Does the lava that forms shield volcanoes probably have a lot of silica or water in it?

No. Shield volcanoes form from basaltic lava with a low silica content and a low water content.

What forms from lava that is higher in water and silica content than lava that forms shield volcanoes?
Cinder-Cone Volcanoes and Composite Volcanoes
What kind of lava forms shield volcanoes?
Shield volcanoes are fed by basaltic magma.
What kind of volcano form from lava that is higher in water and silica content than lava that forms shield volcanoes?
cinder cone
How steep are shield volcanoes?
Shield volcanoes almost always emit very fluid or runny lava that spreads over a wide distance, so these volcanoes are not steep.Yes and no, it depends where and how the volcano forms, when it discombobulates, and so on.
What type of material makes up volcanoes with broad sloping sides?
Basalt lava forms shield volcanoes which are known for their broadly sloped flanks. This is because there is a low amount of Silica in the volcanic material allowing the magma to flow very freely giving the broad flanks as lava flows out.

Are hawaiian islands spatter cones?
No, they're shield volcanoes. The lava in spatter cones is highly viscous whereas the lava that forms shield volcanoes (that you can see flowing in Hawaii) has a very low viscosity. Shield volcanoes are low profile, broad lumps; these are the Hawaiian islands.
Does a shield volcano have runny lava?
In volcanoes that have lower amounts of volcanic gases in the magma. A good example is the volcanoes in the Hawaiian islands. Volcanoes with more gases in the magma tend to erupt explosively (Mt. St. Helens, Vesuvius) and have a thicker, slower moving lava.
What are gentle sided and steep sided volcanoes?
gently sloping volcanoes are called shield volcanoes and they are formed from many eruptions of lava that is relatively low in silica, so it spreads out in many thin layers and creates the gently sloping sides of a shield volcano.
What are specific characteristics about a shield volcano?
The name derives from a translation of "Skjaldbreiður", an Icelandic shield volcano whose name means "broad shield", from its resemblance to a warrior's shield. Shield volcanoes are formed by lava flows of low viscosity - lava that flows easily. Consequently, a volcanic mountain having a broad profile is built up over time by flow after flow of relatively fluid basaltic lava issuing from vents or fissures on the surface of the volcano. Many of the largest volcanoes on Earth are shield volcanoes. The largest in terms of area covered is Mauna Loa of Hawai'i; the tallest measured from its base under the ocean, however, is Mauna Kea of Hawai'i. All the volcanoes in the Hawaiian Islands are shield volcanoes.
How do you escape a eruption of Mauna Loa?
Mauna Loa, along with all the other volcanoes in the Hawaiian archipelago are Shield volcanoes. The lava is usually slow moving and takes days to move any noticeable distance. Shield volcanoes are different from stratovolcano. Stratovolcanoes explode and create pyroclastic flows that travel hundreds of miles and hour. Shield volcanoes are characterized by low-explosive fountaining that forms cinder cones and spatter cones at the vent.
A is a large circular depression that forms when a volcanic mountaintop collapses into the magma?
It is important to know the terms of the landforms on the Earth. A shield volcano is a wide gently sloping mountain made of a hardened layers of low silica lava.
