =1 meter
20dm =2 meter, 2m
ρ is the density =30000-kg/m³
g , gravity = 9.81-m/s²
Pressure = 2.0m x 30000-kg/m³ x 9.81-m/s²
588,600 kg.m/ s²/m² =588,600 N/m²
The pressure of Mercury=588,600Pa

5-por que o indicador de renda per capita sozinho pode "mascarar" a real situação socioeconômica de um pais
Answer and Explanation:
Porque o percentual de renda per capita pode generalizar a situação econômica de todos os habitantes do país, mostrando valores maiores do que o que é real. Isso porque o percentual de renda per capita é obtido com a divisão da situação econômica nacional com o numero de habitantes. Isso gera um valor muito generalizado e acaba mascarando a situação das áreas e dos habitantes mais pobres do país que pode ser a maioria da população.

Explanation:
Temperature can be defined as a measure of the degree of coldness or hotness of a physical object. It is measured with a thermometer and its units are Celsius (°C), Kelvin (K) and Fahrenheit (°F).
Radiation is simply the transmission or emission of energy in the form of particles or electromagnetic waves through a vacuum, material medium or space.
