What factors affect the viscosity of lava?

The three factors that influence the viscosity of a lava are temperature, the dissolved gases it contains, and its chemical composition. What are the 3 factors affecting the viscosity of magma? A magma’s viscosity is largely controlled by its temperature, composition, and gas content (see downloadable programs at the bottom of this page). The effect

How do you make a paper mache volcano explode?

Get Ready to Explode The eruption happens as a result of a chemical reaction between two substances—baking soda and vinegar. You’ll need up to a cup of vinegar and two tablespoons of baking soda, though this may change depending on how large your volcano and its crater happen to be. How do you make an

What is the difference between primary and secondary minerals?

The key difference between primary and secondary minerals is that primary minerals are formed from primary igneous rocks whereas secondary minerals are formed from weathering of primary rocks. A mineral is a naturally occurring, inorganic solid substance that has a well-ordered chemical structure. What is a secondary mineral? When rock minerals undergo a transformation process

What are characteristics of sedimentary rocks?

Sedimentary rocks can be formed only where sediments are deposited long enough to become compacted and cemented into hard beds or strata. They are the most common rocks exposed on the Earth’s surface but are only a minor constituent of the entire crust. Their defining characteristic is that they are formed in layers. What are

What was Charles Darwin job on the ship?

In 1831, Charles Darwin received an astounding invitation: to join the HMS Beagle as ship’s naturalist for a trip around the world. The life of Charles Darwin “Charles Darwin was born in England on February 12, 1809. His father wanted him to become a doctor, but the young man was more interested in nature. He

What is fast mass wasting?

Mass wasting is the movement of rock and soil down slope under the influence of gravity. Rock falls, slumps, and debris flows are all examples of mass wasting. Often lubricated by rainfall or agitated by seismic activity, these events may occur very rapidly and move as a flow. What is rapid mass wasting? In rapid

What are the types of divergent boundaries?

There are two types of divergent boundaries, categorized by where they occur: continental rift zones and mid-ocean ridges. What type of boundary is divergent? A divergent boundary occurs when two tectonic plates move away from each other. Along these boundaries, earthquakes are common and magma (molten rock) rises from the Earth’s mantle to the surface,

Which terrestrial planet has the youngest surface?

Why does Earth have the youngest surface of all the terrestrial planets today? the Appalachian Mountains. Why does Earth have the youngest surface of all the terrestrial planets today? It is the largest terrestrial planet so its interior has not cooled too much. It is not so close to the Sun that it has lost

What are three types of convergent boundaries examples?

There are three types of convergent plate boundaries: oceanic-oceanic boundaries, oceanic-continental boundaries, and continental-continental boundaries. Each one is unique because of the density of the plates involved. What are 3 examples of convergent boundaries? Three types of convergent boundaries are recognized: continent‐continent, ocean‐continent, and ocean‐ocean. Continent‐continent convergence results when two continents collide. … Ocean‐continent convergence

Where does compaction and cementation occur?

Rainforests, dry forests, sand dunes, mountain streams, lakes, rivers, oceans, beaches, and deltas are just a few examples of where compaction, and eventually cementation, can occur. What rock is cementation and compaction? sedimentary rock After compaction and cementation the sedimentary sequence has changed into a sedimentary rock. Sedimentary rocks like sandstone, shale and limestone differ
