What do you call a molten hot liquid rock once it erupts to the Earth’s surface?

What do you call a molten hot liquid rock beneath Earth’s surface?

Which of the following is the direct transfer of heat from one molecule to an adjacent one?

Which of the following is the process by which material circulates through a region that is unevenly heated?

Pyrite exhibits gold color. When scratched in a white tile, it leaves black or dark gray streak. Pyrite’s true color is gold. If the first two statements are true, then the third statement is?

Biosphere is the set of all life forms on Earth. This includes life on land, in the oceans and rivers, and even life that we cannot see with the naked eye. Viruses are part of the biosphere. If the first two statements are true, then the third statement is?

Since life exists on the ground, in the air, and in the water, the biosphere overlaps all these spheres. Humans play an important part in maintaining the flow of energy in the biosphere. Decrease in oxygen level, and increase in carbon dioxide levels, oil spills, industrial wastes and other human activities disrupt this flow. If the first two statements are true, then the third statement is?

Gravity on earth is 9.8m/s².Gravity on mars is 3.7m/s².  Under Mars’ gravity, you would weigh less than your weight under Earth’s gravity. If the first two statements are true, then the third statement is?

Atmospheric pressure is the force exerted on a surface by the air above it as gravity pulls it to Earth. It drops as altitude increases. So, when you go deep into the world’s deepest ocean, you would eventually experience pressure dropping. If the first two statements are true, then the third statement is?

The processes that move matter and energy from one sphere to another are called sphere interactions. El Niño Southern Oscillation (ENSO) is an example of hydrosphere-atmosphere interaction. This means, a change in one sphere, will not affect the other sphere. If the first two statements are true, then the third statement is?

Talc has a hardness of 1. Gypsum has a hardness of 2. Fingernail, with a hardness of≈2.5, can leave a scratch on these two. If the first two statements are true, then the third statement is?

Color and streak are two of the most important physical properties of mineral. Individual mineral can display a variety of colors depending on the substance it comes in contact with, while streak is the same in almost every mineral. This makes the color a more diagnostic property compared to streak. If the first two statements are true, then the third statement is?

Fluorite has a hardness of 4. Quartz has a hardness of 7. If quartz and fluorite will be scratched against each other, fluorite will scratch quartz. If the first two statements are true, then the third statement is?

Topaz has a hardness of 8. Diamond has a hardness of 10. If topaz and diamond will be scratched against each other, diamond will scratch topaz. If the first two statements are true, then the third statement is?

Identification: It is a circular depression which form through dissolution of underlying soluble rocks or the collapse of a cave’s roof.

Identification: It refers to the mineral’s ability to transmit light.

Identification: It refers to the tendency of minerals to break other than along planes of weakness.

Identification: Based on the Mohs scale of hardness, what mineral is softer than gypsum?

Identification: What do you call an exogenic process that causes rocks and minerals to break down?
