earth and space

3. An artificial body placed in orbit around the earth to collect environmental data from space.
4. A process where deep, cold, nutrient-rich water rises toward the surface to replace warmer water.
11. The blanket of gases surrounding Earth that traps heat and drives weather systems.
12. A spatial scale used to examine objects or structures too small to be seen by the naked eye.
15. The imaginary baseline dividing Earth into hemispheres, receiving the most direct solar radiation.
17. All the waters on the Earth's surface, such as lakes, clouds, and vast oceans.
18. A deviation from the common rule or long-term average, like unusual sea surface temperatures.
19. A continuous, directed movement of ocean water generated by forces like wind and density.

1. The solid, rocky part of the Earth, extending from the crust down to the core.
2. A broad spatial scale relating to large-scale regional or global land and climate features.Data Facts, statistics, or measurements collected by oceanographers together for analysis or reference.
5. The close, mutually beneficial relationship between coral polyps and microscopic zooxanthellae algae.
6. A steep temperature gradient in a body of water, separating the warm upper layer from cold deep water.
7. The geological process in which earthen materials are worn away and transported by natural forces.
8. The concentration of dissolved mineral salts present in a given volume of ocean water.
9. The arrangement of the natural and artificial physical features of an area on a map.
10. The geological process where sediments, soil, and rocks are added to a landform or landmass.
13. Solid particulate matter that settles to the bottom of a liquid, often formed by weathering.
14. The global ecological system integrating all living beings, including coral reef habitats.
16. A system loop where the output or response self-amplifies or dampens the original process.
