|
Term
|
Definition
| idal flats are intertidal, non-vegetated, soft sediment habitats, found between mean high-water and mean low-water spring tide datums |
|
|
Term
|
Definition
| the solar tide has an additive effect on the lunar tide, creating extra-high high tides, and very low, low tides — both commonly called spring tides |
|
|
Term
|
Definition
| the solar tide partially cancels out the lunar tide and produces moderate tides known as neap tide |
|
|
Term
| How does the ocean influence climate? |
|
Definition
| ocean circulates warm and cool water, disruption due to melting sea ice and glacier could slow or stop...could lead to cooling of the northern hemisphere |
|
|
Term
| What is the greenhouse effect? |
|
Definition
| Earths atmosphere traps heat/ gas Co2 and methane, prevents it from escaping |
