What happens to the energy that Earth receives?
The energy that Earth receives from sunlight is balanced by an equal amount of energy radiating into space. The energy escapes in the form of thermal infrared radiation: like the energy you feel radiating from a heat lamp. (NASA illustrations by Robert Simmon.)
What would happen to Earth’s temperature if the energy absorbed from the sun?
The earth absorbs about 45% of solar radiation, 29% are emitted back to space. If the energy absorbed by the earth is less than the energy leaving the earth, the earths temperature will decrease. This means that there is less energy coming in compared to the energy lost to space.
What is an example of a neap tide?
An example of neap is weaker tides present in the oceans. Designating a tide which occurs just after the first and third quarters of the moon, when there is least difference between high tide and low tide.
How far ahead can tides be predicted?
They occur approximately 7 days after spring tides. How far ahead can the tide be predicted? As we know the position of the Moon and the Sun very accurately, we are able to compute the tides many years ahead (or into the past).
What is another name for spring tides?

What causes a rare Proxigean spring tide?
The Proxigean Spring Tide is a rare, unusually high tide. This very high tide occurs when the moon is both unusually close to the Earth (at its closest perigee, called the proxigee) and in the New Moon phase (when the Moon is between the Sun and the Earth). The proxigean spring tide occurs at most once every 1.5 years.
What does spring tide mean in geography?
spring tide. A tide in which the difference between high and low tide is the greatest. Spring tides occur when the Moon is either new or full, and the Sun, the Moon, and the Earth are aligned. When this is the case, their collective gravitational pull on the Earth’s water is strengthened.
What does high spring tide mean?
In both cases, the gravitational pull of the sun is ‘added’ to the gravitational pull of the moon on Earth, causing the oceans to bulge a bit more than usual. This means that high tides are higher and low tides are lower than average. These are called ‘spring tides. ‘
How long does high tide stay high?
High tides occur 12 hours and 25 minutes apart. It takes six hours and 12.5 minutes for the water at the shore to go from high to low, or from low to high. Unlike a 24-hour solar day, a lunar day lasts 24 hours and 50 minutes.
