Various Earth Science Questions. Help Please!!!?

!) Ion

2) False. Atoms of different atoms contain different number of protons.

3) The Earth's inner core is solid, outer core is liquid.
4) Only some of our knowledge comes from deep-sea drilling. Geologists found information from the excavation of fossil fuels ( oil mines) and digging of natural-occurring metals ( like iron from the ground). Of course, they also used discovered geysers and mud pools, which revealed a lot about the earth's interior. Earthquakes and volcanic eruptions also gave them insight into this aspect. It was also through the examination of lava.

5) False. Scientists discovered that west Africa was actually connected to South America millions of years ago( a single continent), before the ice age. The African Plate separated from the South American Plate through continental drifting. Even at this point, it is still moving further away from the South American Plate.

6) Refer to http://pubs.usgs.gov/gip/fossils/fig15.gif

7) False. seismographs can detect up to several thousands meters, more than 1000 miles.

8) True

9) True. There are several equipments that can be used.

10) True. Basalt can be found near mid-oceanic ridges.

Any help would greatly be appreciated!!!

Questions:

An atom that loses or gains electrons is called?
a.isotope b. proton c. neutrino d. neutron e. ion

True False:
All atoms with the same number of prtons are given the same name.

The Earth's outer core is solid, and the inner core bahaves as a liquid.

Most of our knowledge about the Earth's interior comes from deep-sea drilling.

Measurements indicate that the west coast of Africa and the east coast of South America are getting closer together.


The geologic time scale was originally constructed by scientis without the aid of numerical dates.

Seismographs can only detect earthquakes within 500 miles of the instrument.

Most major earthquakes are followed by smaller tremors, some of which can be destructive to already weakened structures.

There are several reliable methods of short-range earthquake predictions.

Volcanic islands found in the deep ocean basin are generally composed of basaltic rocks.

2 F They share a wide variety of charastics but not the same name.
3 F Earth's ourter core is liquid and inner core is solid.
4 F read why http://pubs.usgs.gov/gip/interior/
5 F they are getting further apart.
6 F The two types of dates used by geologists to interpret Earth history are 1) relative dates, which put events in their proper sequence of formation, and 2) numerical dates, which pinpoint the time in years when an event took place.
