Answer:
b. silica
Explanation:
The majority of the volcanoes that form at subduction zones, or convergent plate boundaries, are stratovolcanoes. These volcanoes are also called composite volcanoes. The stratovolcanoes are known to have high to intermediate silica content of the lava they release. The eruptions tend to be periodic, and they are explosive and effusive in general, though there are exceptions. The fact that the lava is high to intermediate in silica content means that the lava is medium to highly viscous. Because of this, the lava tends to trap the gases in it, and as it reaches the surface and the temperature and pressure sharply change, the gases explode, resulting in eruptions that have lot of explosions and propelling of pyroclastic material.
Answer:
Explanation:
Un geógrafo es un científico e investigador cuyo campo de estudio es la Geografía, el estudio de la superficie terrestre, tanto en su composición física como en las actividades e interrelaciones humanas que ocurren en ella. Estudian la superficie de la Tierra (geosfera) de acuerdo con sus estructuras espaciales, los procesos que tienen lugar y sus funciones (interacciones entre los geofactores). Trabajan entre las ciencias naturales, las ciencias sociales y las humanidades y se engloban en el grupo de profesiones que manejan información espacial.
Los geógrafos son generalistas debido a la amplitud de su campo de estudio y ser la Geografía una ciencia transversal, lo que le facilita integrarse con otros profesionales en equipos pluridisciplinares. Su forma de trabajar es a la vez analítica y normativa: los geógrafos empleados como planificadores se guían por la comprensión moderna de la planificación y brindan soluciones para los problemas entre los humanos y el medio ambiente.
They young populations are challenging and expensive for a country to care for because they require more healthcare, immunization, and checks-up , Especially for children. Not only that, they also still haven't be able to contribute to the country's economic growth
Answer:
A) Unlike other maps, topographic maps indicate man-made and natural landforms.
Explanation:
B is wrong because the locations of countries and cities are found in many maps and are considered very common.
C is wrong because like B, compass roses are very common on maps.
D is wrong because like B, boundary lines are very common on maps.
