Most Regents exams consist of a single three-hour testing period. The exception is the Earth Science exam, which consists of a 41-minute (approximate) laboratory component, known as the Earth Science lab practical, given around two weeks prior to the three-hour exam. The Regents exams are administered in January, June, and August.
Earth science or geoscience includes all fields of natural science related to the planet Earth. [1] This is a branch of science dealing with the physical, chemical, and biological complex constitutions and synergistic linkages of Earth's four spheres: the biosphere, hydrosphere / cryosphere, atmosphere, and geosphere (or lithosphere). Earth ...
Earth is rounded into an ellipsoid with a circumference of about 40,000 km. It is the densest planet in the Solar System. Of the four rocky planets, it is the largest and most massive. Earth is about eight light-minutes away from the Sun and orbits it, taking a year (about 365.25 days) to complete one revolution.

This is a list of tectonic plates on Earth's surface. Tectonic plates are pieces of Earth's crust and uppermost mantle, together referred to as the lithosphere.
For example, in June 2023, one team of scientists reported evidence that Earth may have formed in just three million years. [11][10] Nonetheless, within the first billion years of the formation of Earth, [12][13][14][15] life appeared in its oceans and began to affect its atmosphere and surface, promoting the proliferation of aerobic as well as ...
The natural history of Earth concerns the development of planet Earth from its formation to the present day. [1][2] Nearly all branches of natural science have contributed to understanding of the main events of Earth's past, characterized by constant geological change and biological evolution.
