Seafloor spreading occurs at divergent plate boundaries. As tectonic plates slowly move away from each other, heat from the mantle's convection currents makes the crust more plastic and less dense. The less-dense material rises, often forming a mountain or elevated area of the seafloor. Eventually, the crust cracks.

What can you find in the top layer of dense canopies in rainforests? The top layer has that grow to heights of meter(s) or more, which does not allow much sunlight to enter the canopy.
The canopy of a rainforest is defined as the top layer present 30 meters above the ground, which is made up of the overlapping leaves and branches of the trees.
The top layer of the canopies is known as the emergent layer that consists of a large number of trees and extends in height to all the plants.
What is the canopy of the rainforest?The long and enormous trees of the rainforest are extended to reach the direct sunlight. The canopy formed due to the overlapping of trees blocks out the sunlight available to the plants present beneath the canopy. 60-90% of the life forms are found in the canopy of the rainforests. It is one of the richest habitats and has biodiversity.The root system of the rainforests is shallow, and the bark is thin and smooth as the rainforests do not deal with cold weather.
Thus, the canopy reaches a height of more than 30 meters to achieve direct sunlight.

why is the domestication of plants and animals seen as a form of artificial selection as opposed to natural selection?
There are different ways means of selection. Domestication of plants and animals is seen as a form of artificial selection because the process of domestication itself is known to be an artificial form of selection.
This is because one can easily makes selection of traits based on personal characteristics needed.It is said to lack the control of fitness needing to increase fitness and as such artificial selection can cause problem traits to be popular among species.
Controlled breeding leads to prezygotic selection which is a key element to domestication. This is due to the fact that captive breeding allows for the strongest, most straightforward artificial selection.

Is the density of an object and the hardness of an object related? Why or why not? PLZZZ
Yes, Density is directly related to the mass and the volume. In fact, it tells us of the exact relationship between the two. To find an object's density, we take its mass and divide it by its volume
Answer:
Answer Wiki. Since hardness measurement involves only surface of the material, bulk density of the material does not have any explicit relation with the hardness. Materials are usually subjected to microstructural and/or chemical changes in the surface by carbiding, nitriding and other processes, many times by cold working.

South America can be divided into three physical regions: mountains and highlands, river basins, and coastal plains. Mountains and coastal plains generally run in a north-south direction, while highlands and river basins generally run in an east-west direction.
Latin America is a heavily forested region, especially in the rainforests of Central America and South America. The Amazon Rainforest is the largest rainforest in the world, and the Amazon River runs through it to create a range of physical diversity.

what are sea breeze and land breeze *long answer though*
Answer:
sea breeze is a breeze that comes from sea and goes to land land breeze is the opposite so it would be land breeze is breeze coming from the land going to the sea pretty easy if you ask me
Explanation:
Answer:
Sea and land breezes occur due to the difference in the cooling rates of land and sea.
Sea breeze (occurs during the day):
During the day, land gains heat quicker than the sea. Air directly above land is thus heated up and rises due to expansion (larger volume, lowered density). Air from above the sea thus moves towards the land to occupy the space previously occupied by the air above land, from an area of high pressure to an area of lower pressure, forming wind.
Land breeze (occurs at nighttime):
At night/evening, land loses heat quicker than the sea. Air directly above the sea is thus warmer. It rises due to lower density. Air from above land thus moves towards the sea to occupy the space previously occupied by the air above the sea, from an area of high pressure to an area of lower pressure, forming wind.
The greater the temperature difference between the land and the sea, the stronger the wind.

Answer:
5 factors that affect the climate of India are:
1. Latitude: It is the value of latitude which determines tin which region of the earth India is located and based upon it the climate gets affected.
2. Altitude: It is a type of elevation in which the air pressure is very low and thus the temperature decreases which causes a cool climate.
3. Vegetation: High amount trees causes increase amount of rainfall, whereas less cover of forest leads to low amount of rainfall which in turn affects the climatic condition.
4. Wind: It is the nature of the wind which affects the climate. Warmer wind paves wave for colder climate and vice versa.
