Earth and evolution
Across
- 5. similarities- similar way to get food
- 6. long cylinder of glacial ice recovered by drilling through glaciers in Greenland, Antarctica, and high mountains around the world
- 9. The entire set of genes in an organism.
- 10. Theory- a theory about the continent change based on tectonic plates
- 11. the determination of the age of an object with reference to a specific time scale, such as a fixed calendar or in years before present (BP), based on measurable physical or chemical qualities or associations with written records
- 13. change in environment
- 14. the science or technique of classification.
- 19. cave men
- 23. The comparative study of animal structure with regard to homologous organs or parts.
- 28. the time set of changes made over time
- 29. not living
Down
- 1. where all fossils are found
- 2. going out with family member
- 3. broke down organisms
- 4. the process by which forms of life having traits that better enable them to adapt to specific environmental pressures, as predators, changes in climate, or competition for food or mates, will tend to survive and reproduce in greater numbers than others of their kind, thus ensuring the-perpetuation of those favorable traits in succeeding generations.
- 7. - Analogous structures pertain to the various structures in different species having the same appearance, structure or function but have evolved separately, but do not share common ancestor .
- 8. the variety of genetics
- 10. The physical appearance or biochemical characteristic of an organism as a result of the interaction of its genotype and the environment.
- 12. theory's about the worlds formation
- 15. change in biome
- 16. rocks from lava
- 17. differents in biomes
- 18. plates that connects continents
- 20. Geology. a basic law of geochronology,stating that in any undisturbed sequence of rocks deposited in layers, the youngest layeris on top and the oldest on bottom, each layer being younger than the one beneath itand older than the one above it.
- 21. Any method of determining the age of earthmaterials or objects of organic origin basedon measurement of either short-livedradioactive elements or the amount of along-lived radioactive element plus its decayproduct.
- 22. - Geology, Mining. a break in the continuity ofa body of rock or of a vein, with dislocationalong the plane of the fracture (fault plane)
- 24. black ashy rock from lava
- 25. getting ready for environment
- 26. a rock from magma
- 27. inheriting traits
- 28. changing feature
