The Paleozoic era, from 541 to 252 million years ago, saw the rise of the first fish and the first land plants. It was also a time of great diversification, as new groups of animals evolved and formed complex ecosystems.
A sequence is a pattern of observable phenomena that occur in a predictable order. In sequence stratigraphy, these are layers of sediment deposited over time in a predictable manner due to the effects of environmental changes that affect tectonics, sediment supply, and sea level.
In this lesson you will learn about how the movements of the Earth, Moon, and Sun affect different phenomena on Earth, including day and night, the seasons, tides, and phases of the Moon. Lesson Objectives
They explain how the relative positions of Earth, the sun and moon affect phenomena on Earth. They analyse how the sustainable use of resources depends on the way they are formed and cycle through Earth systems.
Hace 5 días · Earth's tilted axis causes the seasons. Throughout the year, different parts of Earth receive the Sun's most direct rays. So, when the North Pole tilts toward the Sun, it's summer in the Northern Hemisphere. And when the South Pole tilts toward the Sun, it's winter in the Northern Hemisphere.

Understanding solid Earth phenomena, including the formation and evolution of tectonic plate boundaries, requires an insight into the physical conditions (e.g., stress) of the geological settings at which these phenomena occur.
