Environmental Science (reviewer)

The interdisciplinary field and requires the study of theinteractions among the physical, chemical and biological comp..

Inner core is the liquid layer made up of iron and nickel

who first studied the motion of lithosphere over a molten layer like asthenosphere.

Mantle and core boundary is called as WEICHART GUTENBERG Discontinuity.

The non living factors or the physical environment prevailing in an ecosystem form theabiotic components

Flooding, Volcanic eruptions and Forest Fires is example of threats to climax communities

the process by which water on the surface changes from a liquid to a gas state, water vapor.

happens when water vapor returns to the air from the leaves of plants.

the deepest layer of the earth

consisting of populations of different species that live together and interact with one another

The animals which feed on the herbivores

Elements are space, landforms, water bodies, climate, soils, rocks and minerals.

The air surrounding the earth?

refers to a close relationship in which one or both organism obtain a benefit

Elements such as economical, social and political elements are essentially manmade features

This is the most important layer of the atmosphere because all kinds of weather changes take place only in this layer

outermost layer of the earth with average density of 2.8 – 3.0 g/cm3 and average thickness of 30km.

Weather related incidents do not take place in this layer.

a symbiotic relationship where both organisms benefit

Include rain, temperature, light, wind, humidity etc.

The word ‘Environment’ is derived from the French word ‘________’ which means toencircle, around or surround.

An interaction in which one animal typically kills and consumes another animal

Wheat is example of decomposer

The biologist Jacob Van Uerkal introduced the term ‘environment’ in Ecology

They contain a mixture of weathered rock fragments, highly altered soil mineral particles and organic matter

derived from Greek word lithos meaning rocky or stone.

Theory of continental drift is the idea that the continents have moved horizontally to their current locations.

A natural functional ecological unit comprising of living organisms and their non-living environment

The two main gases in the atmosphere and 99 percentage of the atmosphere is made up of these two gases.

What type of plate boundaries

Bios (water) sphere

area that was previously occupied by living things is disturbed, then re-colonized following the disturbance

describe the interactions between and among organisms within their environment.

the driving force of plate tectonics in which hot, plastic like material from the mantle rises to the lithosphere

Used in ecosystems to heat the atmosphere and to evaporate andtranspire water into the atmosphere

is a series of progressive changes in the species that make up a community over time.

What type of plate boundaries

Fossils of Mesosaurs have been found in Asia and Antartica.

The medium by which mineral nutrients enter and are trans-located in plants

It contains electrically charged particles known as ions, and hence, it is known as the ionosphere.

consists of rain, hail, sleet or snow falling from clouds back to Earth’s surface.

These are the largest carnivores which feed on the tertiary consumers and are not eaten up by any other animal

the second layer of the earth and extends from 30 km- 2900km with an average density of 2.7 g/cm3

These are the large carnivores which feed on the secondary consumers.

a symbiotic relationship where one organism benefits and one does not benefit but is unharmed

Acts as a filter and absorbs the ultra-violet rays radiating from the sun and prevents them from reaching the surface

What type of plate boundaries

Gases form of water present in the atmosphere

There are 8 continents at the Earth

—when two or more organisms rely on the same environmental resource.

Found in the form of sand, smoke-soot, oceanic salt, ash, pollen, etc.

Environment is constituted by the interacting systems of _____, _____ and _____ elements inter-related in various way.

The Earth is divided into four sub-systems or sphere namely?

water from precipitation that flows over the surface into rivers or streams, eventually returning to the ocean.

The study of the interactions between an organism of some kind and its?

The sum total of land, water, air, interrelationships among themselves andalso with the human beings and other organism

Tiger is an example of consumer.

The living organisms including plants, animals and micro-organisms (Bacteria and Fungi) that are present in an ecosystem

Meteors or falling stars occur in this layer.

a stable group of plants and animals that is the end result of the succession process.

have a strong interest in understanding how communities form and change over time.

an interaction in which an animal consumes a producer, or plant. Usually, animals only eat a portion of a plant

Outer core the solid layer made up of iron and nickel

Chemistry, physics, life science, medical science, agriculture are some of branches of studies of environmental studies

Elements such as plants, animals, microorganisms and men constitute the biosphere.

These are the animals which feed on plants or the producers

—a symbiotic relationship where one organism benefits and one is harmed

newly exposed or newly formed rock is colonized by living things for the first time

A multidisciplinary subject where different aspects are dealt within a holistic approach.

Radio waves transmitted from the earth are reflected back to the earth by this layer

occurs when water vapor in the atmosphere cools and collects into water droplets, forming clouds.

It absorbs a part of terrestrial radiation and reflects back some part of it towards the earth’s surface.

Lithos (rocky or stone) sphere
