I would say winds drive surface currents
Answer: For flowering plants, fertilization occurs through a process known as double fertilization. Unlike most plants, double fertilization enables the new seed to grow into a new plant and have a food source to begin growing. Double fertilization occurs within the female part of a plant, the pistol.
explanation: When pollen is formed by the anther, or male part of a plant, it will blow in the wind or attach to an organism that carries it to the top of the pistol, known as the stigma. Once the pollen attaches to the stigma, the pollen germinates and forms a pollen tube that extends into the ovary. Once formed, two sperm cells will be released and fertilize both the egg and the two polar nuclei of the plant to form the zygote and endosperm, respectfully.
The geosphere and biosphere has co-evolved. It has been understood that life has evolved from organic matter over 4 billions year ago. The changes in the composition of water bodies influence the geophysical changes on the earth that in turn influences the evolution of new life on the earth.
Ocean and atmosphere are known to appear over 4.5 billions years ago. The earth was also newly born and eruption of volcanoes added gases to the atmosphere. Water also started flowing from the oceans into smaller water bodies to form seas, rivers, lakes and ponds. The earth was also in its beginning phase of the life where interaction between heat, gases, water, minerals were taking place. These interactions also led to the origin of life on the earth.
The Earth's atmosphere began to change with the course of time and 4 billions years ago, it had the atmosphere and climate to support the first life.
Answer:
Chemical rocks form when minerals dissolve in a solution and crystalize.
