Not exact matches

To participate, students should be currently enrolled in a high school earth sciences course (or equivalent) or an undergraduate meteorology course (or equivalent) in which students have been taught how seasonal changes in the relationship between the earth and the sun affect hours of daylight, maximum height of the sun in the sky, and the amount of energy a place on earth receives from the sun.
For example, the ice ages during the last several million years — and the warmer periods in between — appear to have been triggered by no more than a different seasonal and latitudinal distribution of the solar energy absorbed by the Earth, not by a change in output from the sun.
The team concluded that the «inversion» of the brightness of Saturn's rings between 2005 and 2008 was caused by the seasonal change in the ring opening angle to the Sun and Earth.
In this study, we undertake another effort towards understanding the role of the Sun in changing or varying the Earth's climate on seasonal to decadal time scalIn this study, we undertake another effort towards understanding the role of the Sun in changing or varying the Earth's climate on seasonal to decadal time scalin changing or varying the Earth's climate on seasonal to decadal time scale.
Though the Earth rotates around the sun in an ellipsis, it's not the planet's changing distance but rather its changing orientation that determines seasonal shift.
Although the primary driver of glacial — interglacial cycles lies in the seasonal and latitudinal distribution of incoming solar energy driven by changes in the geometry of the Earth's orbit around the Sun («orbital forcing»), reconstructions and simulations together show that the full magnitude of glacial — interglacial temperature and ice volume changes can not be explained without accounting for changes in atmospheric CO2 content and the associated climate feedbacks.
The initial changes in temperature during this period are explained by changes in the Earth's orbit around the sun, which affects the amount of seasonal sunlight reaching the Earth's surface.
The impact of tree planting in previously unforested areas can be paradoxical, as it depends both on seasonal changes in surface albedo, eg, from snowfall and sun angle a and shadow area effects.
