Answer:
Option (2)
Explanation:
Strato-volcanoes are the steep, conical shaped, formed by the alternative beds of ash and lava. The magma in this type of volcano contains high silica content and are comprised of bubbles. When the gases are released from these bubbles, then a greater force is exerted from the bottom towards the surface. Due to this, they are very explosive and ejects a huge amount of materials during eruption. For example, Mount St. Helens
.
Cinder cones are the simplest volcanoes with steep sides. They are made of the materials and semi solidified lava that are ejected from the vents of the volcano. Eruptions are often explosive due to the force exerted by the gas and the molten lava and are accumulated near the vent. For example, Paricutin.
<u>These two types of volcanoes are similar in terms of its eruption that is violent and explosive in nature. In addition to that, they both have steep sides.
</u>
Hence, the correct answer is option (2).
Answer:
C. Can be replenished by nature in a short period of time
Explanation:
Renewable, as a word, means that it is able to be replaced again. Renewable energy is energy that is able to be replaced quickly, and will never run out. Solar, biomass, geothermal, wind, and hydropower energy all can be reproduced again without the risk of running out, unlike fossil fuels.
Hope this helps!

You can't really expect to find water stored as a gas, as it cools to a liquid at room temperature. You could easily find evaporated water on a stovetop by boiling water, though.
