CloudLabs Soil Pollution vs Earth Tide

In this laboratory, the contamination study is carried out in three soil samples from different sectors of the city. The student must measure the level of pH, conductivity, organic matter and the capacity to store nutrients and carbonates. For the development of the practice, there is a pH meter, a conductivity meter, and an Erlenmeyer flask, among other instruments.

Right now, the ground beneath your feet is rising and falling by tens of centimeters — and you can't feel a thing. Twice a day, gravity from the Moon and Sun stretches the entire solid Earth into a slow, planet-sized bulge. Earth Tide makes that invisible motion visible, in real time, anywhere on the planet. WHAT YOU CAN DO • Tide Chart — Watch vertical ground displacement in millimeters. Pan, zoom, and scrub through time to pinpoint exact peaks and troughs over hours, days, or weeks. • Tidal Compass — A live overlay shows where the Moon and Sun are pulling the ground right now. Switch to AR mode and point your camera at the sky to see the forces around you. • 3D Globe — Spin a rotatable, color-coded Earth and watch the tidal bulge sweep across continents and coastlines. • Anywhere on Earth — Use your current location or search any place in the world. SERIOUS SCIENCE, MADE SIMPLE Earth Tide is powered by the modern Yang et al. (2024) rotational-ellipsoid model, with published accuracy several times higher than the legacy method most tools rely on. The Moon does roughly 70% of the work; the Sun the other 30%. Whether you're a student, scientist, surveyor, or simply curious, you're seeing real geophysics.
