Answer: Without gravity there would be no atmosphere surrounding earth:
TRUE.
Explanation: With the removal of gravity from the earth, the atmosphere on the earth would be removed and everything even the atmosphere would be transported to space. Gravity is a respect of the mass which is what is holding the earth.

Answer:
Chondrichthyes characteristics include a cartilaginous skeleton, lack of a swim bladder, lipid storage restricted to the liver, unique hematopoietic organs, and bacteremia in clinically normal individuals. Variable reproductive strategies are employed throughout this vertebrate class
Explanation:
a) Warm air rises and cool air sinks : Convection
b) Sun rays warming a puddle : Radiation
c) An egg on a hot skillet : Conduction
d) Boiling water in a pan : Convection
e) Lava lamp : Conduction, Convection, Radiation
f) Feeling the suns heat on your neck : Radiation
g) Stepping on hot sand : Conduction
<h3>
Explanation:</h3>
Convection: The mode of heat transfer involving fluids: liquids and gases due to convection currents produced in the fluids are termed as heat transfer due to convection. The <u>dense cool air sinks,</u> air currents push the warm air upwards and thus rising warm air is an example of convection. Boiling water is similarly warm water rising and cool water sinking; the provided heat produces <u>convection currents</u>. Boiling water in a pan is an example of convection.
Conduction: Heat transfer by direct contact between substances is called conduction. An egg on a hot skillet is fried by conduction. The hot frying pan transfers the heat to the egg. The metal frying pan and egg are <u>in contact </u>with each other. Stepping on hot sand makes us feel warm since the hot sand and our feet are <u>in contact</u>. Heat gets transferred through conduction.
Radiation: A puddle getting warm due to sun rays and feeling the sun's heat on our neck is clearly heat transfer due to radiation. Sun rays are <u>electromagnetic waves</u> that are capable of transferring heat energy. The materials are in no direct contact with each other in case of radiation.
A <u>lava lamp</u> shows all three heat transfer modes in different ways. The incandescent light bulb emits light and warms the metal at the bottom of the glass tube through <u>radiation</u>. The heat transfer between the metal below the tube and the liquid inside is through <u>conduction</u>. The flow of liquids with different densities (upward and downward) inside the glass tube is due to <u>convection</u> currents generated in the liquid mixture.
Answer:
Pasture and cropland occupy around 50 percent of the Earth's habitable land and provide habitat and food for a multitude of species. When agricultural operations are sustainably managed, they can preserve and restore critical habitats, help protect watersheds, and improve soil health and water quality. in addition to preserving the earth's natural resources, sustainable agriculture benefits the environment through helping maintain soil quality, reducing erosion, and preserving water. Plants and trees in agricultural systems help to retain and add water to underground aquifers. ... Together, they act as an important buffer in the landscape, preventing flooding, reducing water pollution from agricultural runoff and preventing erosion, while providing us with nutritious food at the same time. Farming creates opportunities to lift people out of poverty in developing nations. Over 60 percent of the world's working poor works in agriculture. Farming creates more jobs, beginning with farmers, and continuing with farm equipment makers, food processing plants, transportation, infrastructure and manufacturing.
