100

The balance of weights  of rock, water, and ice with the upward force of the mantle.

What is isostasy.

100

The this settles it forms a flat or nearly flat layers.

What is sediment. 

100

This is a depositional mountain landform built from solidified magma from deep in the earth.

What is a volcano. 

100

The melted snow caused a volcanic mudslide

What is a lahar.

100

This volcano belt lies above the collision boundary of the African, Indo Australian, and southern Eurasian plates.

What is the Alpine-Himalayan

200

Tectonic processes that geologists believe resulted in the making of mountains fall

What is orogeny.

200

These mountains that form from folded rock strata are called?

What are fold mountains.

200

This refers to anything having to do with molten earth materials, including the rocks and minerals that come from them.

What is igneous. 

200

What are vents in the ground where steam and other

gases from volcanic activity escape.

What are Fumaroles

200

This volcano belt surrounds most of the Pacific Ocean.

What is the Circum-Pacific

300

“a natural elevation of the earth’s surface rising more or less abruptly to a summit.”

What is a mountain.

300

is a trough or downward fold of rock strata formed just like an anticline.

What is a syncline.

300

As the lava breaks through the side of the main cone or beside it, the lava creates smaller cones called

What are parasitic vents.

300

When gas­ laden lava explodes in the volcano’s vent, the fine mist of solid lava falls as

What is ash.

300

Scientists think that there are about #### active and dormant volcanoes on land.

What is 1500.

400

the difference in height between the highest and lowest elevations of the terrain is known as 

What is relief.

400

broad regions of relatively undisturbed sedimentary deposits lifted by some tectonic process.

What are plateaus

400

 the form a huge crater­like depression called

What is a caldera.

400

This is a layer of loose pyroclastic materials and ash covering the ground.

What is Tephra. 

400

Thick layers of igneous rocks cover many places in the world, including the ocean floor.

What are flood basalts

500

This is the largest mountain range on the earth.

What is the Mid-Ocean Ridge.

500

These are mountains that were carved out by extensive erosion, usually from a plateau.

What are Erosional Mountains.

500

Sometimes a volcano erupts a mixture of hot solid particles suspended in water vapor or other gases. This hot mixture, is so dense that it flows down the volcano’s slope instead of rising into the air. At night, the entire flow glows a dull red. 

What is pryoclastic flow.

500

When volcanoes erupt, they can also emit ash, cinders, bombs, and sometimes large chunks of rock.

What is called pyroclastic material.

500

Flood geologists agree that nearly all volcano landforms probably came into existence during

The Genesis Flood or shortly after.
