Yes, repeatedly.
Fossils tell how Earth's landforms, climate, and ecosystems have changed over time. They provide valuable clues about the past by preserving evidence of ancient organisms and environments.
They have been slowly declining over time because they decay, eventually becoming stable isotopes of other elements.
Yes. Plant pollen tells us what kind of plants were growing there at that particular time. The kinds of plants then give us an indication of what the climate was then. So we can see if the climate has changed over time.
Yes, Alfred Wegener believed that Earth's climate changed over geological time. He proposed that continental drift could lead to significant climatic shifts as landmasses moved to different latitudes, affecting temperature and precipitation patterns. His theories suggested that regions now experiencing temperate climates may have once been located in polar regions, further indicating that Earth's climate has undergone substantial changes throughout its history.
The Earth's surface has changed significantly over time due to processes such as plate tectonics, erosion, and volcanic activity. Continents have shifted positions, mountains have formed and eroded, and oceans have expanded and contracted. These changes have been ongoing for billions of years and continue to shape the Earth's surface today.

how big they are
Ice cores contain valuable information such as air bubbles and isotopic composition that can be used to reconstruct past climate conditions like temperature and atmospheric composition. By analyzing the layers of ice cores, scientists can track changes in these parameters over time and gain insights into how Earth's climate has evolved.

Fossils serve as evidence of changes in organisms over time and reveal major changes in the Earth's surface and climate. By studying the types of fossils found in different rock layers, scientists can understand how life has evolved and how the environment has changed over millions of years. This field of study is known as paleontology.
False. The conditions of Earth's atmosphere at a particular time and place are referred to as weather, not climate. Climate describes the average weather conditions over a longer period of time in a specific region.
how the anemometer changed over time
The continents have moved, Volcanoes and mountains have made hige changes in the earths suface too.

The laws of physics have not changed over time. Our understanding of them has changed over time.
Many elements have naturally occurring isotopes, varieties of the element that have different numbers of neutrons in the nucleus.
