Global winds and ocean currents are responsible for distributing global heat, which directly affects continental climates. To understand how these currents form, a knowledge of the impacts of Earth’s motion is necessary. Was this helpful?
The Earth’s rotation on its axis causes ocean currents and winds to curve to the right (clockwise direction) in the Northern Hemisphere and to the left (counter clockwise direction) in the Southern Hemisphere. As the winds and currents move, the Earth rotates underneath them. The currents appear to curve in relation to the Earth’s surface.
Surface currents, which make up only 8% of all water in the ocean, are generally restricted to the upper 400 m (1,300 ft) of ocean water, and are separated from lower regions by varying temperatures and salinity which affect the density of the water, which in turn, defines each oceanic region.
Flower diagram below shows typical parts of a flower in nature. A great diagram to help kids learn about biology and flowers in particular.
Here we will discuss the structure of human skin, … and keeps water in. It is composed of layers of flat cells called “squamous” cells.
The Individual Layers of Skin and Their Functions. 1 The Epidermis. The epidermis is the outermost layer of the three layers of skin. Its thickness depends on where it is located on the body. For … 2 The Dermis. 3 The Subcutaneous Tissue.
The skin and its accessory structures make up the integumentary system, which provides the body with overall protection. The skin is made of multiple layers of cells and tissues, which are held to underlying structures by connective tissue (Figure 1). The deeper layer of skin is well vascularized (has numerous blood vessels).
The Structure And Function Of The Human Brain. The brain structure is composed of three main parts: the forebrain, midbrain and hindbrain, each with multiple parts. The Cerebrum: Also known as the cerebral cortex, the cerebrum is the largest part of the human brain, and it is associated with higher brain function such as thought and action.
The human brain controls nearly every aspect of the human body ranging from physiological functions to cognitive abilities. It functions by receiving and sending signals via neurons to different parts of the body.T he human brain, just like most other mammals, has the same basic structure, but it is better developed than any other mammalian brain.
Brain Structure & Function offers free color in print and online for all its papers! Brain Structure & Function publishes research that provides insight into brain structure−function relationships.
The rock cycle is a concept of geology that describes the transition of rocks between the three rock types: igneous, sedimentary, and metamorphic. The cycle outlines how each rock type can be converted to another rock type through geologic processes.
Steps of the Rock Cycle: How does it Work 1) Formation of Igneous Rock – Melting, Cooling, and Crystallization Magma, the molten rock present deep inside the earth, solidifies due to cooling and crystallizes to form a type of rock called igneous rocks.
The rock cycle is a series of processes that create and transform the types of rocks in … Active volcanoes like this one on Reunion Island—east of Madagascar, in the Indian Ocean—forms a type of igneous rock. Extrusive, or volcanic, igneous rocks are formed when molten hot material cools and solidifies. Photograph by Steve …
The cerebrum, originally functioning as part of the olfactory lobes, is involved with the more complex functions of the human brain. In…. The cerebral hemispheres consist of an inner core of myelinated nerve fibres, the white matter, and an outer cortex of gray matter.
The cerebrum is made up of the two cerebral hemispheres and their cortices, (the outer layers of grey matter), and the underlying regions of white matter. Its subcortical structures include the hippocampus, basal ganglia and olfactory bulb.
Hindbrain functions: The three regions of the hindbrain coordinates all processes necessary for survival. These induce breathing, heartbeat, sleep, wakefulness and motor learning. The cerebrum is the largest part of the brain. It consists of the cerebral cortex and other subcortical structures.
Carbon cycle diagram shows how carbon cycles through nature from one form to another. The below carbon diagram explains the natural cycle.
To better understand the structure and function of a microscope, we need to take a look at the labeled microscope diagrams of the compound and electron microscope. These diagrams clearly explain the functioning of the microscopes along with their respective parts. Man’s curiosity has led to great inventions. The microscope is one of them.
Here, unlabeled microscope diagrams have been provided for your perusal, which will help you practice and test your understanding of the instrument. Depending on the source of illumination, microscopes can be divided into two categories. They are:
A simple microscope’s parts have two classifications: the mechanical part and the optical parts. What are the mechanical parts? Mechanical parts pertain to the parts of the microscope that support the optional parts. They help in the adjustment so as to accurately magnify the object. Mechanical parts include the following:
Animal Cell Definition: Animal cells, which are the fundamental units of life in the Animal Kingdom, are eukaryotic cells. This means that they contain a true (membrane-bound nucleus) along with other membrane-bound organelles.
An animal cell is a type of cell that differs from plant or fungi cells. Like plant and fungi cells, an animal cell is eukaryotic, but animal cells lack the cell wall structure found in plant and fungi cell types. Animal cells also do not contain chloroplasts as plant cells do, as animal cells are heterotrophic and do not perform photosynthesis.
