Answer:
The uppermost portion of the mantle makes up the bottom portion of the lithosphere. On average, it is 30 kilometers thick, but its thickness depends on the age of that portion of the lithosphere and temperature and pressure conditions. The mantle consists largely of heavy ultramafic rock like olivine.
Explanation:
The mantle is made up of molten rock called magma. This magma circulates in currents determined by the cooling and sinking of heavier minerals and the heating and rising of lighter minerals. All but the very uppermost portion of the mantle is part of the asthenosphere, which refers to the liquid zone of the inner Earth.
Answer: Option A) receiving; sending
Explanation:
The neuron is made up of many parts, they include:
- dendrites, which are branched and helps in receiving impulses from the adjacent neuron
- axon, a long and extended portion of the neuron that the transmission of impulses along its length away from the cell body.
- synapse etc
Thus, dendrites of neurons is involved in receiving impulses into the neuron, while axons is involved in sending impulses away from the neurons
Ability to absorb infrared light: Every molecule absorbs energy. ... Only gases that are able to absorb what infrared light is left over will contribute significantly to climate change. Methane can absorb the infrared light that water vapor leaves behind, which contributes to its higher climate change potential.
The greenhouse effect causes some of this energy to be waylaid in the atmosphere, absorbed and released by greenhouse gases. Without the greenhouse effect, Earth's temperature would be below freezing. It is, in part, a natural process.
