where do new sections of crust come from during seafloor spreading?

Answers

Answer 1

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.

Answers

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.

what are sea breeze and land breeze *long answer though*​

Answers

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.
