Answer:
Explosive and effusive eruption types resulting from the activity of magma composition, temperature, water content and volatile content.
Explanation:
Magma Silica content composition being above 60% will result in violent eruption. High temperature will result in low viscosity and low temperature in high viscosity. Explosive eruptions are propelled by magma and motivated by gaseous activity. Effusive is characterized with lava outflow without explosive activity. Examples of this effusive eruptions are those of the Hawaiian eruptions. Plinian eruptions are known to be explosive, violent and dangerous.

True
Explanation:
The Canadian government contracted the Canadian Pacific Railway in 1880. It was constructed over the next 5 years to connect eastern Canada with British Columbia.
La revolución industrial de Alemania se produjo en el siglo XIX, luego del proceso de industrialización que ya venía desarrollando Inglaterra. Esta última facilitó la revolución que Alemania viviría ya que invirtió capitales, maquinaria y debió abastecerse de mano de obra especializada, y se radicó con más fuerzas ya que las regiones de Alemania contaban con variados recursos naturales. Este acontecimiento trajo consecuencias políticas y por supuesto económicas, las que influyeron de forma importante en todos los aspectos.

Answer:
The active volcanoes are gradually moving away from the oceanic ridge.
Explanation:
- Many oceanic volcanoes occur as long lines of the active end of volcanoes as here in the mid-oceanic ridges the plate is pushed far away from the ridge surface of the earth as these tend to move out in the direction of the movement of the plates.
- Thus the volcanoes are generally found near the active zones or regions of the tectonic plate and associated with the earthquakes occurring on the fault line or shear lines of the plates.
- Spreading of the ridges as a result of the seafloor spreading takes place and the mantel and plates from below are the driving forces that make the volcanoes and convection current that rises through the mantle pushes or spread the volcanoes to the sides like seen in the ring of fire.
Answer: The Earth is a closed system for matter
That is a list of all basic elemental materials on our planet. Because of gravity, matter (comprising all solids, liquids and gases) does not leave the system.
