Earth Sciences & Geology - October 2007

okay mantles... so what i wanna know is weither or not inner core and outer core are the same thing. I know that to some ppl that this is a really stupid question but i need to know this.... i can't find the answer anywhere on the internet so it would be great help if u guys could explain it to me.Oh and definitions would be a great help... links are apperciated.

can you guys go to google earth and type (Venice, Italy) and awnser this question.
If global warming is a real problem, as many scientists and world leaders state, what appears to be Venice’s problem based on what you see in the map? AND assuming that this “problem” is inevitable, use what you see in the map and describe something that the Italian government can do to avoid or minimize the effects of this “problem

THANKS>>>

in a freshmen science class we've been having trouble with this question. if anyone could give us a breif detailed explanation that'd be awesome, thanks!

This film is only on 2 sides and I can see there are spots where it is clear. I'm tempted to scrape it off but don't want to scratch the crystal.

18. Match the geologic features with the type of plate boundaries they are associated with.
Convergent plate boundaries
Divergent plate boundaries
Transform plate boundaries

Andesitic volcanoes
Continental collisions
Deep-focus earthquakes
Deep-sea trenches
Island arcs
Long linear scarps
Mid-ocean ridges
Normal faults
Reverse faults
Rift valleys
Strike-slip faults
Subduction zones

19.Match each mountain/island system with the kind of convergent plate boundary that formed it (if any).

Continental crust colliding with continental crust
Continental crust colliding with oceanic crust
Not a case of plate convergence

Aleutian Islands
Alps
Andes Mountains land and ocean crust collide?
Appalachian Mountains
Cascade Mountains land and ocean crust collide?
Hawaiian Islands
Himalayan Mountains
Mariana Islands
Ural Mountains

6. How did non-believers in Wegener's theory explain plant and animal distributions in the southern hemisphere?
Dispersal by winds
Dispersal via now-sunken land bridges

7. What finally convinced geologists that the continents did move?
Dinosaur distributions
Lystrosaurus in Antarctica
Mantle convection
Paleomagnetism

9. When a ship passes over seafloor that has a 'reverse' magnetic polarization, how does this effect the magnetic field reading?

The magnetic field is directed east.
The magnetic field is directed south.
The magnetic field is directed west.
The strength of the magnetic field is slightly stronger than usual.
The strength of the magnetic field is slightly weaker than usual.

14. Which sea is an example of rifting forming an incipient ocean?
Baltic Sea
Bering Sea
Black Sea
English Channel
Red Sea

16. How does plate tectonic theory explain the Ural Mountains separating Europe and Asia?
Ancient collision and suturing of Europe and Asia
Eurasia is moving over a hot spot in the mantle
Incipient rifting apart of Europe and Asia
Intraplate orogenesis in Eurasia
The Urals are the one mountain chain that was better explained by older theories.

1. What is the concept that adding or removing a weight from the earth's crust causes it to depress or rebound?
Isostasy
Plate tectonics
Rifting

2. What name did Wegener give to his theory of horizontal crustal movements?
Continental drift
Isostasy
Plate tectonics
Rifting
Seafloor spreading

4. What type(s) of evidence did Wegener use to support his theory?
Distributions of fossil plants and animals
Distributions of modern plants and animals
Geographic fit of the continents and features thereon
Paleoclimatic oddities such as glacial till, coral reefs, and coal
All of the above

5. Why was Wegener's theory rejected by geophysicists of the 1920's?
Lack of a mechanism for continents to plough through oceanic crust
The concentration of continents in the northern hemisphere
The presence of a continent directly over the south pole

Man is the great inventor. If we use up all the oil, we will simply invent new technology to thrive and survive. Look at how we've responded with the green movement. I have faith in humankind!

300 millions years ago ,the continents were joined together. Now they are separated and Alfred Wegener proved that they were joined.

The scinentist disagreed y is that?
