D. high and low levels of silica in the different type of lava.

Explanation:

The volcanoes have different types of explosions. Some tend to be highly explosive, some less explosive, some don't have explosions at all, while some have combinations of different eruptions. The reason for this diversity in the eruption types is mostly the composition of the magma, or rather how high is the silica content in it.

Basically, the higher the silica level in the magma the higher the explosiveness, and the lower the silica level the lower the chances of explosiveness. This is the case because the higher amount of silica makes the magma thicker, so the gasses are trapped and they explode, while when the lower silica content makes the magma less thick, so the gasses are not trapped and explosions are lacking.

Mountain building, weathering, and erosion eventually expose the fossil at the surface. Sedimentary rock is the type of rock that is made of hardened sediment.

What are the geographical factors that should be kept in mind by civil engineers in case of designing a multi storey building ~
Lelu [443]

It's crucial for an engineer who is just beginning to design multi-story buildings to go logically through each stage of the design process. Below are six steps that make up this sequence.

Basic guidelines to design a multi-story building

Each stage includes general guidelines to assist the designer in rapidly and effectively coming up with a workable solution for a specific set of limitations. In order for the end result to be both logical and attractive, the designer must also understand some general principles of excellent design.

The stages of a building project are presented.

Defining a project: What it is, why it is being proposed, where it is, etc.

Putting the facts together and creating the brief - Recognizing the location and context.

Designing a scheme involves considering and creating choices and a thorough design of the numerous parts and pieces.

Drawings and specifications for construction information

Construction.

Places on or near the Equator receive about 12 hours of daylight in June. Approximately how many hours of daylight do those same
Natasha2012 [34]

Answer:

B) 12 hours of daylight.

Explanation:

B) 12 hours of daylight.

In near the equator we experience 12 hours of daylight as the equator is situated exactly the halfway in between the two poles. The North pole experiences  long daylight in the months, when the North Pole is tilted towards the Sun and shorter daylight when the pole tilted away from the Sun. The reverse is true for the Southern Poles. But this wouldn't have any effects in daylight on the equator.
