Downwelling is where currents converge, bringing nutrients to the depths of the ocean. In this process, surface water that is rich in nutrients and dissolved oxygen is pushed downwards, primarily due to the influence of wind and the Earth's rotation.

Here is a step-by-step explanation of downwelling:
1. Wind causes surface water to move, creating horizontal currents.2. These currents can converge at certain points, resulting in an accumulation of surface water. 3. As the surface water accumulates, it begins to sink due to the increased pressure and density.

4. The sinking water carries nutrients and dissolved oxygen from the surface down to the depths of the ocean.5. As the nutrient-rich water reaches the deeper layers of the ocean, it provides essential resources for marine life in those areas. 6. The downwelling process helps maintain a balanced distribution of nutrients and oxygen throughout the water column, supporting a diverse range of aquatic ecosystems.

Answer:

Explanation:

The principle of stratigraphy is based on the formation of sedimentary rocks in distinct layers or strata over time. By studying these layers and the fossils they contain, geologists can determine the relative ages of rocks and reconstruct Earth's geological history.

Sedimentary rocks are formed through the process of deposition, where sediments such as sand, mud, and organic matter accumulate over time. As these sediments settle, they form layers, with each layer representing a distinct period of deposition. These layers can vary in thickness, composition, and fossil content.

The principle of stratigraphy relies on the concept of superposition, which states that in undisturbed rock sequences, the younger rocks are found on top of older rocks. This principle forms the basis for establishing the relative ages of different rock layers and the fossils they contain. By studying the characteristics of these layers, such as the type of sediment, the presence of specific fossils, and the composition of the rock itself, geologists can reconstruct the geological history of an area.

Fossils play a crucial role in stratigraphy as they provide evidence of past life forms and help determine the relative age of the rocks in which they are found. Fossils are typically found in specific layers of sedimentary rock, and their presence or absence can indicate the relative age of those layers. By examining the fossil assemblages in different rock layers, scientists can identify and correlate specific periods of time, allowing for the development of a geological timeline.

Overall, the principle of stratigraphy allows geologists to understand the sequence of events that have occurred in Earth's history, including the deposition of sediments, changes in environmental conditions, and the evolution and extinction of organisms. It provides a valuable tool for reconstructing past environments, studying the Earth's geological processes, and unraveling the complex history of our planet.

Answer:

A star that has a greater mass will die out faster.

Explanation:

The reason for this is because the star would need to use up and burn more energy therefore speeding up it's life process.

A star that has a greater mass will die out faster.

A star's life expectancy depends on its mass. Generally, the more massive the star, the faster it burns up its fuel supply, and the shorter its life. The most massive stars can burn out and explode in a supernova after only a few million years of fusion.

Our Sun is an average sized star: there are smaller stars and larger stars, even up to 100 times larger. Many other solar systems have multiple suns, while ours just has one. The Sun is composed almost entirely of hydrogen and helium gas.

Thus, one comparison in the events in the life of the Sun with those of a star that starts with a mass 10 times greater than the Sun's is a star that has a greater mass will die out faster.
