Tsunamis and earthquakes
Answer:
D. Reversal of Earth's magnetic field
Explanation:
The earth's magnetic field changes over time and this causes changes in the direction of magnetization of magnetic elements or minerals in rocks.
Our magnetic field is widely believed to originate from activities within the outer core where molten iron and nickel moves. The flow of these molten elements results in the production of the magnetic signatures on earth surface.
Some elements and minerals within rocks are capable of recording the direction of magnetic fields at a period in time. Before magma cools, such minerals in these rocks aligns their poles to that of the prevailing direction of the earths magnetic field. This is how the magnetic changes at the mid-oceanic ridges are recorded.
Answer:
The process of seafloor spreading is responsible for "creating magnetic changes" along mid-ocean ridges.
Explanation:
The answer is to help produce food. Agriculture means stuff like food, therefor it's to help grow food. Also, I took the test on E2020 and got it right.
Answer:
C. helping to produce food
Explanation:.
Sediment enriches the soil with nutrients and rich in biodiversity. This soil works great for farming. The deposition of sediments makes the agricultural areas like deltas and river banks more fertile.
Glaciers carry a huge range of sediment with several sizes. With continues deposition, space for the animal and plant life gets reduced.
The most dangerous part is that the animal’s may suffocate and intervention may occur with their food intake.
Geospatial and geographic data are used widely from individuals to governments. They help to understand spatial relationships and patterns which can be applied for various purposes such as route planning, site selection, market analysis, research, urban planning, and disaster management.
Geospatial and geographic data are used at all scales for various decision-making purposes. These types of data provide essential information about the physical location and layout of the earth's features, human-made systems, and phenomena that occur on our planet. They are visual representations that help individuals, businesses, organizations, and governments to understand spatial relationships and patterns.
For individuals, geospatial data can be used to analyze commuting patterns, define routes and access local services. Businesses use geospatial data for site selection, supply chain management, and market analysis. On an organizational level, bodies like non-profits or research institutions use these data to assess environmental impacts, conduct research, or plan development projects. Government entities use geographic data for everything from traffic management to urban planning and disaster management.
For instance, a municipality might use geospatial data to identify areas prone to flooding and then make decisions about infrastructure development.

Geospatial and geographic data are essential for a wide variety of decision-making processes, spanning personal use to governmental planning. They help in visualizing spatial relationships and are used in navigation, business planning, and governmental decision making. These data can be collected through numerous methods and can be visually displayed for easier analysis.
Geospatial and geographic data are vital elements used across a variety of sectors and scales. They are used to understand and visualize spatial relationships, making them important in personal, business, organizational, and governmental decision-making processes.
In personal contexts, they can be used for navigation and exploration through applications like Go-ogle Maps. In business and organizations, these data are used for logistics, planning, and risk management. For example, a company might use geographic data to choose a location for a new branch or to ensure a delivery route is efficient. Governments use such data for land management, urban planning, environmental protection, and emergency response among many others.
Geospatial data can be collected through various methods like surveys, remote sensing technologies (like satellite imagery), and can be displayed through maps, charts, or software applications, enabling users to analyze visually and make data-driven decisions.
