Why does ice become less dense than water?

Answers

Answer 1
Ice actually has a very different structure than liquid water, in that the molecules align themselves in a regular lattice rather than more randomly as in the liquid form. It happens that the lattice arrangement allows water molecules to be more spread out than in a liquid, and, thus, ice is less dense than water.

What is one advantage of urbanization?

Answers

Answer:

Advantages of Urbanization

Urban residents in many parts of the world tend to live longer than do rural residents, and have lower infant mortality and fertility rates. Cities provide better access to medical care, family planning, education, and social services. Recycling is more economically feasible.

Ventajas de la urbanización:

Crecimiento sostenido. El crecimiento de las ciudades va acompañado de una mayor demanda de servicios básicos y de bienes de consumo, lo cual genera un mercado mayor a satisfacer.

Concentración poblacional. Las ciudades son ámbitos más controlables por los Estados y con mayor facilidad de cobertura de redes de servicio o de distribución, dado que la población se concentra en algunos kilómetros a la redonda.

Complejización laboral. El mercado de empleo en la ciudad es mucho más diverso y variado que en las zonas rurales, permitiendo así el desarrollo y complejización de las actividades industriales, comerciales y de servicios.

Researchers are using various methods to make observations and collect data about the feeding habits of gorillas in the wild. Which method would be classified as direct observation?
A) Counting and classifying the debris in the area where the gorillas live.
B) Observing the gorillas from a protected location and recording what they eat.
C) Surveying the natives in the area about the diet of the local gorilla population.
