Answer:

There are mainly 4 types of volcanoes.

Explanation:

1. Cinder cones: They are a bowl-shaped crater,  build from particle or blobs of congealed lava that is ejected from a single gas vent, as the air is broken into small fragments that are solidified and falls as cinders.

2. Composite volcanoes: stratovolcano or composite cone are those that form a steep-sided, symmetrical cone of large dimensions built around by lavas. Some examples are Mount Shasta in California, Mount Hood in Oregon.

3. Lava domes: There internal structure is defined by bulbous masses of lava, that are too vicious.

4. Shield volcanoes: These are built entirely by fluid lava, and flow p[ours in all directions.

A volcano can change its surrounding weather patterns but not the climate of a place as a climatic zone is composed of stable and static atmosphere like that of poles, tropics, and temperate lands, etc.  

Not all volcanic eruptions can be predicted successfully as they are also triggered by an earthquake and the active or dominant type of volcano can be identified based on its previous eruption patterns.

Describe the formation of a volcano.
pentagon [3]

Answer:

Volcanoes are formed when magma from within the Earth's upper mantle works its way to the surface. At the surface, it erupts to form lava flows and ash deposits. Over time as the volcano continues to erupt, it will get bigger and bigger.

9. Which forces do scientists believe are responsible for the movement of Earth's
SIZIF [17.4K]
The main reason why the tectonic plates move is the conversational currents. There is magma between the upper mantle and the asthenosphere that heats up at the upper mantle. The weight is so small that the magma rises with the help of these conversational currents. When the magma has ascended towards the asthenosphere, it has nowhere to go so the magma lies along the asthenosphere. There the magma cools down again because the asthenosphere is colder than the upper mantle, which makes the magma heavier and goes back down to the upper mantle, where the magma heats up again and everything starts all over again and so it goes on over and over again. Scientists have concluded that the earth's gravity causes two other processes that also cause the tectonic plates to move.

Ridge push - in the spreading zones, the sides of the tiles are raised and slide to the side as in a slide.
Slab pull - when a plate is pulled down by gravity in a subduction zone like an anchor.

Water collects in small cracks in a rock, then freezes. The expansion of the water while frozen causes the rock to crack further
iragen [17]

This specific process is called frost weathering or cryofracturing. It is a situation when Water collects in small cracks in a rock, then freezes. and caused the rock to crack and break off in pieces.

<h3>What is frost weathering?</h3>

Frost weathering is physical weathering that involves freezing and thawing of waters in an area with extremely cold weather. When water freezes its size expands and damages the area.

Its best example is when water collects in small in a rock then freezes. The expansion of the water while frozen causes the rock to break into pieces.

Therefore the Forst weathering is from of physical weathering.
