Which of the following are evidence of past liquid water on the Martian surface sort as true or false?

Which of the following are evidence of past liquid water on the Martian surface sort as true or false?

Notice that there is no evidence of any Martian civilization past or present, but there is evidence that Mars once had surface liquid water, which raises the possibility that it might still have underground pockets of liquid water and, perhaps, microscopic life. You just studied 53 terms!

Which two represent the two facts that lead us to expect Earth to be warming up as a result of human activity?

Human activity is increasing the concentration of carbon dioxide and other greenhouse gases in the atmosphere. Greenhouse gases make Earth warmer than it would be otherwise.

Why does Mars’s axis swing much more wildly over time than Earth’s?

Why does Mars’s axis swing much more wildly over time than Earth’s? Mars lacks a large moon. All of Mars has summer at the same time, and half an orbit later all of Mars has winter.

What is the main reason that Mars compared to Earth has become so geologically inactive?

Ch7 concept quiz

Question Answer
What’s the fundamental reason that Mars, unlike the Earth, has become virtually geologically dead? its small size compared to Earth

Why does Mars have no tectonic plates?

Like Earth, Venus and Mars are believed to have hot interiors. This means that they are continuing to lose heat. While their surfaces show evidence of recent deformation — tectonism — neither planet has plate tectonic activity because neither planet has a surface divided into plates.

Which two factors are critical to the existence of carbon dioxide cycle on earth?

astronomy final shelley

Question Answer
Which characteristic of Earth explains why we have an ultraviolet-absorbing stratosphere? the existence of photosynthetic life
Which two factors are critical to the existence of the carbon dioxide (CO2) cycle on Earth? plate tectonics and liquid water oceans

What is the largest pool of carbon on the planet?


What is the relationship of carbon and greenhouse gas effect?

Burning fossil fuels like coal and oil puts more carbon dioxide into our atmosphere. NASA has observed increases in the amount of carbon dioxide and some other greenhouse gases in our atmosphere. Too much of these greenhouse gases can cause Earth’s atmosphere to trap more and more heat. This causes Earth to warm up.

What would happen if carbon dioxide is removed from the air?

Answer. All plants would die because they do not have the CO2 to make food with. So if there was no carbon dioxide, we couldn’t get sufficient air, we can’t breathe it out, and plants start to die.

How do you remove CO2 from the air in your home?

Here are six options for removing carbon from the atmosphere:

  1. 1) Forests.
  2. 2) Farms.
  3. 3) Bio-energy with Carbon Capture and Storage (BECCS)
  4. 4) Direct Air Capture.
  5. 5) Carbon Mineralization.
  6. 6) Ocean-based Concepts.
  7. The Future of Carbon Removal.

Which does not produce carbon dioxide?

Photosynthesis. Cellular Respiration. Burning fossil fuels.

What will happen to our world in the absence of carbon dioxide?

Carbon dioxide is an important greenhouse gas that helps to trap heat in our atmosphere. Without it, our planet would be inhospitably cold.

Can we live without CO2?

Carbon dioxide—CO2—is an essential part of the cycle of life. Without a source of CO2, plants will die off, and without plant life the earth’s biological food chain would be terminally broken. The carbon found in biomass is taken out of the atmosphere through the process of photosynthesis which causes the plant grow.

Can we remove CO2 from the atmosphere?

Another way of extracting CO2 from the air is via biomass. Plants grow and are burned in a power plant to produce electricity. CO2 is then extracted from the exhaust gas of the power plant and stored deep in the Earth.

Is carbon bad to your health?

Chronic inhalation exposure to carbon black may result in temporary or permanent damage to lungs and heart. Pneumoconiosis has been found in workers engaged in the production of carbon black. Skin conditions such as inflammation of the hair follicles, and oral mucosal lesions have also been reported from skin exposure.

What does Black carbon do to the human body?

), including black carbon, can cause premature death and harmful effects on the cardiovascular system (the heart, blood, and blood vessels). health problems, including respiratory diseases. (including asthma), older adults, children, and people of lower socio- economic status.

Is it OK to drink the carbon from water filters?

Consuming activated carbon dust or particles from Brita filters is not harmful. However, there are no studies that support this and it is unlikely that ingesting carbon at such low quantities from filtered water would be of any real concern. So, it’s perfectly ok to drink the carbon from water filters!

What percentage of CO2 is dangerous?

Exposure Effects

Exposure limits (% in air) Health Effects
15 Lethal concentration, exposure to levels above this are intolerable
25+ Convulsions occur and rapid loss of consciousness ensues after a few breaths. Death will occur if level is maintained.

What level of CO2 is fatal?

The Center for Disease Control has designated 100,000 ppm of carbon dioxide as life-threatening, or “immediately dangerous to life.” More recently, Dr. Peter Harper of Health and Safety Executive has determined that exposure to lower levels, starting at 84,000 ppm for 60 minutes or more, will also result in fatality.

How many ppm CO2 is dangerous?

40,000 ppm

What are safe levels of CO2 in rooms?

Normal CO2 Levels acceptable levels: < 600 ppm. complaints of stuffiness and odors: 600 – 1000 ppm. ASHRAE and OSHA standards: 1000 ppm. general drowsiness: 1000 – 2500 ppm.

How can CO2 levels be reduced?

Replace your air filters and any other parts as needed to improve ventilation and lower CO2 levels in your home.

  1. Design your home to support airflow.
  2. Limit open flames.
  3. Incorporate plants in your home.
  4. Increase airflow while cooking.
  5. Limit your exposure to VOCs.

Is a CO2 level of 30 high?

Normal values in adults are 22 to 29 mmol/L or 22 to 29 mEq/L. Higher levels of carbon dioxide may mean you have: Metabolic alkalosis, or too much bicarbonate in your blood. Cushing disease.

What are signs of acidosis or alkalosis?

Some of the common symptoms of metabolic acidosis include the following:

  • rapid and shallow breathing.
  • confusion.
  • fatigue.
  • headache.
  • sleepiness.
  • lack of appetite.
  • jaundice.
  • increased heart rate.

Can anxiety cause low CO2 levels in blood?

Respiratory alkalosis occurs when a person breathes too rapidly (hyperventilation), causing more CO2 to be expelled out of the body. This lowers CO2 levels and increases blood pH. Hyperventilation may be caused by many different factors, such as stress, anxiety, fever, and lung disorders [6].

What if my CO2 is high?

Abnormal results may indicate that your body has an electrolyte imbalance, or that there is a problem removing carbon dioxide through your lungs. Too much CO2 in the blood can indicate a variety of conditions including: Lung diseases. Cushing’s syndrome, a disorder of the adrenal glands.

How do you get rid of carbon dioxide in your body naturally?

Exercise forces the muscles to work harder, which increases the body’s breathing rate, resulting in a greater supply of oxygen to the muscles. It also improves circulation, making the body more efficient in removing the excess carbon dioxide that the body produces when exercising.

How do you remove carbon dioxide from your body?

CO2 is transported in the bloodstream to the lungs where it is ultimately removed from the body through exhalation.

Can dehydration cause high CO2 levels?

High CO2 in blood may point to: Lung diseases like COPD, or chronic obstructive pulmonary disease. Dehydration. Anorexia.
