The tide in the picture is a (a) .
During this tide, the high/low tides will be (b) than usual.
Determine the tide that each region would be experiencing:
High tide
Low tide
The tide in this picture is a (a) .
During this tide, the high/low tides will be (b) than usual.
Neap tides will occur at (a) and (b) .
Spring tides occur (a) .
This is a (a)
Tides are caused by the graviational pull of the (a) .
The Earth experiences the rise and fall of ocean water, which is called (a) , because of the pull of gravity of the (b) .
The diagram shows the relative positions of the sun, moon, and Earth during one revolution of the moon around the Earth. Choose the positions of the moon that will result in neap tides. Select TWO that apply.
Figure (a) which mean “ (b) ” because the water during high tide rises very high.
Which model shows a SPRING Tide?
The moon would be place in position (a) and (b) for a Spring (c)
Season
object's complete turn around its own axis.
an invisible line around which an object spins.
period of the year distinguished by special climatic conditions.
Why does the area around the equator stay the same temperature year-round and consequently no seasons?
It tilts towards the sun in summer, so has longer hours of daylight.
It receives the same amount of direct sunlight year-round
Its days are more than 18 hours long year-round
The equator rotates slower than the poles
True or False: Daylight hours and temperatures increase from summer to winter.
True
False
A student goes to Ecuador, located along the equator, during winter break. The student notices that even though it is winter, it is still very warm. Why is it very warm in Ecuador even though it is winter?
Ecuador is along the equator, which always receives indirect sunlight and experiences the least seasonal change.
Ecuador is along the equator, which always receives direct sunlight and experiences the least seasonal change.
