Basalt, a dark volcanic rock, primarily makes up the ocean basins' foundation.
why there are five oceans?What five oceans are there? The Pacific Ocean, Atlantic, Indian Ocean, Arctic Ocean, and Southern Ocean are the five names of the oceans. Today, the earth's surface is covered by five bodies of water, including our one world ocean, five oceans (also known as Ocean 5), and two seas, which together account for more than 97 percent of the planet's water.
When did the ocean last experience freezing?According to geological evidence, the oceans may well have locked at least twice in the past. The previous occurrence was about 650 million years old. The fossil record is poor, yet enough single-celled animals did survive that cataclysm to repopulate the Earth.

landslides into bays and lakes can generate huge tsunami of local extent. what is it about bays and lakes that allows the tsunami to be so large? multiple choice question.
Large tsunamis with a local scope can be produced by landslides into bays and lakes. Due to their constrictive topography, bays and lakes frequently experience massive tsunamis.
A bay is a body of water that is partially enclosed by land; it is often smaller and less constrained than a gulf. The bay's mouth, however, is larger than the gulf. The underwater topography offshore mostly determines the wave height, which rises as it approaches the beach. Greater tsunami waves typically result from steeper shorelines. Lacustrine conditions are also susceptible to tsunamis. Vast-scale mass-movement mechanisms that displace large volumes of water and are sparked by seismic or aseismic phenomena are the principal causes of the enormous tsunamis in lakes.

the process in which sediments, soil and rocks are added to a land form or land mass.a. trueb. false
This statement is true. Deposition is a geological process that involves the addition of soil, rocks, and sediments to a landform or landmass.
Transported by wind, ice, water, and gravity, previously weathered surface material is deposited when enough kinetic energy in the fluid is lost, forming layers of sediment.
The null-point hypothesis states that deposition occurs when sediment transportation-related forces are no longer strong enough to overcome gravity and friction-related factors, which provide a resistance to motion. Deposition also refers to the buildup of sediment caused by organic or chemical processes. Chalk contains small calcium carbonate skeletons from marine plankton, which when deposited caused chemical reactions (diagenesis) to deposit more calcium carbonate.

what forecasting technique says that upstream weather will persist, and then move on to affect new areas in its path?
The forecasting technique that says that upstream weather will persist before then move on to affect new areas in its path is the trend technique or trend method.
Trend technique is a technique in forecasting that is used when the related phenomenon is in a steady state or is moving at a constant speed. It's more accurate on a shorter time scale (minutes to hours), so it's also known as the "nowcasting" technique. This method involves finding out the speed and direction of movement for things like fronts, pressure centers, and areas of precipitation and clouds.
Besides the trend technique, there are other techniques that can be used to produce a forecast. Some examples are the persistence method, climatology method, analog method, and numerical weather prediction.

A sand dune is a pile of loose sand grains of sand that have accumulated due to wind movement.
Only under certain conditions, such as the following, can sand dunes form:
The occurrence of a sizable sand supplyA steady wind source to transport and drop sandThe presence of a region with some vegetation, such as a dried-up riverbed, beach, waterfront, island, or desertThe existence of a protected area where a new sand dune can form, such as a rocks, tree, or another dune.Winds that are blowing at least 17 miles an hourLeeward and windward faces are the two sides or sides of sand dunes. The Leeward side refers to the area of the sand dune protected from the wind or facing away from it, whereas the windward side designates the area of the dune facing the wind.
Usually, the wind will blow sand over the dune's peak, creating a steep slope on the leeward side. The slip-face of the dune or the downwash side of the sand dune are terms used to describe this peak. The gently sloped part of the dune is represented by the windward side in contrast.

how do we use magnetic alignment of minerals in rocks to understand plate movements over time? (especially sea floor rocks and paleogeography of supercontinents)
Geologists can use the magnetic alignment of minerals in rocks to understand plate movements over time by studying the patterns of magnetic minerals in rocks. When rocks form, the minerals within them become aligned with the Earth's magnetic field. This alignment is preserved in the rock as it cools and solidifies. By studying the alignment of these magnetic minerals in rocks, geologists can determine the orientation of the Earth's magnetic field at the time the rock formed.
Over time, the Earth's magnetic field has reversed many times, with the north and south magnetic poles switching places. By studying the alignment of magnetic minerals in rocks of different ages, geologists can determine when these reversals occurred. This information can then be used to understand the movement of tectonic plates over time, as well as the formation and breakup of supercontinents.
For example, geologists can study the alignment of magnetic minerals in rocks on the sea floor to understand the movement of tectonic plates over time. By looking at the patterns of magnetic alignment in these rocks, geologists can determine the direction and rate of movement of the plates and how they have changed over time. This information can be used to understand the formation and breakup of supercontinents, as well as the history of plate tectonics on Earth.

Water is necessary for both plant and animal cells to carry out their fundamental tasks, such as moving materials, distributing waste, producing genetic material, and many other things. As a result, it is clear that if any of these cells were to get dehydrated, a severe issue would arise since the cytoplasm and plasma membrane would be unable to perform protein synthesis and other crucial tasks, causing them to partially shut down. A chemical compound is a substance that is made up of numerous similar molecules made up of atoms from different elements and kept together by chemical bonds. Chemical compounds cannot be created when atoms of the same element are bound together in a molecule because this would need the presence of two separate elements. The body depends on inorganic substances for a variety of basic processes. Water (H2O), bimolecular oxygen (O2), carbon dioxide (CO2), and a few acids, bases, and salts are the main inorganic substances. 60–75% of the body is made up of water. it aids in chemical processes, cellular structure and size, and temperature regulation in the cell.
