which volcano is this

The white-hot outer core consists of molten (melted )

Weak earthquakes that cause slight vibration of the ground and low rumbling sound

The soil, sediment& rocks within a few ft of the earth's surface warm up during the day and _______ in temp with depth

Volcanoes that have not erupted in recorded history or are unlikely to ever erupt again

Under these conditions, the lava fragments of rock are called...

Volcano that erupts recently or is considered likely to erupt in near future

The largest of theses tephra measure several feet across

Earth's crust is not one huge, unbroken shell of rock, but of several individual ________ that float like raft

The volcano produces a large amount of fluid lava that surge from the volcano's vent like water from a fountain.

when plates are dragged in different directions, colliding or grinding together at the edges - producing mountains

Which volcano is missing

reaching the earth's surface molten rock - which cools and hardens and collects in the mouth of the volcano

Geologists call these vents that emit harmful gases, enriching the soil with their vapors

the point under ground where an earthquake begins is called

Oceans containing underwater mountain ranges where moving plates occur on the sea floor -crust move away from each other

Circulating electric currents in the liquid metal of the outer core generate the

fragments more than 2 1/2 inches across also known as 1 of tephra types

this vent releases the pressure within he magma chamber is called

An earthquake is the place at the ground level that is directly above the focus - often receiving the most damage

earthquakes are caused by moving in difference directions or

the lava erupts from a long rack or fissure instead and may produce a sheetlike fountain of glowing lava

Formed by eruptions composed mostly of tephra or small fragments of solidified lava

if rocks crack, but does not move in anyway as a result is called

The Himalayans is the highest mountain on Earth that lie between which two boundaries

Volcanoes that have lain dormant for a long period of time

Which volcano is this

This volcano produces both cinder and lava, creating a cone that had both characteristic of cinder & shield volcanoes

The forms when large amounts of fluid, runny lava gradually build up a dome-shaped mountain -

Fragments that are smaller than bombs/blocks but larger than volcanic ash

The rocks of the crust are covered by thin layer of soil and a thick layer of sand and mineral fragment called

Which type of erupting volcano erupts every 20 min in Italy and is known as the "Lighthouse of the Mediterranean"

new soil is formed by ________________, a process that causes rocks to gradually break or crumble into smaller pieces

Process that takes place when rock is broken down by water, ice, or windblown sand

The belt, which corresponds to the Circum-Pacific earthquake belt - volcanoes found along plate boundaries

seismologist have devised scales of earthquakes strength in order to compare one earthquake to another is ...

these faults produce most of the world's earthquakes, the regions where they are found are called

the shield volcano has a large depression at its top

The break that appear at the boundary between two moving mases of rock - San Andreas in southwestern California is one

This occurs periodically for days or even months after major earthquakes similar to a tremor

The final trapped gases that blast an opening through the earth's surface

Which layer of the earth makes up the large portion of earths interior?

smallest fragments of tephra resembling dust and fine sand

What is another name of mantle - rocks squeezed to density nearly 2X earth's crust by immense weight of rocks above

natural acids slowly eat into rock and break it apart

Which one is not a major section of interior of the earth?

Lava gushes from a narrow conduit, it may shoot dozens of yards into the air, forming a vertical geyser

the weak spot exists n the earth's crust, where the magma may squeeze its way upward through the crust and form a large

The magma chamber of a volcano is close to the surface, the empty chamber may "cave in " - such as a depression

bubbles of melted rock deep in the earth's hot mantle - lighter than solid rock and squeeze upward
