Geography Year 11 Unit 2 practice quiz

Facts about Earthquakes: Within the earth, there is tremendous heat as much as 1500 degrees fahrenheit. Heat rises and tries to escape between and through the plates. Consequently, the plates may be displaced and/or ruptured.

An earthquake can:

Many earthquakes take place on ocean bottoms.

Describe how tectonic plates work.

What does the term "Polar Dinosaurs in Australia" refer to?

A divergent plate boundary is when two plate boundaries move towards each other.

A convergent plate boundary is when the tectonic plates move towards each other.

A transform plate boundary is when two plate boundaries:

A volcano belt is where:

100% of volcanic eruptions occur in the northern hemisphere.

Describe the term "pyroclastic surge"[blank_start],[blank_end] and what can it do it do to humans[blank_start]?[blank_end]

The kind of Eruption that took place at Mount Vesuvius was a [blank_start]____[blank_end] eruption, one of the most violent forces of nature.

[blank_start]______[blank_end] igneous rocks are formed when a volcano erupts and [blank_start]_____,[blank_end] or [blank_start]____[blank_end], flows over the surface.

[blank_start]_____[blank_end] igneous rocks are formed when molten rock [blank_start]____[blank_end] deep within the lithosphere.

You can account for the differences in appearance of rocks such as obsidian, basalt and tuff by knowing that basalt often has a crystalline structure and are intrusive, obsidian resembles black glass, and tuff is the result of volcanic ash which is cemented together.

Intrusive features eventually end up on the surface as [blank_start]_____[blank_end] gradually wears down the rock above it.

Sediment is formed:

[blank_start]___[blank_end] occurs when new layers of sediment are deposited on top of older layers and the weight squeezes out any spaces between particles that make up the lower layers, flattening the particles and causing them to interlock. [blank_start]______[blank_end] occurs when minerals, dissolved in water, filter through the sediment and act as cement grains together to form sedimentary rock.

Metamorphic rocks are formed through enormous [blank_start]___[blank_end] and temperatures reaching over 300 degrees celsius.

There are more metamorphic rocks than any other kinds of rock since they are formed in low pressure.

Mineral deposits are concentrated in geological structures through ___ and ___.

An element (a geologic building block) can be broken down into multiple substances.

Minerals are inorganic compounds consisting of one or more elements found in the lithosphere. It must be: 1) A [blank_start]____[blank_end] solid. (Atoms are arranged consistently). 2) Occur [blank_start]___[blank_end]. 3) Have a specific [blank_start]___[blank_end] composition.

3 types of crust include [blank_start]__[blank_end], [blank_start]__[blank_end], and [blank_start]__[blank_end].

Igneous rock forms in what?

Two types of Igneous rock. [blank_start]___[blank_end], which forms in lava and has very fine grains. [blank_start]____[blank_end], which forms in magma and has coarse grains.

Sedimentary rock consists of sediment and originates from pre-existing rock.

[blank_start]____[blank_end] is when the rock particles are cemented together and crystallized from tremendous heat and pressure.

Sedimentary rocks are always formed into vertical layers.

Metamorphic rock undergo a change in shape AND mineral composition, changing a it's still solid.

What zones have the worst earthquake tremors, and how deep can they get?

Earthquakes are measured with (check all that apply):

Body waves travel away from quake's focus. What are S, P, Rayleigh waves, and Love waves?

Tsunamis are always a direct result of hurricanes.
