The weaker, denser layer below the lithospheric mantle is known as the asthenosphere. It is between 62 miles and 410 kilometers (100 miles) below the surface of the Earth!
What is the earth?Only one astronomical object—Earth, which is third from the Sun—is known to support life. Although the Solar System contains enormous amounts of water, only Earth is home to liquid surface water. The oceans cover around 71% of Earth's surface, dwarfing its lakes, rivers, and polar ice.
The Earth's upper mantle contains the ductile and mechanically feeble asthenosphere. It stretches as far as 700 km beneath the lithosphere, between 80 and 200 km below the surface. However, the asthenosphere's lower border is not clearly defined.

What effect did tectonic plates have on the Saraswati river and what happened as a result?
The Saraswati River dried up due to tectonic activity.
What and where is the Saraswati River?
A deified river initially referenced in the Rig Veda and later in Vedic and post-Vedic texts is the Saraswati River. Despite only appearing in the fourth book of the Rigveda, it was a significant part of the Vedic religion. As a physical river, the Rig Veda's earliest writings refer to it as a "large and holy river in north-western India," but its later writings refer to it as a "little river ending in a terminal lake (samudra)." The river is also referred to as a forceful river and a mighty flood, just like the goddess Sarasvati, the second referent for the term "Saraswati," which evolved into an autonomous identity in post-Vedic times.
Hence, it is believed that the Saraswati River dried up due to tectonic shifts of the Earth.

What is the likeliest limiting factor restricting phytoplankton to approximately the top ten feet of the ocean, rather than deeper?.
The likeliest factor why phytoplanktons are limited to the top ten feet in the seas and oceans is due to the dependence of such organisms on sunlight for their living and also manufacturing of food on their own.
Phytoplanktons are the microscopic, marine algae which are autotrophs in nature and are found under water. They are important sources of marine food and also serve as nutrient sources for the marine ecosystem. Phytoplankton are dependent on sunlight and their CO2-fixation activity, which makes it important for them to remain in the top layer of water streams where sunlight can penetrate, and exchange of oxygen and carbon dioxide can take place.

Why does sediment get deposited where a stream meets the ocean, forming a delta?.
The silt carried by a river is dumped in a fan-shaped structure known as a delta where it meets the sea. Sand bars, spits, and barrier islands are examples of shoreline sediment structures that are formed as a result of the silt being picked up and transported by longshore drift.
When rivers discharge their water and sediment into another body of water, such as the ocean, a lake, or another river, wetlands known as deltas occur. Deltas can also drain into land, though this is extremely unusual. The closer a river gets to its mouth or finish, the slower it flows. Sediment, or solid material transported downstream by currents, is subsequently deposited at the river's bottom as a result.
Subaerial and subaqueous regions can be separated into separate portions of a delta. A delta's subaqueous region is submerged. This area of the delta slopes the steepest and has the purest silt. The pro delta is the newest region of the subaqueous delta and is located farthest from the river's mouth.

if earth had no oceans, would the tropics (near the equator) be warmer or colder? explain your answer.
If the earth had no oceans, then the tropical regions would be comparatively warmer.
The earth without the ocean would be super-hot at the equator and really cold at the poles. The warming at the equator increases the temperature and the warm air rises. Without oceans, there will not be any winds flowing which will cause moderation of temperature, due to which extreme temperatures will be experienced in places such as extreme cold in the frigid zone and extreme heat in the equatorial region. Though temperature at tropics would be comparatively lower than equatorial region, still it would be high for the person to live in such areas hospitably.

The rate of sea floor spreading of Mid Oceanic Ridge is 1 cm per year.
Spreading rates determine if the ridge is fast, intermediate, or slow. 1Ma is the acronym for Million annum, which represents the time period of a million years. A mid-ocean ridge (MOR) is a seafloor mountain system formed by plate tectonics. It occurs along the divergent plate boundaries, where new floor formation takes place due to the movement of tectonic plates away from each other. The rate of spreading can be equated from the equation given below:
Rate of Spreading of seafloor = [distance the sea floor moved] / [duration of time taken]
R = D/T ...(1)
Distance seafloor moved = D = 45km = 4,500,000 cm
Time taken for spreading = T = 4.5Ma = 4.5 * 1,000,000 years
