Maria described two layers of earth's atmosphere. layer a: weather changes take place here layer b: location where weather balloons collect data which statement is most likely true? layer a is the thermosphere and layer b is the exosphere. layer a is the exosphere and layer b is the thermosphere. layer a is the stratosphere and layer b is the troposphere. layer a is the troposphere and layer b is the stratosphere.

Layer A is the troposphere and Layer B is the stratosphere.

Explanation:

The troposphere (layer A) is the closest atmosferic layer of the earth. This layer extends up to 20 km from the ground at the equator and approximately 10 km at the poles.

It is the air in which we live, breathe and where natural phenomena such as rain, snow, winds and lightning occur. It is also in the troposphere that air pollution occurs. Cargo and passenger aircraft fly in this layer.

Temperatures in this layer may range from 40 ° C to –60 ° C. The higher the altitude the lower the temperature.

The stratosphere(layer B) is the second largest layer of the earth's atmosphere, situated between the troposphere and the mesosphere.

It lies at 50 km altitude from the surface and houses the ozone layer. For this reason the stratosphere is rich in ozone gas and poor in oxygen gas, and weather balloons and supersonic airplanes travel in this layer.

the number of protons in the nucleus of a given element. has slight luster and conducts electricity at high temperatures like metal.but like a nonmetal,boron is brittle and does not conduct electricity well at low temperatures. in graphite, carbon is a soft,brittle solid.it is reflective,ductile,or malleable.
