1The study of fossils is called [blank_start]Palaeontology[blank_end]
- APalaeontology
2To be preserved as a fossil an organism must be
- ABe eaten by scavengers
- BMust decay slowly and be preserved in carbon film, Amber, sediment, peat, or tar
- CA hard fossil preserved in sediment
3Indirect fossils are not part of an organism itself but as preserved remains of things such as imprints of its body (footprints and tracks, fossilised dung and burrows
- AVerdadero
- BFalso
4Fossils can form on igneous and metamorphic rocks
- AVerdadero
- BFalso
5Fossils can be classified as:
- AOriginal, replacement, carbonised, indirect
- BOriginal and replacement
- COriginal, replacement, carbon film and indirect fossils
6A replacement fossil forms when [blank_start]part of a organism[blank_end] is changed into [blank_start]another mineral [blank_end]
- Apart of a organism
- Banother mineral
7Original fossils form when [blank_start]part of the organism[blank_end] is [blank_start]preserved after death[blank_end], but keeping its same chemical composition.
- Apart of the organism
- Bpart of the animal
- Cdead organisms
- Dthe body of an organism
- Epreserved after death
- Fdestroyed after death
- Gfossilised after death
8The fossil record will someday be complete
- AVerdadero
- BFalso
9Relative dating is a technique that [blank_start]compares[blank_end] the age of one [blank_start]fossil of rock[blank_end] with [blank_start]another[blank_end] to determine [blank_start]which is older [blank_end]
- Aanother
- Bwhich is older
- Ccompares
- Dfossil of rock
10Two animal groups that make good index fossils are
- ATrilobites and anthropods
- BInsects and small animals
- CDalamites and Calymene
11Fluorine dating compares the amounts of fluorine in different bones found in the same rock. It depends on how much fluorine join the water surrounding the bone
- AVerdadero
- BFalso
12Humans existed in the Mesozoic period
- AVerdadero
- BFalso
13In the paleozoic period many [blank_start]plants and ferns[blank_end] grew, [blank_start]dinosaurs evolved[blank_end] and the [blank_start]first reptiles[blank_end] appeared
- Aplants and ferns
- Bdinosaurs evolved
- Cfirst reptiles
14Evolution is the theory in which [blank_start]all living things[blank_end] are believed to [blank_start]have evolved from earlier forms[blank_end] in [blank_start]earths history [blank_end]
- Aall living things
- Bhave evolved from earlier forms
- Cearths history
15Natural selection is the process in which [blank_start]organisms[blank_end] that are most [blank_start]well adapted[blank_end] to their environment produce more [blank_start]offspring[blank_end] while [blank_start]the others die out [blank_end]
- Aoffspring
- Bthe others die out
- Corganisms
- Dwell adapted
16Homologous structures are organisms that have similar characteristics and the same basic gene structure
- AVerdadero
- BFalso
17Charles Darwin proposed the theory of evolution in (blank) and he called this process (blank). He concluded that natural selection could only act when there is a variation in the population. Variation is caused by (blank)
- A1853, evolution, differences in genes
- B1858, natural selection, the differences in genes
- C1858, natural selection, differences in appearance and behaviour
18Species are organisms that are [blank_start]similar[blank_end] and [blank_start]capable[blank_end] of exchanging [blank_start]genes[blank_end] and [blank_start]interbreeding [blank_end]
- Asimilar
- Bcapable
- Cgenes
- Dinterbreeding
19Two methods of absolute dating are [blank_start]radioactive dating[blank_end] and [blank_start]tree rings [blank_end]
- Aradioactive dating
- Btree rings
20Radioactive dating is:
- AA method of dating fossils that uses the natural rate of decay of radioactive isotopes. Please google more about isotopes.
- BA method of dating fossils that uses the natural rate of decay or radioactive elements and the breakdown of them. E.g. It's Half life
21Carbon film fossils occur when the [blank_start]dead body[blank_end] partially [blank_start]decays[blank_end] and leaves a [blank_start]thin black deposit[blank_end] of carbon
- Adead body
- Banimal body
- Cspecies
- Ddecays
- Edies
- Fcollapses
- Gthin black deposit
- Hdusty black
- Iblackened deposit
